Did you find some black, seed-like bugs crawling all over your bed? These are likely to be weevils, especially if you have regularly been eating in bed. In this article, we will talk about how to get rid of them.
Having any pest in your bedroom can be unsettling, and it’s especially true when we’re talking about small, black insects that infest in large numbers.
Yes, we are talking about weevils – the pest well-known for destroying large volumes of stored food. There are more than 60,000 types of weevils worldwide, and most of them are notorious for invading homes.
If these pests have somehow made their way to your bedroom, we’ll help you figure out how to get rid of them.
What Are Weevils?
Commonly known as flour bugs, weevils belong to the Curculionidae family of insects. The elongated snout of a weevil is its most prominent identifying feature.
They use these elongated snouts, or rostrums, to feed on plant matter by boring through their tough protective coverings.
The most common types of weevils are the ones that infest pantries to feed on stored grains. They’re named after their preferred food grains, such as rice weevils, maize weevils, and so on.
Collectively, these weevils are all categorized as grain weevils.
There are other types, such as fruit weevils or vine weevils, but those are unlikely to come into your bedroom, so we will not consider them in this article.
A female weevil lays its eggs inside foodgrains and covers them up with a sticky substance, making it hard to find where she injected the eggs.
This explains why you can sometimes find these pests, even in packaged food. The eggs may hatch after a few days, and you will suddenly find weevils running around in your food.
How Do Weevils Come In The Bedroom?
Considering weevils are primarily drawn to stored food and grains, finding them in the bedroom might seem a bit unusual.
It’s normal for weevils to invade kitchens, but why would they want to stay in your bedroom? Well, there are several ways how they might have ended up there:
Eating in the Bedroom
While enjoying snacks in bed can be fun, it has a serious downside to it. Food particles falling on the bed can attract pests, especially weevils and ants.
Only a few weevils need to follow the smell of food to your bed for the others to follow. This is possibly the most common reason behind weevil infestations in bedrooms.
Open ingredients in the Kitchen
Another bad habit that can easily result in a weevil infestation is leaving food ingredients open in the kitchen.
Open ingredients, especially food grains, are a clear invitation to weevils. It won’t take long for the infestation to spread to your bedroom, especially if the previous reason is applicable too.
Weevils came in from an infested garden.
Maybe there’s a garden right next to your bedroom? Apart from food grains, weevils also feed on plants by infesting gardens.
As winter begins to set in, they start seeking sanctuary in warm indoor spaces. You may also get weevils in your bedroom from houseplants kept on an adjoining balcony.
Weevils came in with beddings aired in the garden
Airing your beddings out under the sunshine is a great idea unless there are weevils around.
Especially if your beddings have small bits of food on them, they can quickly attract weevils lurking around in your garden. Once you take them back indoors, you carry the pests along with them.
How To Prevent Weevils In The Bedroom
So now that you know why and how weevils can end up in your bedroom, let’s find out how you can prevent them from doing so.
It doesn’t take a lot of effort to keep your bedroom weevil-free; just a bit of precaution should be enough to keep these pests out.
Don’t Eat In Your Bed
Given that eating in bed is the biggest reason behind most weevil infestations in the bedroom, the most obvious solution is to get rid of this habit.
As long as you don’t eat in bed, you don’t have to worry much about dropping food debris that might attract those pests.
Note that weevils are attracted to pet food as well, so no feeding your dog near the bed.
Clean Your Bed Daily
You should clean your bed every day regardless of whether there are any weevils or not.
However, the risk of a weevil infestation makes it even more important. Even if you don’t eat in bed, food particles may sometimes end up there.
Simply taking a few minutes every day to clean your bed will help keep it free of any food debris that weevils would find attractive.
Deep Clean Your Room and Bedding Once a Week
Just like cleaning your bed daily, you should deep clean your room and bedding every week just for the sake of cleanliness alone.
However, if you don’t find this reason important enough, you should remember that a weekly deep cleaning will help you prevent weevil infestations.
Besides removing food particles from the corners of your room, you can also get rid of the few weevils that might be present already.
Check Your Kitchen For Weevils And Keep It Weevil Free
You may have come to this page only to find out how to get rid of weevils in the bedroom, but it’s important first to rid your kitchen of these weevils.
Remember, your kitchen is likely at the heart of the infestation. That is where most of them are holed up, destroying your food and multiplying in numbers.
Here are some tips on keeping these pests out of your pantry:
Inspect all packed food grains
If you find any weevils at home, go and check your kitchen thoroughly. Inspect all your bags of stored grains and other foods that they might infest. Finding the source will help you end the infestation at a budding stage.
Salvage whatever you can, and throw away the rest
The best way to deal with weevil-infested rice is to throw it away. However, if the infestation isn’t too bad and you don’t want all the rice to go to waste, you can salvage it.
Keep the rice in the sunlight for a couple of days – the heat will drive out the weevils. Washing the rice in water will cause the weevils to float up, too, making them easy to remove.
Don’t hoard grains
Don’t hoard large volumes of foodgrains in your kitchen – it will only increase the likelihood of a weevil infestation. Especially if you start finding weevils, buy food in smaller quantities, and use airtight containers for storage.
Regular, deep cleaning
Like your bedroom, you should also clean your kitchen regularly to keep it free of weevils, cockroaches, ants, rodents, and other pests.
Cover up wall voids and cracks
Weevils prefer dark hiding places and such holes are perfect for this purpose. Cover up holes in the walls or the furniture in your kitchen.
Although cleaning and checking your kitchen might feel like a hassle, it will take far less effort than dealing with a weevil infestation later.
How To Get Rid of Rice Weevils In The House
You now know how to prevent weevil infestations, but what if it is too late? Well, if a major infestation is already underway, follow these steps to eliminate the weevils:
Diatomaceous earth works very well against a wide variety of pests, including weevils. Take some food-grade DE and sprinkle it on the cabinet shelves after removing all the food.
Leave it that way for a couple of days, after which you can vacuum the DE and continue using the shelves again.
If you’d prefer an organic solution against weevils, bay leaves can also act as a weevil deterrent.
Hanging bay leaves in your pantry or placing them in packages of stored grains can help repel weevils.
You may even place them under your pillow or the bed sheet to keep your bed free of weevils.
Setting up weevil traps in your home can help you capture and eliminate these bugs in large numbers.
These sticky traps use pheromones to attract weevils, who then fly into the trap and get stuck in the glue. You can place the trap in strategic positions near your pantry cupboards.
Once they fill up with weevils, you can replace them with new traps.
Neem Oil & Other Organic Methods
Essential oils extracted from certain plants are good ways to control weevils organically too.
You can dilute neem oil with water and spray the solution on weevil-infested areas. Wipe your cabinet shelves clean with neem oil while cleaning.
A 50-50 mixture of vinegar and eucalyptus oil can deliver amazing results and kill weevils quickly.
When cleaning your pantry, you may also use soapy water to wash and wipe storage cabinets to repel those pesky weevils.
Soapy water is toxic and deadly to adult weevils because it corrodes their hard exoskeleton.
If you find a corner or a wall crevice where the bugs have holed up, you can spray some soapy water in there to kill them. It will be especially effective if you use warm water.
Chemical insecticides should always be a last resort, especially if you’re dealing with house pests. However, if you’re dealing with a heavy weevil infestation and your kitchen is overrun with these bugs, you may not have much choice.
All you can do is stick to non-toxic insecticides to eliminate the chances of accidentally poisoning food ingredients or inhaling toxic chemicals.
Remember, you should use chemical insecticides only if there’s a huge number of weevils and other methods aren’t working.
How To Get Rid Of Weevils In The Bathroom?
Although finding a weevil infestation in your bathroom might seem even weirder than finding these bugs in the bedroom, it does happen.
Sometimes, weevils hole up in the bathroom to overwinter during the cold months, as the bathroom offers a relatively undisturbed, dark, and damp environment.
In summer, weevils infest bathrooms to take shelter from the heat. Here’s how you can get rid of weevils in the bathroom:
- Cleaning: Like when dealing with weevil infestations in the kitchen, cleaning the bathroom is the most important step. Vacuum up the bugs, empty the bin and remove weevil-infested plants.
- Organic solution: Use a solution of vinegar and water when cleaning the bathroom to kill or repel weevils.
- Soapy water: Create a warm soapy water mixture and spray it on the weevils in your bathroom. Insecticidal soap can deliver even better results.
Besides these, you may also make use of previously discussed solutions like DE, glue traps, and pesticides.
As long as there’s dry food in your pantry, you can’t rule out the risk of a weevil infestation. As these bugs are sometimes present even in sealed packets of food, they can easily make it to your pantry.
If they have a food source, they can thrive and multiply fast. However, as long as you follow the tips we have listed in this article, you can end the infestation before it gets out of hand.
Make sure to always deep clean your kitchen, bedroom, and bathroom regularly, as that is the best defense against these pests.

Weevils in the bedroom are a common problem and its no surprise that lots of our readers have written to us about this specific problem.
Please go through some of these letters below, and some of the solutions that were adopted.
Letter 1 – Weevil from Cyprus
Unknown insect from Cyprus
I came across your site accidentally after seeing what I thought was a humming bird in my back garden, an unusual event for the south west of England. However, it turned out to be a hummingbird hawkmoth from the Mediterranean that had got lost. It doesn’t look like the ones I found on your site. Anyway, whilst on holiday in Cyprus in May of this year and keen to try out my new Cybershot camera, I came across this creature on my balcony. Of all the insects there, I never saw the like of it again and would be grateful to find out what it is and am hoping it goes by the name of ‘anteater beetle’! (I’ve got higher res images if needed)
This is some species of Weevil. Weevils belong to a very large family of beetles. They are also called Billbugs.
Update from Eric Eaton: “I actually recognize that weevil from Cyprus. It is in the genus Lixus. Many species in that genus have the yellow, powdery “bloom” on their bodies. Eric “
Letter 2 – Costa Rican Bottlebrush Weevil
Costa Rican beetle
Mon, Feb 9, 2009 at 12:57 PM
We were in Costa Rica this January, and found this beetle on the floor of the patio one evening. I’d estimate it was 4 or 5 inches long. The people we were staying with hadn’t seen anything like it before. I’m curious what type of beetle it is, and if the orange “fuzz” on it is part of the beetle, or some sort of pollen or fungal infection.
Costa Rica (Central Pacific)
We haven’t the time at the moment to identify the species, but this is a Weevil. We are relatively certain we have identified this species in the past and it is in our Weevil archives. The fuzz is a characteristic of the weevil, and is neither pollen nor fungus.
Thanks so much for your response! I did look through the archive before writing, but missed the “earlier posts” link. It is in there, and it looks like it’s a Bottlebrush Weevil ( Rhinostomus barbirostris) .
Thanks for doing our research Dawn. We were certain we had identified it once before.
You are quite right, this weevil has appeared on WTB before, in fact it has been posted at least twice (Jordan from Costa Rica – 12 March 2007; Lisa from Panama – 02 May 2006). It was previously identified as the ‘Bottlebrush Weevil’ (Rhinostomus barbirostris) and the Cuban Weevil (Rhina oblita). To clarify (or perhaps confuse) Rhinostomus barbirostris was formerly Rhina barbirostris, and Rhina oblita has been changed to Rhinostomus oblitus. They both look quite similar but their distributions are different. The reported distribution for R. oblitus is Cuba, Hispaniola, the Bahamas and perhaps Mexico and Brazil. R. barbirostris occurs in southern Mexico, Central America and most of South America. Based on that, I suggest it is probably R. barbirostris, the Bottlebrush Weevil. Both species feed on a variety of palms but are not considered a pest because they tend to target old or otherwise stressed trees. Regards.
Letter 3 – Blue Weevil from Brazil is Polyteles coelestina
Fri, Feb 13, 2009 at 10:32 AM
This impressive colorful bug was found in a park , near home, where a i use to make some shots of bugs.. Lokkas a weevil, any could say more?
Thanks a lot
We believe we have received an image of this gorgeous blue Weevil from Brazil at least once before, but we were not successful in properly identifying it. We do know that it is a Weevil, a type of Beetle. Hopefully, one of our readers will be able to assist us in a proper identification.
Actually the Weevil we posted in January 2008 is a very different Blue Species.
Update: Unknown Blue Weevil from Brazil
Tue, Feb 24, 2009 at 9:22 AM
You would think that such a striking creature would be relatively easy to track down – but not so. The weevils are a truly enormous and diverse family of coleopterans and, as often happens in taxonomy, the position and naming of this one has changed a bewildering number of times. Thanks to several wonderfully descriptive accounts from the 1800s, the golden age of bug collection, I was able to follow a trail forward that led to the modern genus Ericydeus (Curculionidae : Polydrosinae: Naupactini). There are approximately 16 species in the genus, 2 from North America and the rest from Central and South America. I believe Brutamorte’s weevil is E. sedecimpunctatus, based on early descriptions and reported distribution (throughout central Brazil), but I can’t be certain. The link provided is for a closely related species, E. schonherri; a specimen collected in French Guyana. Regards.
Update from Karl
August 6, 2009
Catching up on weevils (3 in 1 – sorry about that)
The first part of this is just FYI – a great internet resource. I found a little time to go back and catch up on some wonderful weevils that caught my attention as they were posted. One of my favorite resources for this sort of thing is the digitized version of the Biologia Centrali-Americana (58 volumes!). It is a little difficult to navigate through, but what an incredible storehouse of information! The volumes on insects were originally produced between 1879-1915, but they still stand up as an incredible body of work. The two Costa Rican weevils were identified from this site. Cheers. K
Re: Unknown Blue Weevil from Brazil (Brilliant) – Feb 13, 2009
I didn’t plan to revisit this one, but I have another update (or perhaps and alternate identification). I stumbled upon this image of a weevil specimen from the Natural History Museum in Vienna and it appears to be the very same as the one posted by Brutamonte. The name is given as Polyteles coelestina (Curculionidae: Entiminae). Unfortunately, I was unable to find any more information about it and I am not fully convinced that the identification is correct. It certainly wouldn’t be the first time that an old museum specimen was misidentified. Regards.
Letter 4 – Weevils
I have tiny black bugs that are crawling into my dog’s water bowl
January 21, 2010
I found a black bug on the counter one day, and then one on another counter, but ever since, they are not on counters but on the floor near my dog’s water bowl, and they keep crawling into her water. I took the bug to a professional who said it was a weevil, but I haven’t found any bugs in my food, and they are in her water every day, so I’m not sure what I have and how to get rid of it. I bought traps for the weevils, but so far they aren’t attracting them. The only bugs in the trap are the ones that I have put there.
The professional is correct. These are Weevils. Try checking your dogs bargain size pet food, or perhaps you have some birdseed stored nearby. Both are likely sources for the infestation.
Letter 5 – Prong Tailed Weevil from South Africa
I need my bug identified
Location: Johannesburg, South Africa
January 21, 2011 11:39 am
I found this bug today, the 21st of January, in my garden. I would like to know what bug this is and what it eats, please.
We are experiencing summer here in South Africa and I live on the highveld in Johannesburg.
I have included three of my best photos of my bug.
Thanks very much
This is some species of Weevil, but we are uncertain of its exact identity. Weevils belong to a large family of Beetles and many of them are characterized by a long snout which gives them a comical appearance. Many Weevils are considered agricultural pests of various crops and other Weevils will infest stored foods. We will continue to try to identify this species.
Update: December 15, 2016
Thanks to a comment from Ben23, we now know that this is most likely a Prong Tailed Weevil, Bronchus furvus, a species documented from South Africa on iSpot.
Letter 6 – Colorful Weevil from Indonesia
Beautiful Creature – Indonesia
Location: Somewhere in Indonesia (jungle)
September 8, 2011 10:17 pm
I have a friend visiting the jungle area of Indonesia. He took this picture of an insect – I consider it to be a beautiful yet odd looking but in an awesome way type of insect. Can you help identify it? He almost looks like he could be clay-mation.
While we haven’t the time to research what we believe will not be too difficult of a species identification, we are immediately posting your photo of this magnificent, colorful, Indonesian Weevil. Just prior to hitting post, we decided to see if we could identify this beauty, and we quickly found the appropriately named Eupholus magnificus on InsectaCulture.com.
Letter 7 – Weevil mistaken for Bed Bug
Subject: What is this thing?
Location: West Central Florida
May 25, 2013 8:28 pm
I am almost 60 years old and I have never seen a Bed Bug.
Today, I found a bug crawling across my mattress. At first it looked like a tick but after closer inspection I was pretty sure it was not a tick.
I put the bug in one of many RX vials I have, and when I went to a home and garden center, I showed the bug to a few folks who claim to know a good deal about insects. One person said it was a Wood Beetle, but I can’t find a photo of a Wood Beetle that looks anything like this bug. Another person told me it is some kind of Beetle although they didn’t know what kind. All 3 folks assured me it is not a Bed Bug, although when I look up various insects, it looks closer to a Bed Bug than any other bug I can find.
My local Pest General Store, who I hope can identify this right away, isn’t open again until Tuesday, because of the Memorial Day holiday.
I turned the room upside down, including both mattresses. I looked with a bright light and reading glasses and couldn’t find any of the signs of Bed Bugs that you would expect to see with an infestation, as a matter of fact, I couldn’t find a bug, an egg, any blood, any stains, or anything else that you might expect from what I have read.
I took all the bedding and hot washed and hot dried all of it. I want to sleep in my bed, but I’m not sure I’m going back in there until I find out if it is a Bed Bug or not, and if so, until they are gone.
There is one thing odd about this bug, that I was not able to see in any internet photos of Bed Bugs. Even though my photos are through an amber colored prescription vial, the oddity shows up very well. Instead of the antennae coming out of the head, they appear to be coming out of a seventh leg or pointer in the front of the bug.
The bug is approx. 2-3 mm in length and dark brown. I am color blind, but my wife tells me that she sees little to no red in the color.
Please take a look at these two photos for me and tell me what you think. I would really like to go back to my bedroom.
I thank you, in advance, for your help.
Signature: what does this mean?
Though we are responding to you quickly, your submission will not go live on our site until next week since we will be away from the office and we postdate submissions so there is a daily updating of our site. This is not a Bed Bug. It is some species of Weevil or Snout Beetle. Many Weevils are agricultural pests and some species infest stored products in the home, however they pose no threat to humans, pets or home furnishings.
Letter 8 – Palm Weevil from Dominican Republic
Subject: Found Bug
Location: Santo Domingo, Dominican Republic
June 1, 2014 3:26 pm
Warm greetings from the Dominican Republic. I found this curious bug resting on the wall of one of the stairs of the building where I live. I was wondering if this is a beneficial insect or a pest.
Thanks in advance for your support.
This is a Weevil or Snout Beetle, and we have been searching the internet for a spell trying to identify it to the genus or species level. We did find a close match on FlickR that was imaged in Brazil, but it is not identified. We will continue searching.
Many thanks for your kind support. Thanks to your information i could investigate that the classification of the Curculionidae species is very extensive.
Have a good week.
Hi Daniel and Alejandro:
It looks like the Palm Weevil, Rhinostomus scrutator (Curculionidae: Dryophthorinae: Rhinostomini). According to Vaurie (1970) its distribution is limited to the Dominican half of Hispanola. Also: “The species on which there is some biological information (barbirostris, niger, oblitus, and scrutator) live at the expense of palms, notably the coconut palm (Palmaceae or Arecaceae). The adults, which are nocturnal, generally attack only damaged, fallen, or decomposing trunks. The larvae bore within and pupate near the outer bark. (See the species for further details). These weevils are not found on other Caribbean islands that have palm trees, perhaps because the other islands are too small.” Regards. Karl
Thanks so much for doing the research on this Karl.
Letter 9 – Weevils Invade Hawaii at Night
Subject: Night invasion of beetles
Location: maui, Hawaii
November 13, 2014 10:50 pm
Aloha from Maui,
We’ve had intermittent rain this year and each time we get invaded by these peculiar beetles within a week. They are attracted to light and will make their way through our screens. Turning on the light outside reveals dozens on the screen. We haven’t been bit by them that we know. They are annoying and will land on us while watching TV.
I searched the internet and the closest identification might be “Triatomine nymphal instal” but I can’t be certain as the shape doesn’t seem exact.
They have 6 legs and can fly.
Signature: Michelle in Maui
This is not a Blood Sucking Conenose Bug, also known as a Kissing Bug in the genus Triatoma, that you can read about on the Kiss of Death page, but rather a Weevil, a member of the family Curculionidae, that is well represented on BugGuide. You do not need to worry about getting bitten by a Weevil. Many Weevils are agricultural pests and they can proliferate in areas where their food plant is commercially grown.
What a relief! I didn’t think they were Blood-Sucking Conenose bugs but they do look a little like it. Being that they haven’t bitten us I had my doubts.
Funny that a common weevil inundates us each year after rains. Last night it was breezy with rain and we had minimal invasion. Perhaps they can’t fly in the rain?
Either way, thank you so much for the identification and the link to Bug Guide. It was a very interesting read!
Letter 10 – Desert Weevil found in Joshua Tree is from genus Ophryastes
Subject: Bug found at Joshua Tree Nat Park
Geographic location of the bug: Joshua Tree National Park
Time: 12:19 AM EDT
Your letter to the bugman: Hello, I found this little guy/gal on March 17, 2019 at Joshua Tree National Park in Southern California. Do you know what it is? Thank you, Deb
How you want your letter signed: deb
This is some species of Weevil, but we do not recognize it. Can you please provide an approximate size and any other helpful information. Was it found on a plant? What type of plant? Often, knowing the food preferences is a big assistance with identifications.
Thank you for replying.
Ah-ha! I thought it might be some sort of a weevil! J
I am sorry, I thought I sent you the photo of it with my finger in the photo so you could see its size in relationship to my finger.
Attached is the photo of it with my thumb in the photo. It is about the size of my thumb nail.
It was not found on a plant.
I found it March 17, 2019, on the roadway, under my solar panels in La Quinta, CA behind the Torre Nissan dealership (address: 2069 79125, CA-111, La Quinta, CA 92253)
I don’t know if this is relevant or not to its origin:
- Just prior to finding it, I was out camping at Joshua Tree National Park in California from March 7, 2019 – March 16, 2019.
- I stayed at Belle campground in the park.
- The park was in full bloom.
- When leaving the park on March 16, 2019, I had vehicle problems and was towed to Torre Nissan dealership (address: 2069 79125, CA-111, La Quinta, CA 92253)
- While waiting for my truck to be repaired, I parked my travel trailer behind the Nissan dealership.
- I put out my solar panels on the roadway so I would have electricity while I waited.
- The next day, on March 17, 2019, my truck repairs were done and I went to pack up my solar panels and this little guy was on the ground under my panels.
- I can’t be sure that he stowed away in my solar panels or that I carried him from Joshua Tree National Park to La Quinta, CA.
- All I can say is that it was on the roadway, under my solar panels, in La Quinta, CA behind the Torre Nissan dealership (address: 2069 79125, CA-111, La Quinta, CA 92253)
Thank you for your help.
I posted it on my Facebook page and everyone was interested in knowing what this strange creature was.
I did a little research on the internet and I thought it might be a weevil of some sort.
