Rice weevils are a common pest known to infest stored grains, seeds, and grain products.
Measuring about 1/8 inch long, these reddish-brown insects have distinct snouts and markings on their wing covers, making them easily identifiable.
While their presence may be worrisome, it’s important to understand the potential harm they can cause.
Although rice weevils are primarily considered a nuisance, their infestation can result in significant damage to food supplies.
They lay their eggs in grains, and as the larvae grow, they consume the grain from the inside.
As the infestation grows, the quality of the grain diminishes, leading to economic losses in the agricultural and food industries.
There are several ways to manage rice weevil infestations, such as using pesticides or employing natural control methods.
Knowing the extent of the harm these pests can cause helps in making informed decisions on suitable prevention and control measures.
Overview of Rice Weevils
Rice weevils are small insects found commonly in stored grain products. Adults are approximately 1/8 inch long and have a reddish-brown to black color.
They are distinguishable by their distinct snout and four light reddish or yellowish spots found on their wing covers.
- Eggs are laid inside grain kernels by female weevils.
- Larvae emerge within the kernel and feed on it.
- The pupation stage occurs inside the kernel.
- Adult weevils break free of the kernel and continue the cycle.
Differences between Rice Weevils and Other Weevils
A few notable weevils are the rice weevil, granary weevil, and maize weevil. They have minor differences, as shown below:
|Feature||Rice Weevil||Granary Weevil||Maize Weevil|
|Size||1/8 inch (2-3 mm)||3/16 inch (4.8 mm)||Similar to Rice Weevil|
|Color||Reddish-brown to black with 4 reddish-yellowish spots||Black-brown or red-brown||Similar to Rice Weevil|
|Thorax||Round or irregularly shaped pits||Longitudinal punctures||Similar to Rice Weevil|
|Ability to Fly||Yes||No||Yes|
Rice weevils can cause damage to stored grains, but they usually do not harm humans or pets.
Proper storage techniques can help prevent infestations from these pests.
Are Rice Weevils Harmful?
Impact on Agriculture
- Rice weevils are an important pest of stored grain crops worldwide.
- They can cause significant damage to agricultural products, harming farmers’ livelihoods.
- Rice weevils infest rice, wheat, corn, and other stored grains.
- They consume these grains, leading to a decrease in crop yield.
Effects on Stored Grains and Pantry Items
- Infestations of rice weevils can lead to losses in stored grains and pantry items.
- Their reproduction cycle is quick: in warm weather, they can complete their life stages in just 26 days.
Pros and cons of rice weevils:
- None: they are harmful pests with no known benefits.
- They cause damage to stored grains.
- They can infest pantry items and spread to other food storage areas.
Comparison table of rice weevils, granary weevils, and maize weevils:
|Weevil Species||Host Crops||Flying Ability||Attraction to Light|
|Rice Weevil||Rice, wheat, corn||Yes||Yes|
|Granary Weevil||Wheat, rice, corn||No||No|
|Maize Weevil||Corn, rice, wheat||Yes||Yes|
Characteristics of rice weevils:
- Adults are 1/8″ long.
- They have a distinct snout.
- Dull reddish-brown color with 4 faint reddish-yellow marks on wing covers.
- Attracted to light.
- Can fly.
- Larvae are legless and creamy-white.
Remember, rice weevils are harmful pests that can cause damage to both agriculture and stored grains in your pantry.
Be sure to take preventive measures and address any infestations promptly to minimize their impact.
How to Detect and Control Rice Weevil Infestations
Rice weevils are small pests that can infest stored grains and become pantry pests.
They’re approximately 1/8 inch long and have a distinct snout. Detecting their presence can be done by closely examining your stored grains for signs of damage or adult weevils.
Methods of Control
There are several ways to control and get rid of rice weevil infestations:
- Heat treatment: Placing infested grains in an oven at 140°F for 15 minutes or a microwave on high for 5 minutes can kill the weevils.
- Freezing: Storing grains in the freezer at 0°F for at least four days can also be effective.
- Clean and vacuum: Regularly cleaning your pantry and vacuuming shelves can help remove any stray weevils.
- Airtight containers: Storing grains in airtight containers can prevent weevils from infesting them.
Pros and Cons of Control Methods
|Heat treatment||Quick and effective||May alter the texture of grains|
|Freezing||Effective and safe||Requires significant freezer space|
|Cleaning/vacuum||Maintains a clean pantry environment||Time-consuming, not a guarantee|
|Airtight containers||Prevents infestations||Initial investment in containers|
- Rice weevils can infest stored grains and become pantry pests.
- Detection involves examining grains for damage or adult weevils.
- Control methods include heat, freezing, cleaning, and airtight containers.
- Each control method has its pros and cons, making it crucial to choose the most suitable approach for your situation.
Managing rice weevil infestations is essential to protect your pantry and stored grains.
Regular inspections and preventative measures like airtight containers can go a long way in avoiding these pesky pests.
Preventing Future Infestations
Preventing rice weevil infestations involves proper storage and cleanliness. Let’s discuss some steps to help keep these pests at bay.
Store rice: Always store rice in tightly sealed containers. Glass or thick plastic containers are ideal for preventing weevils from reaching your rice1.
Packaging: When purchasing rice, look for quality packaging that is not damaged. Damaged packaging may allow weevils to access the rice2.
Cleaning: Regularly clean pantry shelves to remove any residue or hidden insects3. This discourages weevil infestations.
Bay leaves: Adding a few bay leaves to your rice container4 may act as a natural repellent. Weevils are said to dislike the aroma of bay leaves.
Here is a comparison table to highlight the differences between various prevention methods:
|Sealed containers||Keeps rice weevil-free||May need to purchase containers|
|Quality packaging||Ensures rice is free from weevils||Limited control over packaging|
|Cleaning shelves||Maintains a clean environment for storage||Requires regular effort|
|Bay leaves||Natural repellent||Effectiveness may vary|
Consider following these simple steps to help protect your rice from weevil infestations and maintain a clean pantry environment.
Rice weevils (Sitophilus oryzae) are small insects with:
- A distinct snout
- Dull reddish-brown color
- Four faint reddish to yellowish marks on their wings
- The ability to fly and be attracted to light1
These pests belong to the Curculionidae family and are known to infest various grains, seeds, and beans.
They’re cousins to the maize weevil (Sitophilus zeamais) and granary weevil (Sitophilus granarius)4.
Adult rice weevils are equipped with strong mandibles that allow them to bore into seeds, cereals, and nuts1.
Female weevils lay their eggs inside these food sources, and as larvae hatch, they feed and develop within the kernels5.
Here are some key differences between rice weevils and their relatives:
|Feature||Rice Weevil||Maize Weevil||Granary Weevil|
|Size||1/8 inch||Similar to rice weevil||Slightly larger (3/16 inch)|
|Color||Reddish-brown||Similar to rice weevil||Black-brown, occasionally red-brown2|
Rice weevils are not known to transmit diseases, but their infestation can cause significant product damage and loss in the food processing industry.
It’s essential to maintain proper storage conditions to prevent infestations. Some precautionary measures include:
- Washing and drying rice and other grains before storage
- Storing food items in airtight containers
- Regularly cleaning storage areas
- Disposing of infested materials
In case of a rice weevil infestation, you can:
- Freeze the infested items for at least 4 days3
- Boil the grains to kill the weevils and their eggs
- Throw away heavily infested products to prevent the spread
Rice weevils could invade garden soil, pet food, or other food sources, so it’s crucial to monitor these areas and act promptly in case of an infestation1.
Rice weevils are small beetles that infest stored grains, such as rice, wheat, corn, and oats. They are not harmful to humans or animals, but they can cause significant economic losses and reduce the quality of food.
Rice weevils can be identified by their reddish-brown color, elongated snout, and four light spots on their wing covers. They can also fly and produce a squeaking sound when disturbed.
Rice weevils can be prevented by using sealed containers, inspecting grains before purchase, and freezing or heating infested grains.
Rice weevils are not easy to eradicate, but they can be controlled by using traps, insecticides, or biological agents.
Rice weevils are one of the most common and widespread pests of stored grains, and require constant vigilance and management.

Letter 1 – Grain Weevil
tiny black bugs
Fri, Jan 2, 2009 at 10:43 PM
These bugs recently appeared in a house that we have been living in for the past 11 months. We have seen them in the washer and dryer room and our bathroom. They are mostly seen crawling on walls.
We use a quarterly pest control service and the last time they came they sprayed in the attic. I am calling them to come back for a “call back” but I was hoping to know what they are sooner.
Thanks, bugged out in Texas
Dear Bugged Out in Texas,
This is a weevil, possibly a grain weevil. Is there stored pet food nearby?
Thanks for the quick response. The pest control (Truly Nolen) is here and you “nailed it”! It is a weevil. He showed us a book with insects and to be exact it is a rice weevil.
They were infested in a bag of bird seed that we have in a cabinet in our dining room. The bag contains milo, millet, cracked corn and sunflower seeds. The corn is what it looks like it was after.
The strange thing is that we have had the plastic bag of seed since the summer and never noticed them until we came back from my grandparents house in Oklahoma.
We brought back a back of nuts and had them in the same cabinet. Two days later we noticed the bugs. Not sure if that is it but we can draw a pretty good conclusion that is were they came from.
WE can’t thank you enough for helping identify these pesky things! I’ve included a link that shows what they look like in our bird seed.
Have a Happy New Year!

Is this a springtail?
Location: Baltimore, MD
January 2, 2011 8:30 pm
I keep finding a bunch of seemingly dead bugs just inside my basement door this winter. They are black and tiny –initially I thought it was mouse poop until I got very close.
Tonight, I was sweeping them up again, and realized some of them were NOT dead. They look a lot like springtails, but the live ones I saw did not jump, and do not appear to have round heads like in the picture on your site.
We are trying to sell the house, so any info is much appreciated!
Signature: Kevin in Baltimore
You have Grain Weevils, not Springtails. You may have some stored bird seed or pet food, or possibly a bag of rice in the vicinity that has been infested.

Hi, I found a few hundred in my basement fairly near each other. They are small about 3-8 millimeters each, under a loop they have a rounded body, but the curious thing is the ”tube” coming from the head.
They also have wings. Any help on what it is and how to prevent more from appearing besides cleaning very frequently. Thanks for any help.
You have an infestation of Grain Weevils. You should check stored grain products in your basement, like bargain quantities of bird seed, pet food or rice to track down the source of the infestation.

My girlfriend and I moved in to our apartment in east york ontario 3 months ago. Immediately we started noticing ants and after about 2 months started noticing few of these little guys.
To me it looks like a weevil but I’d like to be sure. Also, do they bite?
Signature: Thanks, Toothbrush
This is a Weevil and they do not bite. They do infest stored grain products. Try checking the rice in the pantry and we frequently get responses that they have infested stored bird seed.

Please help, my husband’s niece house sit for us & the next day after being home we found all these little bugs on top of the bed. We thought they were baby dog ticks round & black grey in color.
We vacuumed them up & stripped the bed. The next day we came home to them on the bed again & I went into overdrive cleaning, even encased our bed. I have bites on my, neck, shoulders & around hairline. My husband & daughter have no signs….I. have checked our heads for lice & nothing!!
I am losing my mind over this & getting tired of our nightly ritual of bed cleaning. We live in southern Maryland. I am also submitting a pic of a black bug we have seen a lot of, that bug is upside down in the pic….thank you!!
Signature: desperately need help
Dear desperately need help,
We cannot make out any details in the thing you found on the bed. Did they move? Are you certain they were living things?
We sometimes get reports of Tropical Fowl Mites or Tropical Rat Mites entering homes and biting the occupants, but this generally happens if there was a bird nest on the roof or a rat’s nest the attic, and the occupants “flew the coop”, leaving nothing else for the Mites to feed upon. Again, we cannot make out any details in your photo to be certain.
Here is a link to Biting Mites in the home from CityBugs website. The second creature is a Grain Weevil, and it may be infesting stored grain products in the pantry or pet foods including bird seed. You will need to find the source of the infestation to eliminate that problem. Just discard the infested food products. Here is a recent posting on Grain Weevils.

Thank you for responding so quickly! The weivels are an easy fix. The bugs found on bed were alive. At first glance it looked like dirt & then I did think were dead….but they moved very slowly.
Sort of just pulling themselves along with their very tiny (many) legs. I took a couple of more pics, hope they help. Also the one in the pic seems to be dried up kind of shriveled…probably from one the many products I used. However my itching has not subsided. Thank you again!

Bug Identification !
I’m Heather from Southern California, I recently have been finding lots of bugs all over my tiles and carpet area… They crawl really slow, and when touched or blown agaisnt , tuck there legs in.
The pictures that i took are of the bugs on a 12inx12in tiles. If you could help me identify the bugs and let me know where they came from that would be great!
THANK YOU VERY MUCH!
This is a Grain Weevil, a type of Pantry Beetle. We are guessing they are infesting some stored food, possibly pet food or other flour product in your kitchen.
Letter 8 – Grain Weevil
Found in Dried Noodles with mold!
This was the most descusting thing that Ive seen in quite a while. I was grabing a ramen and noticed a mold bag of noddles that had previously been opened.
I took a second look and about One Hundred of these tiny little bugs where cralling and falling out of the bag! What are they and How can I get rid of them.
P.S. I decided NOT to eat the ramen.
You found Grain Weevils in your Ramen. They are a type of Pantry Beetle easily identified by the snout. Obviously a female beetle got into the bag and layed eggs. This is just one reason there is an expiration date on foods.

Tiny Black Bug pics on a dime…
Great website, wonderfull resource! We just moved into a house this week I have no idea what these are, but I found about 10 of them around my window this morning lying around barely moving.
Hope you can help,
This appears to be some species of Grain Weevil, a type of Pantry Beetle. They infest stored grain products. It is possible they were somehow left behind when the previous tenant vacated. Without a food source, they are trying to get outside and are dying.

These are Grain Weevils, and you need to locate the source of the infestation. Start with rice in the pantry or that big bag of bird seed you have stored somewhere. They will also infest bargain bags of pet food.
Thanks for your prompt reply! I will get right on the case and see if we have any of those items you mentioned lying around loose. I will also lace the areas with a residual insecticide. Thanks again for your prompt service.

Letter 13 – Grain Weevils
Hello, I live in Saskatchewan, Canada and have found 40-50 beetles in my house in the past two weeks. They are everywhere … upstairs, downstairs, bathrooms, kitchen, bedrooms, etc, etc. They are approximately 1/4 inch (5-6 mm) in length and solid black.
We’ve never seen them fly and believe that they don’t have wings. I’ve included pictures. I found one larva. It was redish-brown and appeared striped (very similar to that of a larder beetle).
Can you help us identify them, tell us why they’re moving in, and how to get rid of them. Thank you so much for any help you can offer.
You have one of the Grain Weevils. This is just one type of Pantry Beetle. Grain Weevils infest stored grain products. Weevils belong to the Family Curculionidae.
Letter 14 – Grain Weevils
Pointed head bug
Perhaps you can identify this bug picture I sketched. I cannot find a close match anywhere to say that I am sure what it is. It is a 6 legged bug VERY tiny, about 1/10″. I can tell you that not only did they show up in my kitchen, but there were literally millions in a bag of birdseed!
There were so many that you could hear the bag rustling. Gross! I looked in the bag to see millions of these creatures with their pointed heads and antennae. I hope you could steer me as to what these bugs are.
Weevils are one type of Pantry Beetle whose shape matches your description and drawing. Weevils are a type of beetle belonging to the family Curculionidae. Grain Weevils belong to the genus Sitophilus and have the head elongated into a snout.

Letter 16 – Grain Weevil
Please help to identify bugs
We have what seems like a million of these little black bugs, primarily in our finished basement. They are tiny – you can see next to the penny a comparison- but less than 1/8 inch.
There are tons of them, though. We find them dead and alive. They have six legs, two antennae and a long, skinny nose/snout thing. They are semi-hard, but not so much that you can’t squeeze them. They are on the carpet (berber) and sometimes on the linoleum and concrete.
Our basement is semi-underground. Meaning, if you look out the windows, the ground is a littler higher than waist level. We live in Maryland, so you can get an idea of climate/geography.
Please help! We don’t know if they’re good, bad or indifferent. Thanks so much.
(Do we check your website for a reply or will you send it here? Thanks!!!)
We try to answer as many letters as possible. We post on the site and respond directly. You have some species of Grain Weevil, Sitophilus species. They are very small and the larvae, which do the damage in stored grains, are obese pale grubs without obvious legs.
Letter 17 – Sweet Potato Weevil from Hawaii
A Sweet Potato Weevil?
Sat, Dec 6, 2008 at 7:15 PM
About a week ago I threw an old sweet potato into the yard. Today I went to move the sweet potato to a garden area just in case it was going to grow and I found some odd little red and black insects collected underneath it.
The bugs were a little less than a centimeter long and they had black heads and abdomens with thoraxes that looked as if it was made of two red spheres. Their heads had a long black snout with antennae at the end of the snout. When anything touched them they dropped to their sides as if they were dead and a minute later they would revive themselves and move around again.
They also pulled in their antennae when they played dead. I browsed through insect images online and I think they might be sweet potato weevils but I’m not entirely sure.
That bug in the photo was the only one that remained on the sweet potato when I moved it, the rest fell off playing dead.
Thank you for your time reading this! And pest or not, they all were left unharmed after the potato was moved.
You are absolutely correct. This is a Sweet Potato Weevil, Cylas formicarius. It is a perfect match to images posted to BugGuide which states: “Range Worldwide (mostly tropical and subtropical).
Introduced in North America, where found from South Carolina to Florida, west to Texas” and “Larvae bore in sweet potatoes. Tiny white eggs are laid in punctures made in vines near ground, or even in stored potatoes.
Larvae burrow in and feed for 2-3 weeks, then pupate in a burrow (2). Also attacks morning-glories and some Asteraceae.”
Thank you so much for the identification! I am one insect identification smarter now 🙂 My neighbors recently dug up all of their sweet potato plants so perhaps they wandered from there to my yard looking for food.
I didn’t know these weevils existed until I saw them under the sweet potato, it’s amazing how insects have their own little niches in unexpected places. Thank you again for the identification!
Letter 18 – Grain Weevils and Hypersensitivity Pneumonitis
March 2, 2010
I was shocked to read repeatedly on your site that bugs called grain weevils are not harmful to humans. If you did the proper research, you would find that inhalation of dust from the grain weevil causes a serious illness in humans called hypersensitivity pneumonitis, which results in pulmonary fibrosis and is FATAL.
I know this because I have this illness, which I contracted from an infestation of grain weevils from a box of dry pet food. If you look up hypersensitivity pneumonitis in any medical textbook, you will find that Miller’s Lung, caused by the grain weevil, is one of the causes of this fatal disease.
Dear Goldy G.
We will research this condition and link to findings on the web. Here is what we found upon researching Miller’s Lung.

It is a tiny black bug (less than cenitimeter) that looks simliary to an Emperor Beetle. They are numerous and come out from under the stove and stairs. Exterminator did not know what it was.
Signature: What does this mean?
I figured it out. It was a weevil. No need for your assistance. Thank you,
The signature on our form is the place you put the name you would like to be posted with your letter. Some people provide their entire given name, and others prefer to sign with initials. Some of our readers provide a clever moniker in that field. You do have an infestation, but we would strongly urge you not to hire an exterminator.
You have Grain Weevils, and you need to find the source of the infestation. Tenting your home will not help with this problem. Grain Weevils often infest birdseed, and pet food, so if you have bargain size items that you have not used up in a timely manner, the Grain Weevils may be reproducing there.
They will also infest a wide variety of stored grain products, including big bags of rice. Check the pantry thoroughly. Once you find the food source and eliminate it, things should be fine.
Food products often have an expiration date, and at least once a year, you should make an effort to remove old boxes of cookies and crackers and similar items from the kitchen shelves.

I keep finding these little guys around my apartment. Started showing up about two weeks ago once it really started getting cold, though I don’t know if that has anything to do with it.
I find one – five of them a day, usually crawling on the wall or floor. I live in a one room apartment in South Korea, so kitchen pantry, bed, and bathroom are all within reach.
I generally find the bugs near my computer desk or on the floor near the bed. As far as I can tell from googling around, they don’t look like bedbugs, but I’m starting to wonder if I should be concerned about them as I’m only finding more of them every day now.
Thanks for the help!
This is a Grain Weevil, a cosmopolitan household pest that infests stored grain products including rice, pet foods and bird seed. Search the pantry and that bargain bag of pet food for possible sources of your infestation.
Amazing! Thank you so much for the quick ID. I’ll purge the pantry ASAP. This website is fantastic!
