Epsom salt is a popular remedy for a variety of ailments, but did you know it can also be used to combat cutworms in your garden? Cutworms are the larvae of certain moth species that can cause significant damage to young plants by cutting off their stems at the base. As a result, it’s crucial to address cutworm infestations as soon as possible.
Using Epsom salt can be an effective, natural way to deter cutworms while providing essential nutrients to your plants. The magnesium content in Epsom salt not only deters cutworms but also promotes stronger plant growth, making your garden more resistant to future pests. Additionally, Epsom salt treatments are eco-friendly and pose minimal environmental risks.
To use Epsom salt against cutworms, simply dissolve one tablespoon of Epsom salt in one gallon of water, and spray the solution on the base of your plants. This method can both prevent and treat current cutworm infestations without resorting to harsh chemical pesticides. Remember, maintaining your garden’s health is essential for avoiding recurring pest problems.
Epsom Salt for Cutworms: An Overview
The Use of Epsom Salt as a Pesticide
Epsom salt, or magnesium sulfate, is a popular addition to gardens for various reasons. Here are some uses:
- Fertilizer: Contributes magnesium to the soil
- Pest control: Can be a deterrent for pests
For example, many gardeners sprinkle Epsom salt around their tomato plants to deter pests like cutworms.
Why Epsom Salt is Effective Against Cutworms
Epsom salt works against cutworms due to the following mechanisms:
- Saltiness: The taste repels insects
- Dehydration: Salt can dehydrate larvae
However, it is important to use Epsom salt sparingly, as too much can harm plants. Here’s a comparison table of using Epsom salt versus other pest control methods:
|Epsom Salt||Environmentally friendly, inexpensive||May harm plants if overused|
|Pesticides||Fast-acting, wide range of targets||Chemicals can be hazardous|
One common technique to prevent cutworm damage is to create a barrier using Epsom salt:
- Sprinkle a small amount around the base of the plant
- Reapply after heavy rains
In summary, Epsom salt can be an effective, environmentally friendly method of controlling cutworms in your garden. However, be cautious with the amount used to avoid harming your plants.
Application of Epsom Salt Solution for Cutworm Control
Epsom salt, also known as magnesium sulfate, can help in controlling cutworms. This section explains how to create and apply the Epsom salt solution to tackle these pests.
Ratio of Water and Epsom Salt
- In a gallon of water, mix 1 cup of Epsom salt.
- Stir until the Epsom salt dissolves completely in the water.
When and How to Apply Epsom Salt Solution
- Apply the solution early in the morning or late in the evening.
- Do this during the active cutworm season or when cutworm presence is observed.
- Use a garden watering can to sprinkle the solution around the base of affected plants.
- The Epsom salt solution will help repel cutworms by increasing hydrogen levels in the soil.
- Apply the Epsom salt solution every week during the cutworm season for optimal results.
- Repeat the treatment if you notice the presence of new cutworms.
Advantages of using Epsom salt solution for cutworm control:
- Repels cutworms by raising hydrogen levels in the soil
- Replenishes magnesium in the soil, which is beneficial for plant growth
Disadvantages of using Epsom salt solution for cutworm control:
- Can be washed away during heavy rains
- Might not be effective against all cutworm species
|Epsom Salt Solution||Chemical Insecticide|
|Eco-friendly||Can be harmful to the environment and beneficial insects|
|Replenishes magnesium in the soil||No added nutritional benefits|
|Needs frequent application||Longer lasting effects with fewer applications|
In conclusion, using an Epsom salt solution for cutworm control can be an eco-friendly and beneficial method for maintaining the health of your garden plants.
Epsom Salt and Plant Health
Positive Effects of Epsom Salt on Plants
- Epsom salt provides plants with magnesium, an essential nutrient for various functions like photosynthesis and seed production.
- It can improve the plants’ uptake of nutrients such as nitrogen and phosphorus from the soil, fostering overall growth.
Example: Adding Epsom salt to tomato plants may increase fruit size and yield.
Situations When Epsom Salt May Cause Harm
- Overuse: Excessive application of Epsom salt can lead to a magnesium imbalance in plants, inhibiting their ability to absorb other essential nutrients.
- Soil type: Epsom salt is not recommended for plants growing in magnesium-rich soils, as too much magnesium may cause harm.
Example: Overusing Epsom salt on potato plants may result in misshapen tubers.
|Soil Type||Epsom Salt Suitability|
Epsom Salt as a Pest Deterrent
Epsom salt has been known to deter some garden pests, including cutworms. It is:
- Safe for your plants and soil when used in moderate amounts.
- A natural alternative to chemical pesticides.
- It may not be as effective as synthetic chemical treatments.
- It won’t work on all pests, meaning integrated pest management practices are still necessary.
Epsom Salt Benefits for the Heart and Skin
Epsom salt baths have some potential health benefits:
- May help soothe sore muscles and joints.
- Improve skin hydration and reduce dry skin conditions.
Note: Always consult a healthcare professional before using Epsom salt for health purposes.
To summarize, Epsom salt can benefit the health of your plants and deter some garden pests, like cutworms, when used properly. However, it’s essential to avoid overuse and ensure the soil type is suitable for Epsom salt application.
Additional Methods for Cutworm Control
Use of Organic Treatments and Barriers
Organic treatments can help keep cutworm populations under control. Using Bacillus thuringiensis (Bt), a natural bacteria that targets specific insects, is one way how to get rid of cutworms naturally. Bt is an inexpensive and eco-friendly solution for gardening enthusiasts looking to address a cutworm infestation.
Barriers can protect vulnerable seedlings from cutworms. Placing collars made of cardboard, plastic, or aluminum foil around seedlings can help prevent cutworms from reaching them.
Attracting Natural Predators to Your Garden
In addition to barriers and organic treatments, attracting natural predators can be an efficient method for limiting cutworm populations in your garden.
Some common natural predators include:
- Ground beetles
- Soldier beetles
Encourage these predators by providing them with shelter and access to water sources. Eliminating excessive weeds can also help attract ground beetles, which are predacious on cutworms.
Keep in mind that attracting these natural predators will not only help in controlling cutworms but can also be beneficial for managing other pests, such as slugs and roaches.
Comparison Table: Organic Treatments vs. Attracting Predators
|Organic Treatments||Eco-friendly, targets specific pests, inexpensive||May require frequent reapplication|
|Attracting Predators||Addresses multiple pests, no chemicals needed||Takes time for predators to establish|
In summary, using organic treatments and barriers, along with attracting natural predators, are effective strategies for controlling cutworms in your garden. Implementing these methods can help maintain a healthy and thriving garden without relying on harmful chemical insecticides.
Preventing Future Cutworm Infestations
Proper Garden Maintenance and Clean Up
To prevent cutworms from infesting your garden, focus on regularly maintaining and cleaning up your garden space. This can include:
- Grass: Keep lawns mowed and avoid excess grass growth near your plants.
- Garden Beds: Remove any debris or fallen leaves that can provide hiding places for cutworm larvae.
- Compost: Regularly turn your compost pile to prevent cutworms from establishing in the area.
Incorporating diatomaceous earth and crushed eggshells into your soil may also deter cutworms due to their abrasive nature.
Planting Techniques to Deter Cutworms
When you’re planting your garden, there are a few techniques you can use to help keep cutworms at bay:
- Cutworm Collars: Place these around the base of your plants to prevent cutworms from reaching and cutting the stem.
- Beneficial Nematodes: Introduce these natural predators to your garden to help control cutworm populations.
- Birds: Attract birds to your garden by providing birdhouses and feeders, as they’ll help to control cutworms by eating them.
You can also try using a soapy water spray on the affected plants, as this may help to control cutworm populations.
It’s also important to consider natural alternatives for pest control, such as Essentria IC-3, which is a plant-based insecticide that targets a variety of pests, including cutworms. Here’s a comparison table of Essentria IC-3 and traditional chemical insecticides:
|Feature||Essentria IC-3||Chemical Insecticides|
|Safety||Non-toxic to humans and pets||May have harmful effects on humans and pets|
|Environmental Impact||Biodegradable and eco-friendly||May negatively impact the environment|
|Target Pests||Broad-spectrum control||May be specific to certain pests|
|Application||Can be applied through various methods (spray, fog, etc.)||May require specific application techniques|
Remember, prevention is key in managing cutworm infestations. By employing proper garden maintenance, clean-up techniques, and planting methods that deter cutworms, you can help keep your garden healthy and free from these pests.
Over the years, our website, whatsthatbug.com has received hundreds of letters and some interesting images asking us about these insects. Scroll down to have a look at some of them.
Letter 1 – Smartweed Caterpillar
Name this Catapillar
My Dad and I was out looking at the fall leaves and spotted this catapillar, its very showy can you name it for me. My Dad and I were in the southwest part of Arkansas, Dequeen. Thanks for your help.
Thanks for writing back with your location. We have been obsessed with properly identifying your distinctive caterpillar. It is a Smartweed Caterpillar, the larval form of the Smeared Dagger Moth, Acronicta oblinita. It is a highly variable caterpillar, but there is a near perfect match posted on BugGuide.
Letter 2 – Lily Moth Caterpillar from India
Subject: Caterpillar type Worm
Geographic location of the bug: New delhi , india
Time: 10:35 AM EDT
It was found on road near garden
How you want your letter signed: Vipul
We started to research your request by searching for colorful caterpillars in India, and we quickly found the Lily Moth Caterpillar, Polytela gloriosae, on Project Noah. We then pursued that information to the Insects in Indian Agroecosystems site where it states: “Feeds mainly on Liliaceae and Amaryllidaceae. Known hosts from India include Amaryllis sp., Gloriosa superba, Crinum asiaticum, Lilium sp., and Zephyranthes sp.”
Letter 3 – Laugher spins Cocoon in Georgia
Subject: The laugher
Location: Palmetto, Georgia
November 12, 2013 5:37 pm
I found a fuzzy white caterpillar, around mid-October, which I later researched and identified as ”The Laugher Moth”. I found it near an oak tree in my front yard, and found out that oak is what it feeds off of. I put it in a container with some sticks and some oak leaves and later that day it built it’s cocoon. It was amazing how intricate the cocoon was done! He made it between two oak leaves (with a stick in the middle)…the leaves were completely flat against each other, with the caterpillar and it’s cocoon inside. It’s been this way for about a month now, and the outer leaf of it’s enclosure as since detached. I read some more on this species and learned that in the pupae state, it overwinters. So, my question is: How long will my caterpillar be in this state, and will it emerge as a healthy moth once it is done?
P.S. I named him Snowball!

Hi Concerned Caterpillar Mom,
Despite the blurriness of your photo, the Laugher, Charadra deridens, has such a distinctive “face” that we believe your identification is correct. This photo on BugGuide is a good reference. Chances are good that you will see a healthy moth emerge in the spring. We would advise you to keep the cocoon in a location where the temperature is similar to the outdoors. Keep the cocoon out of direct sunlight and you might want to spray it occasionally with water to ensure it does not dry out. Not all cocoons produce adult moths. Some caterpillars fall prey to parasitic wasps and flies and though the caterpillar has entered the pupal stage, adult parasitic wasps or flies will emerge after feeding upon the nutrient rich pupa.
Letter 4 – Legume Caterpillar
Subject: Unknown Caterpillar
Location: Daphne, Alabama
August 15, 2016 5:16 pm
Hello, I’ve tried in vain to ID this possible looper or inchworm, and hope you can help!
I found several of them feeding on Rattlebox plants on the eastern shore of Mobile Bay, Alabama last week. Thanks for any info you can provide!
Signature: Joe Thomassen
This was a tricky one. Loopers or Inchworms are distinguished from most caterpillars that have five pairs of prolegs in that they only have only two pairs of prolegs, causing them to “loop” as they move. Your caterpillar actually has two pairs of prolegs, but it also has appendages appearing to be a horn at the tip of the abdomen. Some Owlet Moth relatives in the superfamily Noctuoidea have a similar fake horn, so we searched that superfamily, and it is a big superfamily. We eventually discovered the Legume Caterpillar or Pale-Edged Selenis, Selenisa sueroides, thanks to BugGuide where it is described as: “Larva: body cream or yellow with dull reddish or yellow lateral markings and several thin black dorsal stripes; two reddish or yellowish prolegs; two long anal appendages project backward from last abdominal segment; head reddish with numerous black spots.”
Letter 5 – Probably a Cutworm
Subject: Please help to identify this caterpillar
Location: Apache Junction , Arizona
February 4, 2014 1:02 pm
Found This Caterpillar by some river rocks in the dirt in my backyard. not sure what it is or what it turns into. Please help.
We cannot say for certain, but this is most likely a Cutworm in the subfamily Noctuinae, which is a very large group of moths. See BugGuide for additional information.
Letter 6 – Staghorn Cholla Moth Caterpillar
Subject: What caterpillar is this?
Geographic location of the bug: Tucson, AZ
Time: 12:45 PM EDT
Your letter to the bugman: Can you please tell me what kind of Caterpillar this is? It is on top of my buckhorn cholla plant.
How you want your letter signed: Maureen C.
Thanks so much for letting us know you found this Caterpillar on a buckhorn cholla. Often knowing the food plant upon which an insect is found is of tremendous help in making an identification, and it only took us about a minute to find this BugGuide image of a Staghorn Cholla Moth Caterpillar, Euscirrhopterus cosyra. According to BugGuide: “Larvae feed externally on cactus, rather than boring inside like many other cactus-feeders.”
Letter 7 – The Asteroid
September 30, 2009
I found this in my field in north central Ohio this afternoon on a weed (goldenrod I think). It was a chilly day and it wasn’t moving at all. I’ve looked through my insect guides and on the web to try to identify it, but no luck. Do you know what it is?
Mt. Gilead Ohio
WE just love it when caterpillars have poetically descriptive common names, like the Monkey Slug, the Hickory Horned Devil, or the Orange Dog. Your caterpillar is a first for us. We thought it resembled the Brown Hooded Owlet Moth Caterpillar, so we searched the genus Cucullia on BugGuide. We quickly located The Asteroid, Cucullia asteroides, more commonly called the Goldenrod Hooded Owlet. The caterpillars are highly variable, and there are no images posted to BugGuide that exactly match your specimen, but the coloration is represented in several images from New Hampshire. The caterpillars are described on BugGuide as: “Caterpillar: ‘Usually bright green or brown with yellow, black and white striping, but exceedingly variable…mid-dorsal stripe yellow, often narrowly edged with white, occasionally flanked by variously developed black subdorsal stripe. If subdorsal is absent, then five or six black pinstripes above level of spiracles.’ – Wagner p. 388(1) Base color may also be tan, or purple and brown, especially in later instars.” Your lovely red specimen lacks the dorsal stripe, and has that awesome yellow racing stripe up the side. BugGuide also indicates: “There has been significant discussion whether all these are the same species of Cucullia or not. Seems as though there may be several species that look very similar as larvae. See Also Cucullia postera, C.omissa, C. florea are likely to have similar caterpillars, according to Wagner.”
Thank you so much for taking the time to identify my caterpillar. When I took the picture I thought it was so distinctive that it would be easy to identify. Ha! I’ve spent a lot of time on your site in the past few days and it’s awesome! Thanks again!
