How to Get Rid of Armyworms in your Garden

Stop Armyworms from destroying your garden

It’s so exciting when you spot your first red tomato of the season. But when you see armyworm caterpillars in your vegetable garden, there is no time to spare. By the time you see signs of armyworms or armyworm damage it can be an uphill battle. An armyworm infestation can devour a tomato plant in record time. They don’t discriminate. These destructive pests can cause significant damage and will eat the leaves and the fruit, red or green. They don’t just attack tomatoes either — they can destroy most of your vegetable garden plants.

Armyworms can remain hidden from site because they hide in the shade on the underside of leaves during the day. Armyworm larvae vary depending on the different species of armyworm. There are three species of armyworms:

Western Yellowstriped Armyworm – These have two large and many smaller yellow stripes. In the larval stage they are black.

Beet Armyworm – These are pale green with light colored stripes that run down the length of the worm.  The eggs are laid and covered with hair-like scales.

Yellowstriped Armyworm – These have two large and many smaller yellow stripes.  The larvae are black.

The good news is once you spot them there are five strategies for armyworm control. You can save your plants from these garden pests, but act fast!

1.) Pull them off the plant and drop them in a bucket of soapy water, or stomp on them.  Be sure they are dead, so they don’t just crawl right back into your garden.  This can be a fun activity for kids in the garden.

2.) Spray your garden with Spinosad. This armyworm treatment is an organic pest spray that can kill a variety of worms and caterpillars and is safe to spray on food that will be eaten later. You can find spinosad based products at Amazon.

3.) Spread Bacillus Thuringiensis Dust (“BT”) – BT is not toxic to humans or animals and it may take a few days to work.  Without giving you all of the gory details basically worms are no longer able to eat and they die. BT products are available on Amazon.

4.) Neem Oil – Neem oil comes from the neem tree, and will work for smaller worms and larvae but it won’t always work on larger adult armyworms. You can read more about neem oil in this article: Neem Oil General Fact Sheet. Neem oil can be irritating to skin and eyes. Make sure you read the product label and be sure to wash any fruit that is sprayed. There are many neem sprays available on Amazon.

5.) Use natural predators in your garden. This can be a harder one to manage, but there are some insects you can add to your garden that are natural enemies of armyworms. There are many birds and beneficial insects that can destroy armyworms. You can use bird feeders to attract birds to your garden. Beneficial insects include ladybugs, lacewings and trichogramma wasps. The trichogramma wasps are parasitic wasps that insert their eggs inside of pest eggs killing the larvae. See more about that in this article: Know Your Friends Trichogramma Wasps. You can purchase wasp eggs for your garden at Amazon.
