- Tent Caterpillars
- Gypsy Moth Caterpillars
- Tomato Hornworm

B.t. to the Rescue Bacillus thuringiensis var. kurstaki is a naturally occurring bacterium that kills certain leaf-eating worms and caterpillars. Simply spray Caterpillar Killer onto trees, shrubs and vegetables so that worms and caterpillars eat the treated vegetation.
The bacterium includes a toxin that stops them from feeding or causing more damage to your plants. Within a few days, effected caterpillars and worms will die of malnutrition. Safer® Brand Caterpillar Killer can be used until the day of harvest, so you can protect your plants through their entire growth cycle.Won’t Harm Beneficial Insects When Used as Directed Safer® Brand Caterpillar Killer controls and eliminates a variety of destructive caterpillars and worms. When used as directed, this treatment won’t harm birds, earthworms and beneficial insects, such as honeybees and ladybugs. These beneficial organisms are important to our ecosystem, and their survival is vital to the continued production of nutrient rich soil and the natural pollination process of flowers, fruits and vegetables.
How To Use Caterpillar Killer Mix caterpillar killer as directed to achieve desired amount of solution. Once Caterpillar Killer is sprayed onto plants and the treated vegetation is ingested by caterpillars and worms, feeding and damage will stop immediately. Keep in mind that more caterpillar eggs may hatch, so it’s best to monitor the area for newly hatched pests even after treatment. If more caterpillars are noticed, you may need to repeat the treatment again after 5-7 days. It’s recommended to apply Caterpillar Killer late in the afternoon or on cloudy days as B.t. can breakdown in excessive sunlight..An Economical, Easy-to-Mix Solution This 16 oz bottle contains a concentrated solution that creates over 250 times that amount in usable caterpillar-killing solution.

Control Options for Caterpillars in Your Garden
B.t. and pyrethrins are chemicals that can be used to help control the tomato hornworm, cabbage loopers and cabbageworms. B.t. (Bacillus thuringiensis) is an effective method of eliminating your garden or field of the tomato hornworm without environmental concerns or harm to birds and beneficial insects.
Insecticides containing pyrethrins can also be an effective method of controlling these caterpillars.
B.t. kills hornworm larvae, cabbage loopers and cabbageworms thereby preventing further damage. When the worm ingests the B.t., it works as a gut rot poison that makes the worm stop feeding. The tomato hornworm cabbage looper or cabbageworm will stop feeding immediately and die within days of malnutrition.
B.t. usually comes in a dust or concentrate and kills a variety of caterpillars and worms. It will not harm beneficial insects, birds, or earthworms when used as directed.
Sprays with pyrethrins paralyze the insects and result in their death.
Safer® Brand offers a variety of control products for tomato hornworms, cabbage loopers and cabbageworms to help control and eliminate these garden pests and revive your plants. Please check out our tomato hornworm, cabbage looper and cabbageworm control products for more details about how they work and how, when, and where they should be applied.
It is recommended with any pesticide to test plants for sensitivity to the product. Spray a small section of the plant in an inconspicuous area and wait 24 hours before full coverage.
B.t. is generally applied when it is a cooler time of day, preferably later in the afternoon or early in the evening since the product breaks down in sunlight and heat. Carefully read and follow all directions on the product's label.
When applying pyrethrins to infected plants, carefully read and follow all directions on the product labeling for safe and effective application. Do not spray plants in the peak of day or when temperatures exceed 90°F
The parasitic wasp and green lacewings are two beneficial insects that help to control tomato hornworm problems. They can be attracted naturally to your cornfield or garden area where your corn is planted, and there are some companies that grow these insects and sell them to consumers.
Predators of the cabbage looper include lady beetles, spiders, pirate bugs, wasps, birds and small mammals.
A natural control method would be to entice parasitic wasps to your garden so these beneficial pests can help control the cabbageworm.
The parasitic wasp lays its eggs inside the tomato hornworm's egg. These have shown success rates of over 50% and higher. Upon hatching, the green lacewing larvae will eat the larvae of the tomato hornworm.
The predators and parasites of cabbage loopers attack both larvae and eggs, killing them for food as well as paralyzing them and depositing eggs in the larva or egg. When the parasitic egg has hatched, it will feed on the cabbage looper larva or egg.
The parasitic wasp lays its eggs inside the cabbageworm's egg. You can attract parasitic wasps by planting nectar and pollen producing plants in the garden or near crops.
If trying to attract these natural predators doesn't work, they can also be purchased from companies who raise them.
Plant the pollen or nectar producing flora as soon as possible according to the temperature of your area. Most local greenhouses and garden centers can help you determine the right planting time.
Contact a company that raises beneficial insects to find out when they should be purchased and released for maximum hornworm control.
Removing crop remnants, tilling the soil, and handpicking larvae are all methods that will help control these caterpillars. Using covers on rows of plantings of the cabbage family will not only help to keep out the cabbageworm but will also keep out the cabbage looper and other pests.
Handpick then destroy the caterpillars when you have found them. Remember not to disturb any caterpillars having white cocoons on their bodies. These are the pupae of the parasitic wasp. Place covers on rows of plantings according to the accompanying instructions or seek direction from your local home and garden center.
As soon as you find any of these caterpillars, just pick them off the foliage and destroy them, again taking care not to remove those with white cocoons on their backs. Use covers on rows of plantings of the cabbage family before the pest appear.
