Safer® Brand Caterpillar Killer with B.t.
Safer® Brand Caterpillar Killer with B.t. (bacillus thuringiensis var. Kurstaki) is an effective organic solution for caterpillar and worm control. Caterpillar Killer kills worms and caterpillar stage insects, but has no effect on birds, earthworms, or beneficial insects, such as honeybees and ladybugs, when used as directed. Worms and caterpillars eat treated foliage then immediately stop feeding and damaging plants.
Effective for: Cabbage looper, imported cabbage worm, tomato hornworm, bagworm, spring cankerworm, fall cankerworm, gypsy moth, tent caterpillar, elm spanworm, fall webworm.
How it Works
When the B.t. is ingested by the worm, it works as a gut rot poison that makes the worm stop feeding. The caterpillar or worm will stop feeding immediately and die within days of malnutrition. This caterpillar killer will keep your lawn and organic garden, free from caterpillars all year long.
It is recommended that this product be applied late in the afternoon or on cloudy days since B.t. breaks down in the sunlight.
Carefully read and follow all directions on the product's label. B.t. is very specific and only works on caterpillars and leaf feeding worms. 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.
Apply Safer® Brand Caterpillar Killer when pests are first noticed and repeat every 5-7 days or as necessary. Caterpillar egg hatching can occur over an extended period of time. Monitor treated areas for the presence of newly hatched pests and retreat if necessary. Thorough leaf coverage is necessary for effective control. After ingesting a treated portion of the leaf, caterpillars stop feeding in a few hours and death occurs in a few days.

Review RateEasy processI ordered the caterpillar killer a few weeks ago. The process could not have been easier and it arrived quickly. I'm very pleased.
Review RateEvergreen happinessWe have several lovely evergreens, in fact so many that a child thought maybe Santa lived here. Well, those lovely white moths fluttering like decorations on the bushes left nasty caterpillars. They wiggle no more! One application and Santa's trees are safe again...even in HOT Texas!
Review Rateeasy applicationI love BT. gets ride of the cabbage worms and flea beetles (that get on eggplant leaves)
Review RateFANTASTIC PRODUCTSExcellent RESULTS Everytime.
Review RateIt works!Cankerworms have been a serious problem in the Charlotte, NC region for the past 30 years, and a plague for the past 7-8 springs. Even banding 47 trees barely puts a dent in the problem. We received the "Caterpillar Killer" about 3 days after the 2016 munching began. The leaves we were able to reach (with a 12 ft. ladder and a high spray arc) have some 'nibbles', but they're doing great. The leaves we could not reach are mostly leaf ribs. We're spraying every 5 days. BTW, a 12 oz bottle of the concentrate goes a long way.

Review RateAmazon Reviewput Bt in your watering can to kill gnats thriving in the soil. It does not damage houseplants or garden plants. I've been using it for gnat control for over a decade. Safer is my favorite brand, but I wish it came in larger bottles.

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.
