Caterpillar Killer with B.t. is a safe, easy-to-use and effective control for caterpillars including tent caterpillars, gypsy moths, spring and fall cankerworm, Spruce budworm, Jack Pine Budworm and other insects which infect shade trees, ornamentals and evergreens. It utilizes Dipel® (Bacillus thuringiensis var. Kurstaki) which, once ingested by the wayward caterpillar or worm, kills them within a few days.

It is a concentrated formula in a 16 fl. oz. (500mL) bottle that when mixed with water makes about 16 gallons or more of spray solution. One bottle of the BTK concentrate will treat two to three large shade trees. Treatments should be repeated every 7 to 10 days, if required.

Simply mix with water and spray into the foliage of an infected tree.It is recommended that this product be applied late in the afternoon or on cloudy days since B.t. breaks down in the sunlight.

BTK is found naturally in soil and degrades within a week as the sun hits it. BTK does not harm people, animals, birds or fish.

Caterpillars, or worms, are the larvae of beetles, butterflies, moths and flies. During their lifecycle they undergo a complete change or metamorphosis. During this process they change from a worm or caterpillar to an adult that has wings and legs. They cause the most damage on trees and shrubs during their larvae or caterpillar stage. Some species of caterpillars, especially the gypsy moth caterpillar can cause serious damage to trees. Large infestations can completely defoliate large mature trees.

Note: Not available in this format in Canada.
