Safer Caterpillar Killer Concentrate 16oz

Safer Caterpillar Killer with B.t. is a concentrate that controls tent caterpillars, gypsy moths, cankerworms, spruce budworm and other caterpillars on shade trees, ornamentals and evergreens. One bottle treats two to three large shade trees.

What caterpillars does it control?

• Tent caterpillars
• Gypsy moths
• Spring and fall cankerworm
• Spruce budworm
• Jack pine budworm
• Other insects that infest shade trees, ornamentals and evergreens

How does it work?

It uses Dipel^® (Bacillus thuringiensis var. kurstaki). Once a caterpillar or worm eats it, it dies within a few days. It is safe, easy to use and effective. BTK does not harm people, animals, birds or fish. BTK is found naturally in soil and breaks down within a week in sunlight.

How much does one bottle make?

It is a concentrated formula in a 16 fl. oz. (500 mL) bottle. Mixed with water, it makes about 16 gallons or more of spray solution, enough to treat two to three large shade trees.

How do I apply it?

Mix with water and spray into the foliage of the infested tree. Apply late in the afternoon or on cloudy days, since B.t. breaks down in sunlight. Repeat every 7 to 10 days if needed.

Why do caterpillars matter?

Caterpillars, or worms, are the larvae of beetles, butterflies, moths and flies. They go through complete metamorphosis, changing from a worm or caterpillar into a winged adult with legs. They do the most damage to trees and shrubs in the larval, or caterpillar, stage. Some species, especially the gypsy moth caterpillar, can seriously damage trees, and large infestations can completely defoliate large mature trees.
