## Description

Biological caterpillar and webworm control, that, when mixed with water, yields 12 to 24 gallons of material. Our convenient hose-end quart makes spraying shade and fruit trees a breeze.

Review: This product was easy to use and covered more than I expected. The coverage was great but gradually turn your hose on because the speed was powerful! Seemed to work well and definitely cut back on the number of bugs, we live in a very wooded area.
Review: Big invasion this year of bag worms. Tried neem oil, not so great, worms remained and trees were still being eaten. Based on other reviews thought Id try this stuff. Am sure glad I did. Instructions said: spray weekly or after a rain. OK, after first spraying caterpillars mostly disappeared from my Mountain Laurels and my front porch. After second spraying no more bag worms or caterpillars. WOW. Note: I bought the version with the attached sprayer as it has the range to reach the top of my trees. Works well, I recommend it.

## Questions & Answers

**Q: Can this be sprayed directly on to vinyl siding house that is covered in caterpillars?**
A: Yes, but it works best sprayed on what they eat. If it rains on the siding, it will all be washed away. It should not damage the siding, it is just a biological spray.

**Q: Will it work on BAGWORMS?**
A: Absolutely, it did great in bag worms.

**Q: can you spray this on bushes?**
A: yes. I used it on junipers that had a very bad case of bagworms. It didn't hurt the bushes at all and did kill the worms.

**Q: will this harm any plants & flowers?**
A: I use it yearly on my evergreen trees that surround the back yard.  I follow the instructions and have no issues.  Tall grasses and burning bushes are next to the evergreen trees and receive the spray.  There has been no affect on either of those plants from the spray.  I cannot answer for other plants, but believe used as instructed, most plants will not be affected.
