Q&As

1 - 2 of 2 Questions

Q: Will this take care of the armyworm moths, larva and armyworms

8 months ago
1 Answer
  • A: Yes, this kills armyworms, especially when they are small, by disrupting their digestive system after they eat it. Once ingested, it causes the larvae to stop feeding and die within a few days. For best results, apply it when caterpillars are young (less than 2 cm) and ensure good coverage on both sides of the leaves. It will not affect the adult moths.

Q: How high will spray reach from ground?

9 months ago
1 Answer
  • A: Generally speaking, 15 to 20 feet but much depends on the diameter of your hose and your water pressure. A thinner longer hose will reduce the height and conversely a shorter, wider diameter hose will increase the height.

Works well and convenient to apply.

6 days ago
This seems to have arrested the web worms pretty well. The ability to use a hose to apply it is very convenient. Need to keep applying regularly as the invasive pests are very persistent.

Yes, I recommend this product.

Waste of money

The hose end sprayer didn't work. It sprayed but did not dispense product so I returned it for a refund.
