    Frequently Asked Questions

    Would it work by spraying general areas where wasps are? I don’t see a nest but there are wasps around my rooftop I need gone.

    It did not work for me. The nest was inside a window dormer. I spayed the area multiple times with little effect. The yellow jackets were not deterred.

    Can you use this as bear mace?

    Only when the bears are hibernating in their paper nests

    Buying to use as a defense weapon. How many 20 feet sprays are in each can?

    Don’t know because it got rid of the nest with one spray, the nest was underground and I covered the hole after spraying and the nest exploded all over my driveway and the hornets never came back

    Would you use this product as hornets or bees are attacking you? Is it harmful to have on your skin?

    It is harmful to get it on your skin. I wore a latex glove when I used it. It kills other insect as well instantaneously. Caveat: It is hazardous to humans and animals; kills hornets, wasps, bees and any other insects.
