This is a bad hornet year. Many are in our cherry tree- we are not harvesting the cherries this year.
Yes, Onslaught Insecticide is labeled to kill hornets that come in contact with the treated area. If you know where the nest is located, you can dust nests, or you can spray the nest with a quick knockdown aerosol like Wasp-X Wasp and Hornet Spray. You would want to follow up with a long-lasting residual product, like Onslaught, to ensure that all members of the colony are eliminated. Onslaught has a 30-day residual outdoors and a 90-day residual indoors.
Onslaught cannot be used on any edible vegetation. We do carry Cyonara Lawn and Garden and Malathion 57%, each of which can be used on different fruits and vegetables. Malathion has the broadest label and is our most popular product for customers who need to treat fruit and vegetable plants. Always read the product label to be sure the plants you need to treat are listed. We also recommend contacting your local cooperative extension office to seek advice on the best products for plants and insects in your region.
