I have a ground wasp nest in my lawn that I can't seem to get rid of.
I discovered the nest when I ran it over with my lawnmower about 3 weeks ago and they attacked me. When I ran over the nest it was a bit of a raised bit of underdeveloped lawn and I destroyed the entrance to the nest and could not find one. I treated the entire area of underdeveloped lawn with Temprid SC and that seemed to take care of the problem...until tonight. Mowing again and stayed away from the area but they moved into the lawn and when I went over them they attacked again. It is in the lawn so not sure if I will be able to find the entrance or not. What is the best way to treat these and kill them. Is there something that I should just treat the whole lawn with? Or do I need to find the entrance. Oh and the spot where they are now is about 4 feet from my well head. Thanks
The term "ground wasp" is a broad term used to describe a variety of wasp that nest in the ground. Without a positive identification it is difficult to say which specie you have and recommend a treatment plan. However, the most prevalent ground wasp is the yellow jacket. If you do indeed have yellow jackets then we do have the Alpine Yellow Jacket Baiting Kit with Onslaught Insecticide that may be used in situations like yours where it is difficult or nearly impossible to locate the ground nest. Each kit contains four reusable bait stations with hanging strings and one pint of Onslaught insecticide concentrate, the only insecticide labeled for Yellow Jacket baiting. You use the stations by placing a mixture of tuna, chicken, or other food attractant with a small amount of Onslaught Insecticide in each Alpine bait station. The stations are then hung around the outside of the home, out of reach of children, but accessible to yellow jackets. The Alpine bait stations will attract the stinging insects where they will contact, ingest and spread the insecticide, eliminating the yellow jacket problem sometimes within just a few days.
