What can I do to get rid of swarms of gnats flying around in my yard, bothering us when we sit out there. I keep my grass mowed pretty well, so I don't know why they are hanging around out there. What can I do?
There is a granulated BT product that can be spread with a lawn spreader. I do not recall the name of the product and it was only available at my pest control chemical supplier. I used it to get rid of a gnat problem on an apartment complex property. The BT I refer to is bacillus thuringensius (sp). Another formulation of that is called dunks for eliminating mosquitos from ponds.
You might find a local pest control company to purchase it from, since most chemical suppliers are not retail.
