How to I eliminate and repel fungus gnats on my 1/2 acre property that will always have wet spots?

Our 'yard' is just under 1/2 acre and always has a couple of wet spots. The fungus gnats are so bad, I can't play fetch with my dogs without a net on my face or I have to constantly wave my hands to keep them away. Everything I read requires allowing the wet spots to dry in addition to pesticide. This is not an option for reasons I won't get into. I need to know how to control these things. Thank you for your help!


Unfortunately, insects like fungus gnats breed in wet areas since they feed on the micro-organisms found in that wet soil. Unless the environmental conditions are altered, you cannot expect to eliminate these insects. You can use a natural insecticide such as EcoVia EC which does not have restrictions on use around aquatic areas. This product will have residual when kept dry. We would also recommend using personal insect repellents and perhaps ThermaCELL lanterns as well.
