Summit Mosquito and Gnat Barrier Covers 10,000 Square Feet, 1/2 gallon

Excellent product to reduce gnat population! I live near Washington DC and our neighborhood has a huge gnat problem. We can’t walk through our yards without getting dozens of them swarming our heads. Using BTI dunks in traps, fountains, and gutters didn’t make a difference (although you still 100%). I suspect they are growing eggs in the mulched areas. Either way as adults they exist by the dozens in our regular grass lawn area. Off! yard spray and spectracide yard spray does NOT work, despite the chemicals listing online as gnat killers. It may be the concentration. Anyways this summit product works well with permethrin.After spraying it’s a clear difference. From dozens to 3-4 only flying around as we walk through. It’s a clear and significant knockdown of the gnat population. How long it lasts really depends on the rain and how fast the survivors breed (this is why still use BTI in any breeding water areas). Rain I can’t control, and neighboring yards I also cannot control. Regular rain I’d say it lasts about 3-4 weeks. Heavy flooding rain probably 2-3 weeks. I aim to apply every 2-3. HOWEVER if there’s a really bad infestation after a long period of heavy rain, you might need to spray 2x over a few days to really get the annoying buggers

listen to the reviews 😂 I sprayed this and I live in a heavily wooded neighborhood. After spraying this it feels like the air is sitting still outside now

I bought this product trying to get my hopes that it would work. I did read a good amount of reviews and said the worst is that it won’t work but to my surprise it actually does. I sprayed my yard yesterday morning and also my deck and I want to say within the hour you could tell the difference. Still had a mosquito here and there but not like before. It was so bad that you couldn’t even stand outside for 2 minutes with getting eaten alive and there would be swarms of them. So the fact I may see one or two is just nuts because my yard was infested. So this will be something I plan to keep in my home to treat my yard regularly.

Not very happy with the product. Still got at up by sandfleas, but haven't seen the mosquitos.

This is all you will ever need!!! I live by a creek surrounded by trees and the gnats are beyond awful! I thought I have tried everything and it was always a fail. But this product right here…. It’s beyond amazing!! lol works instantly and lasts a long time.! I do recommend doing it again after each time it rains.

It burned my entire bush. Yes, did great with mosquitoes but they will need to change the packaging as it states it’s safe for plants, etc… I know my bush needed pruning, but I loved how large it had bloomed, and I had to cut all of it off because it burnt the bush leaves.

It works immediately and long lasting

Works for about 10 minutes. After that, the flies and gnats come right back.
