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

Great buy! I already use the mosquito bits, so decided to give this a try! Works even better! Able to sit outside late into the afternoon/night with no bite from mosquitos at all. Would highly recommend. It has now become apart of my outdoor must haves!

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

I have used this product before. My spring and summer months are made better with the help of this product. My favorite thing to do is to cut the grass and then spray the yard down. Then in the morning, I can sit on the porch and enjoy my morning reading a book or just drinking my coffee without being bitten by gnats, mosquitos or fanning flies away. Sometimes I spray twice a month for reinforcement even though I don't have to. It last for over 5 weeks. I placed this order for next spring to get prepared ahead of time. Thank you for my order.

This product truly worked. I don't see any flies, nets, or mosquitoes flying around in my yard anymore plus It has stopped them from coming in doors.

Worked pretty well for a few weeks

avoid! not safe. water delivery system is a joke. it stopped working after a minute, and then started to gush out drenching me totally with the chemical.

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

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