SummitMosquito 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

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!

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.

We had sod installed in our backyard and along with the sod came gnats. Obviously new sod needs lots of water and the gnats took full advantage of it. We hoped the swarming gnats would eventually die down but didn't. We searched for a solution and came up with a few options. One option was Summit Mosquito & Gnat Barrier and after calling the company and speaking to a live person, decided to give it a go. So far no gnats!!

I bought 2 bottles of this product with the hopes that it would solve the gnat problem in my yard. I sprayed my entire yard 2 times. It worked for 1-1/2 days and then the gnats were back. It was a complete waste of time and money. I'd look somewhere else for another product.

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

We have a lake house, and the nats were the worst. I sprayed this on the porches, and all landscaping out to about 20 feet of the house. Then did the same thing the next day. For nearly 10 days - NO nats. I applied it again about 10 days later and we are nat free. Its worth it for me.

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