BengalFoaming Wasp and Hornet Killer – Long Range Wasp & Hornet Spray with Foam Trapping Action – Non-Staining Outdoor Long Distance Foaming Wasp Spray – Kills on Contact, 18oz, 1-Pack

Had a problem with a small opening in our rock garden into which some wasps had started to build some sort of nest. A few zaps of this and all the wasps have died off. A week later, the foam is still there blocking the entrance and whatever wasps were inside cannot get through the hole and have died off.

For 4 years I have been battling with wasps making nests in the soffits of my house. I have used every kind of wasp spray with minimal, or zero, results. A couple of weeks ago several huge nests of wasps appeared on my house. The wasps were so abundant they were hanging in big clusters in several areas. I freaked out. I tried to call a pest control service but had to leave a message. They never returned my call and I needed to do something real fast, and didn't really have the money for that anyway. So I went to Amazon and found this Bengal wasp spray with really good reviews. I liked the fact that people said this stuff comes out like a foam and hangs around for a while. I bought 3 cans of it. I was very pleased that it did indeed blast out and stuck to the wood and clung there. I blasted all of the nests. A few minutes later I went out to check the progress and there were hundreds of wasps on the ground dead, and plenty more squirming around all over the grass breathing their last gasps of air. This stuff is AMAZING!!! Since then there have only been about 5 wasps that returned to the sight, probably in utter confusion, but NO activity at the nests! I will definitely buy more of this to have on hand so that I can keep things under control from now on.

The best product I have found for wasps. The foam is far reaching and quickly traps the wasps. I keep a stash of cans for the summer months when wasps are active. Highly recommended!

doesnt spray as far as stated

Needed 2 cans for large hornet nest.

Around dusk, I shook a can well and went to use it on a small wasp's nest, under my shed roof overhang. It came out with such force, if the foam didn't kill them, the impact might have. However, the next morning, I could not generate any pressure inside the can and it dribbled out the nozzle. If all I get for $18/can, is one use, then I certainly wouldn't buy them again. I did not try to use the other 2 cans I bought via Amazon. I'd been using Spectricide and Raid cans, which you can use for weeks, until a friend recommended Bengal, which I had never heard of before (except the Tiger).

Knocks down hornets on contact. Best stuff ever

Provides a sneak attack on taking down wasps & hornets. Unlike other brands, this one doesn't stir up the nest while spraying. Seems the wasps initially respond to being sprayed is like water & they don't get excited. Doesn't create a stir-up of the nest causing fly-offs. 30-60 Sec later the wasps & hornets cease to move.
