Foam sticks and keeps killing!
The absolute best spray. The way it foams up, it keeps getting the wasps which coming out. Particularly good when the nest includes under eaves or other crevices.

Fast, Effective, and Reliable Pest Control
Every year the yellowjackets seem to get worse, but this product has been a lifesaver. The Black Flag Foaming Wasp and Hornet spray works great—takes out nests quickly and keeps the pests at bay. I really like the long squirt distance, which lets me treat nests safely from a good range. Being able to buy it in multipacks is another big plus, so I’m always stocked up when needed. Highly effective and well worth it.

Black Flag Foaming Wasp and Hornet spray is a powerful and effective solution for dealing with pesky flying insects. I recently used it to tackle a wasp nest near my home, and it worked like a charm. The foaming formula sticks to the nest, ensuring complete coverage and reaching areas that might be difficult to access otherwise. One of the best things about this product is the distance it can reach, allowing me to keep a safe distance while spraying. The foaming action immobilizes the wasps and hornets on contact, making it easier to take care of the nest without worrying about getting stung. I appreciate that this spray works quickly, providing rapid results in getting rid of the pests. Additionally, the residual effect ensures that any returning wasps or hornets are taken care of too. As with any insecticide, it's essential to follow the instructions carefully and exercise caution. Overall, Black Flag Foaming Wasp and Hornet spray is a reliable and potent option for dealing with these annoying insects around your property. It gets the job done efficiently, making it a must-have for anyone dealing with wasp or hornet issues.

This spray knocked down pissed off flying yellow jackets instantly so it has my vote.
Had to use on a in ground yellow jacket nest during the day which is not the right time to spray but I had no choice. When I came back the next week to cut the lawn the nest was dead as nothing came out even after hitting the old Oak stump they were using.

Black flag,
It was okay. Didn't seem to have much in them. I have other brands that I like but they were out. So it had to do. It will kill.
