We have relocated to a country home and are covered up with Red Wasps & Hornets. I have been disappointed for years with the Jet Sprays for bees that they have in the stores. I remember when these first came out 30 years or so back. The first generation sprays were awesome. You would hit the bees and they would drop to the ground and be dead quickly. Somewhere along the line the formulas got changed and the current stuff is wimpy AF. So I hit the googler for Reviews and found this one. The Spectracide in the stores sucks - but they have a PRO version that's not sold in stores that I have seen but it is available on Amazon. I was going to try a single can but that seller was out of stock. The reviews on the PRO formula were excellent so I ordered a case of 12. Came in today and this stuff must be of the original formula variety. Hit some wasps and they dropped straight to the ground and quickly died. So if you're needing this, give this a try. I did not do any searches to see where else you can get it but it is on Amazon.
