About 4 - 5 weeks ago we started to see bees in our kitchen and we thought it was because we kept one of the sliding glass doors open to the back deck as the weather has been nice and it was convenient for the brothers to go in and out of the house. Wrong. I was out looking at the gutters because it's time to clean them and noticed what I thought were bees going in and out of a tiny entrance in the upper corner near the soffits. So, I figured I would kill them with Spectracide Wasp and Hornet Killer. My wife picks up 4 of them from the local hardware store and I was sure I was safe as it sends a stream about 20 feet so. Safe I was not and got stung by one of those guys... left a welt about 4 inches by 6 inches on my upper right side. Stung me right through my shirt too. So I searched for something that might actually work as we still had the occasional Yellow Jacket coming into the kitchen (I still can't find how they were coming in but it was not because the sliding glass door was open) and those guys were still building a nest inside the walls of our home as I could see them coming and going. I found this stuff called Tempo Dust and read a ton of positive reviews. I figured it had to be the real deal because even the most diligent blackhatter is not going to post thousands of positive real looking reviews. This is a real solid product but you had to administer it in the dark and you had to use this puppy to puff then dust into the crack so it would get into their nest area. You don't need much as I used about 3 or 4 ounces max in the process. I set my ladder up against the house in the early evening when they were inside and calm and then ran like a little girl to safety in case they felt the vibration and came out to see who was disturbing them. The following morning about 5 or so, I put on coveralls, a golf cap, safety glasses, gloves and wrapped my head in a beach towel and started the execution process. I did about 10 - 12 puffs with that device and jumped off the ladder (stupid move as I was up about 6 feet or so and am no spring chicken anymore) and ran into the house. Next day I saw this on the ground: The stuff worked fairly quickly right off and 2 days later I did the 5 AM thing again just in case. Yellow Jacket movement has been almost nonexistent with the exception of a few random ones in the back yard and those are smaller than the average size and I expect that they will be gone in a week or so. So, there you have your weekend instructional on how to eradicate yellow jackets.
