So, I have had a yellow jacket problem for a little over a month.
I would kill anywhere between 10-20 a day inside my house on a bad day, 2-3 on a good day, and I would find carcasses by the windows and in the basement. They would come out of the A/C vents a lot on all floors.
I sprayed some cheap walmart spray and hoped it would help, but it didn't really. I finally had a pest control guy come out and he spotted them going under the siding in 2 different spots. He gave a free quote and left.
The strange thing is that this was last Thursday, and I haven't seen a single yellow jacket (dead or alive) inside the house since then. That Friday, the temperature dropped significantly. It has gone back up since then a bit but I haven't seen any more inside the house, only out in the yard.
He quoted $145 to climb up a ladder and treat the problem areas and it came with a 6 month warranty. I am on the fence at this point about whether or not I should go ahead and have it treated or just wait a little bit longer and see if the cool weather solved the issue. Even if it does, will they just come back to the nests in the spring?
I probably won't do a DIY due to not wanting to be stung. I have had some close calls, but they usually just land on me and don't sting.
Any advice/experience appreciated!
