I just moved into a house that has been vacant for two years. The first week I was here there was a wasps nest over the garage, I used the spray & they went away. About two weeks later the built another nest just on the other side of the house in between the window & the storm window, there was a small tear in the screen. It took a couple of days but I got in there & sprayed them too. Three days later they were back at the same nest...I guess I didn't spray it as well as I though. I got up at about 3am opened the top of the window & let them have it. The next week they were building another nest in the same window on the opposite side. I got them before they got too far. Now I have them flying around the back patio trying to get into the sun room and I think they have build a nest on the next corner over in the roof drain. I am deathly afraid of them & I don't know if I can climb a latter to get up there. I think I would be too vulnerable. At this point I'm feeling they are out to get me HEHE. If anyone has a suggestion on how to get rid of them for good that would be great. They have the whole woods behind the house they are welcome to build a nest there, just not on/in my house. Thank you for you help
