How can I get rid of Bee's in roof eves without using harmful pesticides? Or is there some form of deterant to use to keep them away?
Well, considering where they are located, they probably aren't bees...most likely they are yellow jackets or wasps...the only way I can think of to get rid of them without a pesticide, is to get those yellow jacket/wasp traps out early enough in the spring, to catch the queens. Otherwise, you have to live with them until next spring. Until you KNOW there are no workers in the nest, do no plug up holes or the areas where they crawl in and out. They are more than capable or "chewing" the other direction, and coming into your house.
I had a bees nest and I took a water hose and knocked down the nest but you can call an exterminator to be safe,,,
Once you get them out, I reccomend checking for anywhere that they might get in.
