Heres a few home remedies to get rid of those annoying beetles:
Get a one gal. milk jug and cut it open not too big. Leave the handle on it. Now mix 1 cup of warm water with 1/4 cup of sugar and yeast. Mash a banana in there too.
Get a 1 1/2 gal. chapin sprayer. Fill with warm water about 3 tsp of garlic powder. 2 tsp of cayenne pepper. A couple squirts of dish soap and a little under 1/4 cup of veg. oil shake and spray the little buggers really good. They dnt like the smell but it works.
