The Non Chemical Method:

Here is a little trick that I heard on some environmentalists program & tried out this summer....

Take a brown paper bag ( or several if you have a big problem), the thicker the paper, the better as it needs to be able to hold up to rains for a while.
Blow it up ( like a balloon),
and hang it around where you see wasps & bees nests.

The insects then believe that there are other nests around & they tend to move on.


I tried this about 6 weeks ago. as I noticed that there was two areas in the soffit of the house ( in under the roof rain drains) that wasps were crawling in & out of. There were constantly wasps on my deck and I have three toddlers that I was afraid might get stung...
( I did get stung twice getting out of the hot tub)
I couldn't buy a wasp trap because there wasn't really anywhere to put it that the kids wouldn't get into it & I hate to use poisons for the same reason ( although I would have if necessary).

I hung up my big paper bag between the two areas, and about 10 days later, no more wasps!
I can't believe that actually worked, but it did

The bag has since been totally destroyed from rain, but the wasps have not returned

Good Luck!
