Wasp Traps

I think they are just too stupid to think to do ths.

I looked up wasp traps on google and found many sites that shows how to make a trap. One site had pictures. They used a clear plastic bottle and cut the top off. Then inverted the cut off top and stapled to the bottle. Pour some product into the bottle to attracts wasps and hang from a tree.

The wasp enter the trap from the top, not the bottom. They can't figure out how to escape. Also suggested to add oil to the insides of the bottle. If the wasp try to alight on the inside of the bottle they will fall to the bottom.
