last year we had wasp bad. and now its just getting warm and they are already coming out! they are the agressive type to. i walked around the corner of the house last year going to the chicken shed and i had the same wasp come at me three different times going that way until he finally got me!! we spray them and kill them with a fly swatter but they just keep muitiplying! would a bug zapper work for them? im some what allergic to them. not so bad i have to go to the hospital but i swell up! plus i worry about the kids. they are 3 and 5!!
