You should have gotten them last fall when it turned cool (providing it turns cool enough where you are)....they hibernate. If they havent come out yet, you still might be ok. You need to get some spray and spray it into where they are coming out.... Heres another wasp story for you.....Our last house was what some might refer to as a fixerupper...the upstairs was barely habitable so that of course was our masterbedroom while the kids got the less scary area..... Anyways, I was lying in bed one morning and could hear this buzzing noise in the room, I figured it was a couple houseflies, we had bought the house in the winter, this was our first spring in it. The buzzing got louder so I opened my eyes. I wear glasses and could see a few little "flies" flying around the room but they werent flying like flies, curiouser and curiouser.....so I reached for my glasses, put them on and......the room was literally swarming with yellow jackets!!!! I layed there in disbelief and watched them drop one by one out of a tiny hole in the ceiling above my head....there had to be a few hundred in the room. I slid out of our bed, crept to the stairs and went down, shivering and shaking all the while! LOL I HATE BUGS!!! So I call Mike, have him go to the exterminators to get something for them ....well, he's a confident, strong person but the one thing in the world he is afraid of is bees and wasps. He goes upstairs to spray wearing his jeans, 2 shirts, a pair of coveralls which he has taped shut at the ankles and wrists, a pair of heavy workboots, gloves and his MOTORCYCLE HELMET!!! He looked like an alien! LOL He went up and sprayed the room then squirted some powder stuff into the hole and stuffed the hole up.....and we moved that fall.... Brenda
