We had yellowjackets invading our house. We couldnt figure out where they were coming from so we called All Green Pest Control. Dave found where they were coming from and plugged up the hole. He then killed the nest from outside the house. We were glad that we didnt tackle this problem ourselves. He had a bee-suit on and the yellowjackets were all over him. Be safe and dont tackle the big yellowjacket nests yourself. I had called several companies and All Green Pest Control took care of it for the lowest price.
