Any pest control experts out there? Ever since I moved into this house three years ago, I've had trouble with yellow jackets. Up until this year, the nests have been away from the house. Now, unfortunately, they're under the siding and I'm not having much luck getting rid of them. In the attached picture, the nest is somewhere to the left of the front door in that area behind the light. I first noticed them coming and going where the white trim meets the j-channel on the sheltered part of the door opening. I blew a bunch of permethrin dust into that open, and all was quiet for a few days. Then, I noticed them coming and going from under the soffit above the door. Same thing, I dusted them and there was nothing. Now, they're entering and exiting where the siding meets the corner post, above and to the left of the light. I'm starting to get a bit nervous here. This is hard to describe, but that area to the left of the door is hollow. I can't readily access it, but I think it's probably a 2x2 open space, the height of the first floor. My house was cheaply built (don't blame me!) and there is no exterior OSB sheathing. Just a bit of blueboard insulation. I'm worried the jackets have chewed through the insulation and have a nest inside that hollow spot. I'm almost ready to call an extirminator, but was trying to save $200. Just want to get them killed before they find a hole into the house.
