We had our RV parked at a storage place near a tree and we now have carpenter ants living inside the RV. I have killed a TON with traps and bait but everytime ( about 2 weeks now ) that I open the RV and vacuum up the dead ones I see live ones. I was told to set off a "bomb" fogger in there. Is this a good idea? Just worried about all the outlets, instrument panel, etc.
