So the exterminator sent someone out who actually has a clue (I was livid but anyway) to do a full assessment of our situation.
A worker is going out to seal some gaps in the crawlspace next week and they are going to install four of something like this, that is anchored to the porch, one by each ingress point. You will see similar traps by the sliding doors at places like WalMart and Lowes if you look for them.
It will cost me an additional $5 per month on our maintenance plan to service the boxes.
