This may seem like a silly question, but…
The scenario is that I'm adding a bit of storage underneath the bottom half of our stairs. Up until now it was just a closed in space that was being wasted.
So I pulled off the sheetrock and found a deserted mouse metropolis. LOADS of fiberglass insulation chunks mixed with a huge amount of seeds, mouse poison and mouse poop.
Eww.
Shop-vacced it all out, bleached every surface, sprayed it down with animal-pee descenter and went to work figuring it out.
Turns out the contractors were incredibly lazy in their hole cutting in the subfloor. There was huge gaps around the vent pipe and the electrical wiring that went down into the crawl space.
I went and got some rodent-proof great stuff and spray foamed all the openings and now it's all clean.
The question:
Before I close it all back (I'm adding some built in drawers in the front), should I toss in some mouse poison pellets? Is that a smart 'plan b' in case they get back up in there somehow, or is that only going to encourage them to get back up there because the poison attracts them?
Best Answer
No you shouldn't.
If you put animal bait there, a stray rodent might find its way in there and perhaps die, which would cause a stinky problem after a few days. If you did a sufficient job sealing up the area with spray foam, the problem shouldn't come back!
