This is a two part question based on a one-part situation.
The wife noticed a chipmunk rummaging through her clean laundry basket in the basement this morning. On my perusal of the laundry area, I noticed a few more clues about their presence (like I needed any more…). The little rodents have eaten completely through the dryer vent tube in multiple places. I’m guessing this is their point of entry, since I also noticed from the outside of the house that there is no grate/screen of any kind covering the dryer vent. The chipmunks have also taken up residence in the wall of the basement, taking advantage of a too-large hole for the washer/sink drain pipe. Spent acorns everywhere.
So, the questions:
Do I need an extra-strength or homebrewed method to screen the dryer vent tube, or can I pick up a regular-ol’ one at the local hardware store (or home depot)? What will these buggers chew through? Note that there’s nothing in the laundry room or basement attracting their presence like food or water, just a nice cave for them.
What sort of poison can I toss through the hole in the wall in case they are living in there or have dug a hole from outside? Will mouse poison do? Rat posion?
