Personally, I have no idea if those work or not.

If it were me, I would buy, at least six, five-gallon pails and replace the lids with these:

Bait the lid traps with peanut butter, put two gallons of plumbing antifreeze in each pail, and put one at each corner of the car as well as beside the middle of the doors. Check daily for what the traps have caught.

Hope this helps.
