Is it safe to place Dekko Silverfish Packs in air vents?
We would not suggest placing Dekko Silverfish Packs inside air vents. It is not permissible on the product label to place the packs in vents, but normally that would not be a hiding place for silverfish anyways. Normal harborage areas for silverfish are closets, drawers, bookcases, basements, garages and other dark hidden places.
