i'm trying to prevent rats from getting into an outdoor shed. i've thoroughly checked the whole interior, and the only opening is from the front door (see the right door in the picture. ignore the left door, that only closes fully from the outside).
my intuition is that i should get a foam sealing tape, but i'm concerned that it won't repel pests. in this situation, i don't really care about thermal or humidity leaking, only something that rats won't chew through. any suggestions?
