Other types of exclusion devices

Beware of other exclusion methods that retailers will advertise as "universal." And be advised that such repellants, traps, and netting are not a one-sized-fits-all miracle cure to your nuisance wildlife control problem. Most traps, funnels, and netting is best suited for one type of animal.

For instance, you wouldn't use raccoon traps to capture bats in your attic. You'd use one of the exclusion methods outlined above to prevent bats from reetering the roost once they go out to feed, forcing them to find a new home outside of yours. Most wildlife removal companies will use large traps for Raccoon Removal that lock them inside once they enter, so they can be safely and humanely returned to the wild away from your home.
