Rodent Exclusion

The Basics of Rodent Exclusion

Rodent exclusion comes down to sealing off rodent entry points around a home or business. It’s crucial to seal every entry point during this process, which means you need a thorough rodent inspection beforehand. This is because rats and mice are smart, and will find and use any entry that may have been missed. Naturally, this also means that the materials used to seal entry points must be impervious to chewing. If rats and mice can get through something with their teeth—which have evolved specifically for continuous gnawing—they will. Some examples of rodent-proof materials are galvanized steel screen, metal flashing, and concrete. Conversely, things like cans of foam aren’t reliable for sealing entry points off, as rodents chew right through soft material.

How Exclusion Fits into Rodent Removal

Rodent exclusion is the second step in our proven 4-step rodent control process. The appointment for an exclusion technician to seal all entry points around your home or business follows the initial inspection. Your exclusion technician will follow the detailed map in the rodent exclusion report your inspector created to seal all identified entry points. While doing so, the exclusion technician will also check the trapping systems set up in the initial inspection. If necessary, the exclusion technician will remove any rodents caught in the traps, and reset them. And once this work is complete, Eastside Exterminators can proceed to helping you with rodent protection. This third step in our process keeps rats and mice out once we’ve removed them.


Why Our Rodent Exclusion Services Are Superior

Effective rodent exclusion for homes and businesses demands extensive knowledge of how rats and mice behave, and what they’re capable of. Moreover, it requires an understanding of typical construction practices in order to make the best use of rodent-proof materials. That’s why Eastside Exterminators rodent exclusion technicians must complete a 12-week course learning the ins and outs of the process.

All this is to say that rodent exclusion doesn’t simply mean going around a structure slapping on a few screens. There’s science behind what we do, and we apply it to our entire wildlife control system.

Reasons You Need to Get Rid of Rodents

Rats and mice can do a lot of damage. Rats can burrow, chew and gnaw wood, sheet rock, insulation, vapor barriers, and many other structural components and stored items. They can chew and gnaw entry holes anywhere from the ground to the roof and only need an opening of a 1/4″ to 1/2″ to gain access to places like your attic and crawlspaces. This is why it’s important to get effective rodent exclusion if your home or business has an infestation. The gallery below illustrates all the various things rats and mice can chew through to gain entry into your home.
