Homeowners and business owners can take some common-sense measures to prevent rat infestations, including keeping pet food containers and garbage containers tightly sealed and the areas around them picked up and clean.

Bird feeders also are attractive to rats. Another of our customers, who had multiple bird feeders in her backyard, noticed that the seed-covered bird bell she hung in one corner of her yard would repeatedly disappear almost overnight. She would replace it, and by the next morning, it would be eaten down almost to the plastic hanger. Hungry birds, she thought. Then one evening, she happened to be looking out the back door just as dark was settling in and heard a rustling in the leaves above the bird bell. Grabbing a flashlight, she quietly walked over to investigate. The beam of the flashlight revealed an acrobatic roof rat, hanging upside down from the branch, nibbling away.

Storing wood off the ground and eliminating clutter and debris from around building foundations also will discourage rat activity. Roof rats, such as the acrobat caught eating our customer’s bird bell, may use overhanging tree branches, pergolas or dense shrubbery such as star jasmine or ivy as a highway to your roof, where they may find entry to your attic around eaves, pipes or chimney flashing. Trimming trees to leave 2 feet or more between plants and between branches and roof helps discourage these travels. Sealing, screening or plugging openings around wiring conduit or pipes with steel wool or sheet metal, both around your roofline and at foundation level, also are effective at keeping rats out.

Once rats have moved in to your home or place of business, the best way to eliminate them is with the traditional snap traps. A major infestation may require the use of poison bait, which should only be administered by a trained pest control professional. Although customers sometimes request it, the use of live traps is not a good idea. Because the rats are not native to our environment, they cannot be released outdoors, where they pose a danger to humans, pets and property and—because they are an invasive species—to the native ecosystem. In some areas, rats have been known to decimate wild bird populations. Live traps also accumulate bodily waste from the rodents, creating a health hazard for our pest control technicians.
