RELATED: If You’re Not Cleaning This, You’re Inviting Mice Into Your Home. Bird feeders in your yard are a common source of attraction for mice, says Megan Cavanaugh, a pest control expert and co-owner of the pest control company Done Right Pest Solutions in Minnesota. “Nuts and seeds are a favorite food of mice,” she explains. “Mice, like all animals, are always looking for food sources. If you have a food source in or around your home, they are going to be attracted to it.“ae0fcc31ae342fd3a1346ebb1f342fcb According to Cavanaugh, bird feeders also are a high reward-low risk spot for mice to get food. Birds and squirrels that tend to be the target audiences for these feeders are not predators to mice, so these rodents can find food while being relatively safe. The less you clean your bird feeder and around it, the more likely you are to encounter rodents, according to experts. “When eating, the birds can shake the feeder and drop the seeds on the ground. The smell of nutritious seeds will attract unwanted rodents such as mice and rats,” Clarissa Benny, a certified pest control technician and consultant at HouseGrail, says. Tammy Poppie, a bird expert with On The Feeder, says letting your food go bad in your feeder may attract another concerning rodent: rats. “Rats are attracted to moldy seed in the bird feeder,” she says. According to the Centers for Disease Control and Prevention (CDC), you should be cleaning your bird feeder at least monthly, but you might need to clean it more often “as bird poop and other dirt builds up on your feeder.” RELATED: For more pest advice delivered straight to your inbox, sign up for our daily newsletter. According to Benny, keeping your bird feeder higher off the ground can help deter rodents. If your feeder is already well-protected, like in a caged tube, five to six feet off the ground should be sufficient enough. But if you have something like a hopper feeder, it should be kept higher at eight to 10 feet off the ground, she says. You should also keep your bird feeder in the most remote part of your yard to keep any rodents attracted to it as far away from your actual house as possible. “If you place the bird feeder closer than 20 yards to your home, you should pay extra attention to make it hardly accessible for mice and rats,” Benny says. This means making sure the bird food is as inaccessible for mice to get to as possible, no matter where your bird feeder is located. “You can do this by adding obstacles to the bird feeder to make it more difficult for them, or grease the pole that the feeder is on so they can’t climb up it. Also, be sure to trim trees and shrubs from around the bird feeder so they can not climb off of those onto the feeder,” says Sharon Roebuck, owner of pest control company Eastside Exterminators in Seattle, Washington. If you see bird feed scattered all over your yard, this could be a clear sign that mice have already gotten into it and are making their way into your home, according to Roebuck. Benny says you should also check for gnaw marks or scratches on your actual feeder. One other major indicator that rodents have been around is visible droppings and urine. “Droppings are the easiest to spot and the very first sign that you have a rodent problem. You will find them everywhere: around the feeder, in the house, even on your cat’s bowl if they manage to get inside,” Benny says. “Urine is another sign of rodent infestation. Mice have a very specific urine smell that is easy to distinguish.” RELATED: If You Notice This Smell at Home, You May Have Mice, Experts Warn.
