A single family of mice can produce over 100,000 offspring in just one year.
If you live in the western suburbs of Chicago, you might have noticed an uptick in mouse activity this year. You're not alone—EcoGuard Pest Control has observed a significant increase in mouse populations compared to the last few years. We believe that the emergence of two large cicada broods this spring provided an abundant food source, contributing to this population boom.
Cicadas as a Food Source for Mice
Cicadas are not just a noisy summer nuisance; they also serve as a rich food source for various animals, including mice. This year’s dual emergence of large cicada broods created a buffet for the local mouse population. As the cicadas died off, their bodies became easy pickings for mice, which are opportunistic feeders. This surge in available food likely supported the growth and reproduction of the mouse population, leading to the increased activity we’re now seeing in homes across the region.
Our technicians have even found evidence of this firsthand. During inspections and treatments, they have discovered cicada body parts near mouse nest sites within homes. These remnants are a clear indicator that the mice have been feasting on the cicadas, which has helped them thrive and multiply.
With the colder months approaching, these well-fed mice are now seeking warm, sheltered places to nest—often inside our homes. Here’s what you need to know about identifying a potential mouse problem and how to make your home less inviting to these unwelcome guests.
How to Identify a Mouse Problem
Mice are sneaky and can enter your home through the smallest of openings. Here are some tips to help you spot signs of a mouse infestation:
Droppings: Mouse droppings are small, dark, and about the size of a grain of rice. You may find them near food sources, in cabinets, or along baseboards.
Gnaw Marks: Mice have strong teeth and will gnaw on anything from wood to plastic. Check for gnaw marks on food packaging, wires, and wooden structures.
Nests: Mice build nests out of soft materials like paper, fabric, and insulation. These are often hidden in secluded areas like attics, basements, or behind appliances.
Scratching Noises: If you hear scratching or scampering noises in the walls, especially at night, you may have a mouse problem.
Tracks and Smudges: Mice tend to follow the same paths, leaving behind greasy smudge marks along walls and floors. You might also see small footprints in dusty areas.
Preventative Measures Around Your Home
Keeping mice out of your home starts with making the exterior of your property less appealing. Here are some steps you can take:
Seal Entry Points: Mice can squeeze through openings as small as a dime. Inspect your home’s exterior for cracks, gaps, or holes, especially around doors, windows, and utility lines. Seal these with caulk or steel wool.
Eliminate Food Sources: Keep garbage in sealed containers, clean up any pet food, and avoid leaving birdseed or other food sources outside.
Trim Vegetation: Mice love to hide in tall grass, shrubs, and piles of leaves. Keep your yard tidy by regularly trimming vegetation and removing any debris.
Store Firewood Properly: If you store firewood outside, keep it at least 20 feet away from your home and elevate it off the ground to prevent mice from nesting.
Install Door Sweeps: Install door sweeps on exterior doors to block the gap between the door and the threshold.
Remove Water Sources: Mice need water to survive. Fix any leaky faucets, hoses, or pipes around your home to cut off their supply.
By following these tips and staying vigilant, you can reduce the risk of mice making your home their winter refuge.
