When mice infest attics and walls, their urine causes permanent musty odors. The damage they cause by tunneling through insulation reduces its energy efficiency. And the diseases they carry, including salmonellosis and leptospirosis, are transmissible to humans.

Solving Rodent Problems in Illinois through Green Pest Control Solutions

Most mouse problems are caused by structural deficiencies that allow mice to enter buildings. Mice dart under exposed doors, climb across power lines and enter where flashing is inadequate and where gaps around pipe chases permit them to crawl inside. Gaps as small as a quarter inch provide enough access for rodents to infiltrate your building. Even small unprotected openings are an invitation to mice. Finding and correcting these deficiencies is key to solving mouse problems and reducing reliance on rodenticides. Sealing gaps to build mice out is the best long-term solution to mouse infestation. Through trapping and sealing gaps to build mice out, most mouse infestations can be resolved without the use of rodenticides.

Gaps beneath doors need to be protected through the use of door sweeps that are specially constructed to keep mice out. Many buildings are equipped with inadequate bristle-style door sweeps that are designed to reduce entry by insects, but these do little to exclude mice, since rodents can chew or part their soft bristles. Landmark installs rodent-proof door sweeps that feature metal fibers encased in a bulb of weather stripping. These durable sweeps prevent both mice and drafts from passing beneath the door.

The liberal use of rodenticides to control mice means that mice poisoned by rodenticides become easy prey for birds of prey and other wildlife, making these products a danger to hawks, owls, coyotes and other non-target wildlife.

Mice are excellent climbers and they often enter buildings at the roof level. When mice are discovered, a thorough inspection should include checking attic spaces, areas where power lines and data enter, around ducts and vents, and laundry drains.

Fires Caused by Rodents

According to the Illinois Department of Public health, it is estimated that rodents likely start 25 percent of all fires attributed to unknown causes.

The propensity of rodents to build their nests near warmth means that they will drag combustible nesting materials to areas on top of steam pipes and near vents that may become quite hot leading the flammable nesting materials to combust. Mice are particularly at risk of filling voids around pipes with flammable materials when any length of the pipe passes between two floors and forms a cavity.

Rats are also able to contribute to fires and explosions by gnawing gas lines and causing gas leaks.

Two modern safety improvements have reduced the number of fires caused by rodents chewing.

First, strike-anywhere friction matches called Lucifers have been replaced by safety matches that keep the combustible elements separate until the match head is drawn across a special lighting strip. Friction matches were frequently found in rodents’ nests and were ignited by their bite. Many fires were attributed to mice and rats having ignited matches that they had carried off to their caches beneath floors or in walls.

The other modern improvement that has cut down on rodent-related fires is the updated building codes that mandate conduit pipes enclose electrical wires. While rodents still cause thousands of home fires by accessing wiring in open junction boxes, electrical panels, cords, and other vulnerable areas, having most of a building’s wiring in conduit certainly reduces rodent access.
