How Water Damage Increases Your Risk of a Mouse Infestation and What to Do Next

Water damage is already a headache on its own. However, there’s something most homeowners don’t consider when they’re mopping up after a leak. Sure, water damage affects your home’s structure, but it can also roll out the red carpet for little rodent invaders: mice.

Mice Love the Results of Water Damage

Mice are always looking for the path of least resistance. Healthy, solid construction gives them very little to work with, but water-damaged wood is a different story.

When wood absorbs moisture, it swells, warps, and begins to rot. What was once a tight seal around a window frame or a door threshold becomes soft and easy to penetrate. Mice don’t need much to slip past your barriers, and rotting wood is easy to gnaw through, even if there’s not a hole there yet.

Beyond the physical damage to your home, water creates humidity. Damp basements, crawl spaces, and wall cavities hold moisture that draws rodents in search of a drink. Mice don’t need much water to survive, but they do need a reliable source of it, and a home with ongoing moisture issues definitely fits the bill.

Nesting Material

Water damage usually leads to another problem that mice appreciate more than you’d think: damaged insulation and drywall. Wet insulation falls apart fast, and once it starts to break down, it’s a great nesting material. Mice tear it apart, burrow into it, and settle in for the long haul. The same thing goes for crumbling drywall.

Time Is Not on Your Side

One of the biggest issues with water damage is that time’s not on your side. There’s a great chance that, while you repair the visible water damage at the surface, mice are already hard at work exploiting what’s happened inside the walls or under your floors. By the time you’re hearing scratching in the walls or finding droppings in the pantry, the infestation is already established.

Defending Your Home

Start by inspecting any areas that have been damaged by water for signs of wood rot, compromised seals, or gaps that weren’t there before. Pay special attention to anywhere pipes enter walls, around windows and doors on lower levels, and in crawl spaces or unfinished basements. Look for the telltale signs of mouse activity, like droppings and grease trails along baseboards.

Repair the water damage right away, and dig deep to make sure you get what’s damaged beyond the surface. A little paint does not make a real repair.
