Pest control in Minneapolis clusters where the house is trying to stay warm. Mice use rim joists and the same exterior bays that freeze supply lines. If you are opening a wall for a burst, expect droppings. Squirrels in a bungalow soffit add bypasses that worsen ice dams. Rats are less the story than mice that stay all winter. Roaches show up where water and a shared wall allow them. Night noise versus a daytime kitchen sighting changes the animal.
The map is droppings at the rim, a rub mark at the garage sweep, a gnawed dishwasher line, and attic scratching after the furnace has run for hours. A raccoon needs a torn eave. Carpenter ants in a wet soffit mean soft wood under the ice dam, not a dirty counter. Silverfish in a clammy basement bath mean moisture. Say which floor. Do not pack every gap in a rim that also needs to keep pipes from sweating and freezing in the wrong order.
Baits have to live with pets and children, so say who uses the rooms. A duplex or a double bungalow can share the problem through a party wall. Treating one kitchen is theater if the neighbor hears them too. Say so. Activity from the first cold week until thaw is an entry, not a visitor. Moisture under a leaky ice dam will keep insects even after the mice are gone. Fold that into the call.
Usual doors are the rim, the dryer vent, the garage sweep, and openings where pipes leave the warm envelope. If you foamed one hole and they returned, name the hole. A return means another opening. Sealing an attic vent to stop flies can worsen the ice dam that is already confusing roof leaks with plumbing leaks. Say if the attic is warm. Say if you are already opening a wall for a frozen line.
Lead with mouse, squirrel, or something in the attic, and name the rim or the soffit. Say if a pipe freeze is happening in the same wall. Minneapolis keeps that wall cold for months. Call the number on this page.
