The Pests That Exploit Garage Conditions
- House Mice The garage is the primary rodent entry point in most Missouri homes. The gap under and around the overhead door, utility penetrations through the garage wall, and gaps at the foundation perimeter all provide access. Once in the garage, mice move into wall voids and from there into the kitchen and living spaces through the interior connection. Snap traps placed along the garage perimeter walls and at the door threshold between garage and house address the mouse population at the transition point.
- Brown Recluse Spiders Garages are prime brown recluse habitat — undisturbed boxes, stored goods, tool storage areas, and the structural wood of an unfinished garage ceiling provide ideal harborage. Brown recluse populations in garages are often larger than those in the house proper. Stored items in cardboard boxes are preferred harborage; plastic bins with lids significantly reduce recluse refuge sites.
- Wasps and Yellow Jackets Overhead door frames, garage ceiling joists, and wall voids accessed through gaps around utility penetrations are common wasp nesting sites. Wasps that nest in garage wall voids often enter the living space through gaps at the garage-house connection. Nests in overhead door tracks are a particular hazard — opening the door disturbs the nest.
- Crickets Garages accumulate crickets in late summer and fall, drawn by shelter and the warmth of the structure. Large cricket populations in the garage draw brown recluse spiders — crickets are a primary recluse food source. Perimeter granular treatment and door gap sealing reduces cricket pressure before it attracts secondary predators.
The Door-to-House Connection
The interior door between the garage and living space deserves the same attention as an exterior entry point — a proper threshold seal, door sweep in good condition, and no gaps around the door frame. This single seal prevents the garage's pest population from freely accessing the house.
