Every pest control operator has seen it: a family moves into a clean home and within weeks has cockroaches, bed bugs, or carpet beetles — all hitchhiked from the old house in moving boxes, furniture, and stored items. Moving is the #1 way pests spread between homes, and a few precautions prevent it entirely.
Purge aggressively. Every item you don't move is one less pest vehicle. Cardboard boxes stored in basements and garages are cockroach habitat and silverfish food — discard them rather than packing them. Old clothing stored in attics may harbor clothes moths or carpet beetles.
Inspect furniture. Before loading furniture onto the truck, check mattress seams and headboards for bed bug evidence. Check upholstered furniture seams and underneath. Check wooden furniture joints for powderpost beetle exit holes (tiny round holes with fine dust).
Wash all textiles. Run all clothing, bedding, curtains, and linens through a hot dryer cycle (130°F for 30 minutes) before packing. This kills bed bugs, moth larvae, and carpet beetle larvae on fabrics.
Use plastic bins, not cardboard. New sealed plastic bins for packing eliminate the cardboard habitat that cockroaches, silverfish, and spiders prefer. If you must use cardboard, use new boxes — not recycled ones from grocery stores (which may carry cockroach eggs).
Inspect the truck. If using a rental truck, check corners, floor seams, and cargo tie-down points for cockroach or mouse evidence. Moving trucks cycle between households — pests from the previous renter's load can transfer to yours.
Don't load infested items. If you discover pest evidence during packing, isolate and treat those items separately rather than loading them onto the truck with everything else. One infested box in the truck can spread to ten clean ones during transit.
Treat before your stuff arrives. The ideal time for pest treatment in a new home is when it's empty — before furniture and boxes block access to baseboards, corners, and wall voids. Apply CimeXa dust behind outlet covers, along baseboards in the basement and garage, and in kitchen/bathroom cabinet voids. Apply perimeter spray around the exterior foundation. Set mouse traps in the garage, basement, and kitchen.
Seal entry points. Walk the exterior and seal gaps before moving in — it's infinitely easier with an empty house. Focus on the 12 priority exclusion points.
Check the kitchen. Run the 30-minute kitchen protocol before putting food in cabinets. Check under sinks, behind the stove, and inside cabinets for evidence of the previous owner's pest problems.
