A vacant home offers everything pests need: shelter, darkness, undisturbed nesting areas, and no human activity to deter them. Mice enter through gaps left unchecked, spiders build webs in every corner, pantry moths breed undetected in forgotten food, and moisture builds to levels that attract silverfish, centipedes, and mold mites.
Whether you own a lake house, mountain cabin, beach condo, or snowbird property, two protocols prevent most problems: a closing checklist when you leave and an opening checklist when you return.
Remove all food. Every crumb, every opened package, every forgotten bag of rice. Pantry moths and grain weevils can establish breeding populations in a single forgotten bag of flour over a few months. Freeze or take home anything you can't seal in glass or metal containers.
Clean thoroughly. Sweep, vacuum, and wipe down all surfaces. Crumbs behind the stove and under the fridge sustain cockroach and ant colonies for months. Empty all trash and recycling.
Seal entry points. Walk the exterior and seal any new gaps with copper mesh and silicone caulk. Check the garage door seal, dryer vent flap, and all utility penetrations. This is your most important step — our exclusion guide covers the priority areas.
Set rodent traps. Place snap traps along walls in the garage, basement, kitchen, and attic. Use peanut butter or a small piece of Slim Jim as bait. Traps catch early intruders before they establish nesting.
Apply long-lasting treatment. CimeXa dust in wall voids and behind outlet covers provides years of protection against crawling insects. A bifenthrin perimeter spray around the foundation lasts 60–90 days.
Address moisture. Set the thermostat to 55°F minimum (prevents pipe freeze and excessive humidity). Run a dehumidifier on a timer or set to auto. Leave bathroom doors open for air circulation. A damp, unventilated house breeds mold mites and attracts moisture-dependent pests.
Place monitoring traps. Glue boards in the basement, kitchen, and attic serve as intelligence — when you return, they show exactly what's been active in your absence.
Check monitoring traps first. What's on the glue boards tells you what happened while you were away. Mouse droppings near traps, spider captures, cockroach activity — this guides any treatment you need to do before unpacking.
Inspect for rodent activity. Walk the entire home looking for droppings, gnaw marks, nesting material (shredded paper, insulation, fabric), and urine stains. Check attic insulation for displacement. If you find droppings, follow the CDC cleanup protocol before disturbing anything.
Run all water. Flush toilets, run sinks and showers for 2 minutes each. This refills P-traps in drains that may have dried out — dry P-traps allow sewer gas and drain flies to enter from the sewer line.
Check stored items. Inspect mattresses for bed bug evidence (blood spots, fecal dots) and closets for clothes moth damage (holes in wool or silk, silken tubes in fabric folds).
Ventilate. Open windows for 30 minutes to flush stale air and reduce any chemical or mold odors that built up.
Property management check-ins: If possible, arrange monthly walk-throughs by a property manager or neighbor — even 15 minutes checking traps, running water, and looking for signs of intrusion prevents small problems from becoming large ones.
Quarterly pest control service: Many pest control companies offer vacant-property plans at reduced rates. These typically include perimeter treatment, rodent station maintenance, and termite monitoring — particularly valuable for properties in termite-prone regions.
Smart home monitoring: Water leak sensors, humidity monitors, and even motion-activated cameras in the garage or basement alert you to problems before your next visit.
