Damage Patterns You Can See

Look for blistered paint, rippling veneer, pin-sized exit holes, and sagging trim that suddenly sounds hollow. These clues often appear near baseboards, crawlspace joists, or damp window frames. Snap photos, mark dates, and compare weekly to catch changes early and confidently.

Frass, Wings, and Dust

Powderpost beetles leave talc-like frass sifting from pinholes, while termites leave discarded wings near windows after swarms. Carpenter ants push out coarse sawdust-like debris. Keep a white card under suspicious wood for a week; any new fall-out is a powerful diagnostic hint.

Listening, Tapping, and Even Smelling

Gently tap wood with a screwdriver handle and listen for hollow, papery echoes. In quiet rooms, you may hear faint rustling from active galleries. Some infestations carry a slightly musty odor. Trust your senses, then verify with a flashlight and a probing awl.

Know the Culprits: Who Eats, Bores, and Nests in Wood

Subterranean termites build pencil-thin mud tubes along foundations to maintain moisture as they travel. Drywood termites live entirely inside wood, producing small, sand-like pellets. Swarmers appear in warm seasons after rain. A single overlooked tube can feed an entire colony for months.

Know the Culprits: Who Eats, Bores, and Nests in Wood

Carpenter ants do not eat wood; they excavate smooth tunnels for nesting, often in damp spots near leaks. Carpenter bees bore round entrance holes in exposed softwoods, leaving yellowish staining. Night lighting can attract foraging ants; dimming or relocating lights helps disrupt traffic.

Know the Culprits: Who Eats, Bores, and Nests in Wood

Powderpost beetles thrive in unfinished hardwoods, leaving tiny holes and fine powder. Woodworm, a casual term for various borers, favors older, moisture-prone timbers. Fresh, bright frass suggests active infestation; darkened, compacted frass often indicates old, inactive damage. Confirm with periodic vacuum tests.

Moisture Mastery: Prevent Pests by Controlling Dampness

Repair dripping pipes, clogged gutters, and downspouts that dump water near foundations. Extend leaders at least six feet from walls. Grade soil so it slopes away. A single afternoon of drainage fixes can cut pest pressure dramatically and protect joists for years.

Moisture Mastery: Prevent Pests by Controlling Dampness

Aim for indoor relative humidity between 30% and 50%, with crawlspaces below 60% if possible. Add vent fans in bathrooms, ventilate attics, and consider a dehumidifier near stored lumber. Dry air discourages termites, ants, and beetles from settling in and expanding galleries.

Seal Gaps, Screens, and Entry Routes

Caulk cracks around windows and siding, add stainless steel mesh to weep holes, and install door sweeps. Screen attic and crawlspace vents. Even a quarter-inch gap can invite carpenter ants. A weekend of sealing often yields years of quieter, safer baseboards and beams.

Borate Treatments and Safer Options

Borate solutions penetrate raw wood, deterring termites and beetles while remaining low in odor. Brush or spray onto accessible framing and unfinished furniture. Reapply to exposed surfaces if heavy rain occurs. Always follow labels, and test a small area to prevent unwanted discoloration.

Mulch, Firewood, and Perimeter Practices

Keep mulch layers thin and a few inches away from siding. Elevate firewood on racks, not directly on soil. Avoid burying wood scraps near foundations. These simple perimeter habits starve pests of humidity, reduce scouting opportunities, and keep your inspection paths clear.

Smart Inspections and DIY Monitoring

Set a monthly reminder to scan baseboards, crawlspaces, sill plates, and window sills. In spring, watch for swarmers and discarded wings; in summer, monitor exterior eaves for round bee holes. A checklist turns vague worry into clear, confident action you can repeat easily.

Smart Inspections and DIY Monitoring

Place termite monitoring stakes near downspouts and shady corners. Tape white index cards beneath suspect beams to catch fresh frass. Keep a flashlight, awl, and measuring tape in a small tote. These inexpensive tools help you notice changes and react before damage accelerates.

A True Tale: The Cabin That Stopped the Swarm

After a warm, rainy weekend, dozens of winged termites appeared on a sunny windowsill. The owner heard faint tapping in a quiet hallway at dusk. Panic set in, but photos, bagged wings, and a calm checklist turned chaos into a clear, doable set of next steps.

A True Tale: The Cabin That Stopped the Swarm

They fixed a gutter elbow, extended downspouts, and added a vapor barrier in the crawlspace. Mud tubes were scraped and monitored weekly. Borate was applied to exposed joists, and firewood moved forty feet away. Within three weeks, no new tubes appeared, and humidity dropped meaningfully.
