Signs Your Home Has Pests | Wellington Pest Control Guide

Prevention is essential to keeping your home safe and pest-free. Spotting the early warning signs of common household pests allows you to take action before an infestation causes structural damage or health risks on your property.

Rodents (Rats & Mice)

Droppings: Fresh droppings are black and shiny; old droppings turn dry and gray. Mouse droppings are rice-sized, while rat droppings are 3–4 times larger. Droppings turn light brown if rodents consume pet food.
Hotspot Nesting: Check roof cavities, hot water cupboards, kitchen pantries, under ovens, and behind refrigerators (where motor compartments supply warmth and drain trays supply water).
Structural Signs: Look for gnawed holes at wall bases, chewed carpet edges along door gaps, chewed bottom door frames, and strong ammonia urine odors.
Action: Arranging professional rodent control prevents rapid nesting expansion.

Ants

Exterior Trails: Outdoor worker ants form active trailing lines along foundation walls and property corners to bring food back to the queen.
Indoor Grit: Piles of lightweight, dark grit (comprised of body parts from eaten insects) accumulate on windowsills, room corners, and furniture.
Entry Points: Grit frequently drops from ceiling recessed lights, joinery gaps, and wall voids.
Action: Applying targeted ant treatments destroys the entire colony at the nest level.

Spiders

Web Build-Ups: Look for dense webbing around exterior windows, outdoor lights, cladding crevices, high interior corners, and inside dark cupboards or drawers.
Nomadic Species: Whitetail spiders do not build traditional hunting webs; they construct temporary, wispy silk sacs in dark spots when preparing to lay eggs.
Action: Perimeter spider extermination services manage both web-building and hunting species.

Flies

Winter Spotting: Clusters of pinhead-sized brown fecal dots appear on ceilings, walls, door frames, light fittings, and smoke detectors (which can trigger false midnight alarms).
Summer Swarms: Warm Wellington weather accelerates breeding cycles beyond what natural predators can control.
Action: Implementing proactive fly control maintains a hygienic living environment.

Carpet Moths & Carpet Beetles

Carpet Damage: Bald patches ranging from 2 cm to 40 cm wide in wool carpets, concentrated along baseboards, under heavy furniture, and in low-traffic rooms.
Cocoons & Moths: Small 10 mm white silk cocoons hanging near curtains or cornices, accompanied by 15–20 mm brown and white adult moths.
Gradual Spread: Because adult moths lay eggs in the same carpet where they fed as larvae, infestations spread slowly across rooms over several years.
Action: Applying carpet beetle and moth treatments prevents permanent fiber degradation.

Wood-Boring Beetles (Borer)

Flight Holes: Clean 1–2 mm circular exit holes visible in exposed timber, structural subfloors, or weatherboards.
Dust Accumulation: Piles of fine, flour-like wood dust (frass) settling beneath affected timber or trailing down vertical timber faces.
Timber Weakness: Spongy or crumbling timber edges along joists and floorboards.
Action: Booking active borer treatments protects structural timber integrity.

Cockroaches

Fecal Specks: Dark, pepper-like specks or smudges along cabinet hinges, under sinks, and behind kitchen appliances.
Egg Cases & Odor: Small brown capsule-shaped egg cases (oothecae) in dark drawers, accompanied by a damp, musty odor.
Action: Implementing professional cockroach control eliminates harbourage zones.

Fleas & Bedbugs

Flea Signs: Small black specks (“flea dirt”) in pet bedding that dissolve into red rings when wiped with a wet paper towel, paired with ankle bite clusters.
Bedbug Signs: Rust-colored blood spots or dark fecal specks along mattress piping, seams, and headboard crevices.
Action: Early intervention via bedbug extermination or specialised flea treatments stops severe bites.
