Top 5 Pests That Are Most Likely to Invade Your Home This Season

As the seasons change, so does pest activity. Each time of year brings different environmental conditions that can make your home more vulnerable to specific types of pests. Whether it's the warmth and moisture of summer, the chill of winter driving insects indoors, or spring rains creating breeding grounds, pests will find their way in if given the opportunity.

In this article, we highlight the top five pests most likely to invade your home this season, the warning signs to watch for, and practical tips to prevent infestations before they take hold.

1. Ants

Why they're active now: Ants are most active during the warmer months, especially spring and summer. As temperatures rise, ants venture indoors in search of food, water, and shelter—often building colonies near kitchens and bathrooms.

Common ant species:

• Black house ants

• Argentine ants

• Coastal brown ants

• Carpenter ants (which can cause structural damage)

Signs of an infestation:

• Trails of ants along walls, countertops, or floors

• Small piles of dirt or sand near cracks or baseboards (entry points)

• Rustling noises in walls (in the case of carpenter ants)

Prevention tips:

• Keep food sealed and floors free of crumbs

• Wipe up spills promptly, especially sugary substances

• Seal cracks around windows, doors, and baseboards

• Remove standing water or leaky taps

Why it matters: While most ants are more of a nuisance than a threat, some species like carpenter ants can damage wood, and all ants can contaminate food.

2. Cockroaches

Why they're active now: Cockroaches thrive in warm, humid environments and often invade homes during summer and spring when they’re searching for food and moisture. Once inside, they multiply quickly and are notoriously difficult to eliminate.

Common cockroach species:

• German cockroach (common in kitchens and bathrooms)

• American cockroach (often found in basements and drains)

• Australian cockroach (prefers humid, warm spaces)

Signs of an infestation:

• Live or dead cockroaches, especially at night

• Musty or oily odor

• Droppings that resemble pepper flakes or coffee grounds

• Egg casings (oothecae) in hidden corners

• Smear marks on walls near water sources

Prevention tips:

• Store food in airtight containers

• Take out the rubbish daily and clean bins regularly

• Fix plumbing leaks and reduce moisture

• Clean behind appliances and avoid clutter

Why it matters: Cockroaches are known to spread bacteria like Salmonella and E. coli. They can also trigger asthma and allergies, especially in children and the elderly.

3. Rodents (Rats and Mice)

Why they're active now: Rodents seek shelter, warmth, and food throughout the year, but their activity often peaks during colder months and in urban areas where food is easily accessible.

Homes offer a safe nesting site with plenty of resources.

Signs of a rodent infestation:

• Droppings (pellet-shaped for mice, larger for rats)

• Scratching or scurrying noises in walls or ceilings

• Chewed wires, packaging, or furniture

• Nests made from paper, fabric, or insulation

• Greasy rub marks along walls or skirting boards

Prevention tips:

• Seal all holes and cracks around your home’s exterior

• Store pet food and grains in rodent-proof containers

• Keep clutter to a minimum in storage areas

• Set traps in areas with suspected activity

Why it matters: Rodents can cause significant structural damage, chew through electrical wiring (increasing fire risk), and spread diseases like hantavirus, leptospirosis, and salmonella.

4. Termites

Why they're active now: Termites are particularly active in warm and moist conditions, making late spring and summer prime time for swarming and nesting. Subterranean termites, common in many parts of Australia, seek out damp soil near home foundations and build tunnels to access wooden structures.

Signs of a termite infestation:

• Mud tubes on walls or foundations

• Hollow-sounding wood

• Discarded wings near windows or doors

• Bubbling paint or warped walls (often mistaken for water damage)

• Frass (termite droppings) that look like small wood pellets

Prevention tips:

• Fix leaking pipes and ensure proper drainage around your home

• Keep firewood and mulch away from the house

• Use treated wood for decks and fences

• Schedule annual termite inspections with a licensed professional

Why it matters: Termites cause billions in property damage globally each year. Their destruction is often hidden and not covered by standard home insurance policies, making early detection and prevention critical.

5. Spiders

Why they're active now: As other insects become more active in warm months, spiders follow their food sources indoors. While most common household spiders are harmless, some species—like the redback spider—can be dangerous.

Common spider species:

• Redback spider (venomous)

• White-tailed spider

• Huntsman spider

• Daddy long legs

Signs of a spider problem:

• Webs in corners, ceilings, or around windows

• Frequent sightings in bathrooms, garages, or basements

• Egg sacs in undisturbed areas like storage boxes

Prevention tips:

• Keep the home clean and dust regularly

• Declutter garages, attics, and storage spaces

• Seal cracks and gaps in doors and windows

• Shake out shoes and clothing left on the floor

Why it matters: While most spiders help control other pests, some can deliver painful or venomous bites. Frequent spider sightings may also indicate another pest issue, such as an abundance of flying insects attracting them indoors.

General Prevention Strategies for All Pests

Regardless of the season or pest type, here are some universal practices to help protect your home year-round:

1. Seal Your Home: Use weatherstripping, caulk, and mesh screens to block entry points.

2. Reduce Moisture: Fix leaks, use dehumidifiers, and ensure proper ventilation.

3. Practice Good Hygiene: Regularly clean floors, counters, and food preparation areas.

4. Manage Waste: Keep bins sealed and dispose of rubbish promptly.

5. Store Food Properly: Use airtight containers and avoid leaving pet food out overnight.

6. Schedule Regular Inspections: Early detection by a pest control professional can prevent small problems from becoming infestations.
