Spring Pest Prevention Checklist for Sydney Homeowners (2025)

Why Spring is Peak Pest Season in Sydney

As Sydney temperatures climb from September onwards, pest activity increases dramatically. Warmer weather triggers breeding cycles, while increased humidity creates ideal conditions for many pest species.

Our platform data shows pest control enquiries increase 45% between September and November compared to winter months. Being proactive now saves you from dealing with established infestations later.

Your Spring Prevention Checklist

Week 1: Exterior Inspection

• ☐ Walk around your home and check for termite mud tubes on foundations
• ☐ Inspect weep holes - ensure they're not blocked (don't seal them)
• ☐ Check for gaps around pipes, cables, and vents entering your home
• ☐ Clear debris, leaves, and mulch from against walls (30cm gap minimum)
• ☐ Move firewood and timber stacks at least 3 metres from the house
• ☐ Trim trees and shrubs touching the building

Week 2: Moisture Control

• ☐ Fix any leaking taps, pipes, or hoses
• ☐ Check air conditioning units for condensation issues
• ☐ Clean gutters and ensure downpipes drain away from foundations
• ☐ Check subfloor ventilation (if accessible)
• ☐ Repair any damaged roof tiles or flashing
• ☐ Ensure bathroom and kitchen exhaust fans work properly

Week 3: Entry Point Sealing

• ☐ Install or repair door sweeps on all exterior doors
• ☐ Check window screens for holes or gaps
• ☐ Seal gaps around utility penetrations with appropriate materials
• ☐ Check garage door seals
• ☐ Inspect roof void access points

Week 4: Professional Inspection

• ☐ Book annual termite inspection before peak swarm season
• ☐ Consider general pest treatment as preventive measure
• ☐ Request inspection of roof void and subfloor if accessible

Termite Swarm Season

Termite swarming season runs from October to March, peaking November-December. During this time, mature colonies release winged reproductive termites (alates) to establish new colonies.

What to Watch For

• Flying termites around lights in the evening
• Piles of discarded wings near windows and doors
• Mud tubes appearing on walls or foundations

If You See Swarmers

1. Don't panic - swarmers themselves don't cause damage
2. Try to capture a few for identification
3. Note where you saw them (may indicate nearby colony)
4. Book a professional termite inspection within 1-2 weeks

Cockroach Prevention

Cockroach activity increases significantly as temperatures rise. German cockroaches in particular breed rapidly in warm conditions.

Prevention Steps

• Store food in sealed containers
• Clean up crumbs and spills immediately
• Don't leave pet food out overnight
• Empty garbage regularly and use sealed bins
• Fix any dripping taps (cockroaches need water)
• Seal gaps around pipes under sinks

Spider Management

Spring triggers spider mating season. While most Sydney spiders are harmless, Funnel-web and Redback spiders require caution.

Reduce Spider Habitat

• Remove web accumulations around windows and eaves
• Clear garden debris, especially near the house
• Shake out shoes, gloves, and outdoor items before use
• Check outdoor furniture before sitting
• Keep garage and shed areas tidy

Rodent Exclusion

As natural food sources increase in spring, rodents may be less visible - but this is the time to prevent them establishing before winter drives them inside.

Exclusion Checklist

• Seal gaps larger than 6mm (mice can fit through very small openings)
• Check roof void for entry points
• Install mesh over vents (keeping adequate airflow)
• Trim tree branches that overhang or touch the roof
• Secure chicken coops and pet food storage

When to Call a Professional

Consider professional pest control if you:

• See any signs of termite activity
• Notice increased cockroach sightings
• Haven't had a termite inspection in over 12 months
• Live in a high-risk area (near bushland, older home)
• Are preparing property for sale

Preventive treatment in spring costs less and is more effective than treating established infestations in summer.
