Pest activity changes throughout the year, and what affects your home in summer may be very different to the issues that appear in winter. Understanding seasonal pest patterns helps homeowners stay ahead of infestations, reduce damage and avoid unexpected pest control call-outs.

Across Victoria, seasonal weather conditions directly influence pest behaviour. Knowing what to watch for each season allows you to take preventative action before pests become a problem.

Summer Pest Risks for Homes

Summer is peak pest season for many households. Warmer temperatures and increased insect activity draw pests into homes in search of food, water and shelter.

Common summer pests include:

  • Ants entering kitchens and pantries

  • Cockroaches in warm, humid areas

  • Spiders following increased insect populations

  • Mosquitoes around outdoor areas

  • Wasps nesting in eaves and trees

Open doors, outdoor dining and higher humidity make it easier for pests to move indoors during summer.

Autumn Pest Activity in Residential Properties

As temperatures begin to cool, many pests look for shelter. Autumn is often when rodents become more noticeable as they seek warmth and food sources inside homes.

Homeowners should watch for:

  • Rats and mice entering roof voids and garages

  • Increased rodent activity near bins and sheds

  • Spiders settling into roof spaces

  • Ants seeking stable food sources indoors

This is an ideal time for preventative pest control before winter sets in.

Winter Pest Problems to Be Aware Of

Winter does not eliminate pests, but activity often becomes less visible. Many pests remain active inside walls, ceilings and roof voids.

Common winter pest issues include:

  • Rodents nesting in roof spaces

  • Cockroaches hiding in warm internal areas

  • Spiders remaining in garages and sheds

Because pests are less visible, winter infestations often go unnoticed until numbers increase again in spring.

Spring Pest Activity Around the Home

Spring signals the return of increased pest movement as temperatures rise. Many pests begin breeding during this period, leading to population growth.

Spring pests commonly include:

  • Ants becoming active again

  • Spiders increasing in number

  • Flies around outdoor areas

  • Wasps beginning to build nests

Early spring treatments can prevent major infestations later in the year.

Why Seasonal Pest Control Matters

Relying on reactive pest treatments often leads to recurring issues. Seasonal pest control focuses on prevention, reducing the risk of infestations before they escalate.

Benefits of seasonal pest control include:

  • Fewer emergency call-outs

  • Reduced property damage

  • Better protection for families and pets

  • More consistent, long-term results

Homes that receive regular pest control tend to experience fewer pest problems year-round.
