If you’ve noticed more spiders around your home during summer, you’re not alone. Warmer weather across Victoria leads to a noticeable increase in spider activity, particularly in homes, garages, sheds and outdoor living areas.

While most spiders are harmless, increased sightings can be unsettling and may indicate other underlying pest activity. Understanding why spiders appear more often in summer can help homeowners reduce spider presence and decide when professional pest control is needed.

Why Summer Brings More Spiders Indoors

Spiders become more active during warmer months due to increased insect populations and favourable breeding conditions. Summer weather provides:

  • Higher temperatures that speed up spider activity

  • An abundance of insects for food

  • Dry outdoor conditions that push spiders towards cooler, sheltered spaces

Homes offer ideal hiding spots such as roof voids, wall cavities, garages and sheds.

Increased Insects Mean Increased Spiders

Spiders follow their food source. During summer, insect populations such as flies, mosquitoes and moths increase significantly. If these insects are present around your home, spiders are likely to follow.

Seeing spiders indoors often indicates that other pests are already active on the property, even if they are not immediately visible.

Common Areas Where Spiders Settle in Homes

Spiders tend to favour quiet, undisturbed areas, including:

  • Roof spaces and ceiling corners

  • Garages and storage rooms

  • Sheds and outdoor structures

  • Window frames and doorways

  • Under outdoor furniture and eaves

Webs in these areas often increase during summer months.

Are Summer Spiders Dangerous?

Most spiders found in Victorian homes are not dangerous and will avoid human contact. However, some species can deliver painful bites and should be managed carefully, especially in homes with children or pets.

Even harmless spiders can cause anxiety and create an untidy appearance if left untreated.

Why DIY Spider Control Is Often Ineffective

Surface sprays and DIY treatments may remove visible spiders but do not provide lasting control. Spiders often return because:

  • Residual protection is limited

  • Entry points are not addressed

  • Insect populations remain untreated

Without controlling both spiders and their food sources, infestations can continue throughout summer.

How Professional Spider Control Helps

Professional spider pest control focuses on:

  • Treating common spider harbourage areas

  • Applying long-lasting residual barriers

  • Reducing insect activity that attracts spiders

  • Sealing and managing entry points

This approach provides more reliable, long-term results than DIY treatments.
