UK homes adopt non-lethal methods to deter indoor spiders

Autumn’s cooler nights have ushered in what pest controllers and homeowners call spider season, as spiders move indoors across the UK in search of warmth, food and mates. Pest UK, one of the country’s oldest independent pest control firms, says the seasonal surge is driven in part by falling temperatures and the mating behaviour of species such as Tegenaria, sometimes called giant house spiders, whose males roam in search of partners.

For households that prefer not to kill spiders, Pest UK outlined four practical, non-lethal strategies to reduce the likelihood of arachnids taking up residence. The first is to make the home a less attractive habitat. Most house spiders favour hidden, undisturbed spaces to wait for prey, so clearing clutter, storing boxes off the floor and regular vacuuming including behind cupboards, in dark corners and under sofas can discourage them, the company said.

The second approach is to block entry points. Spiders can slip indoors through tiny cracks and gaps in walls, around pipework, doors and windows. Pest UK recommends checking and sealing such openings and keeping windows and external doors closed at night when many spiders are most active.
