As summer draws to a close and temperatures decrease, an uptick in house spider sightings is being reported across the UK. Experts explain that this is the peak mating season for many common house spiders, prompting mature males to leave their usual habitats in search of females.
The increased movement of these spiders, combined with open doors and windows during the warmer final weeks of summer, makes it more probable for them to enter residential spaces. According to window experts at SolarFrame, a single female house spider can produce an egg sac containing approximately 70 young spiders. The ease with which male spiders can access homes directly correlates with the potential for more egg sacs to be laid within living areas.
Homeowners can implement several measures to deter spiders. Closing windows, particularly around dusk when it begins to get dark, can eliminate a common entry point. Experts from Fluid Glass note that spiders are not primarily attracted to homes for warmth, but rather for a food source. Homes with abundant insect populations, often due to uncovered food, accumulated waste, or unemptied recycling bins, act as attractive feeding grounds for spiders.
Preventing Spider Entry
Making homes less inviting to spiders involves managing insect populations and disrupting their habitats. Moving furniture away from walls during cleaning can help dismantle existing webs and egg sacs, discouraging spiders from establishing long-term residences. Reducing clutter in areas like garages, lofts, and utility rooms also removes natural hiding spots.
Gardens can also contribute to spider ingress. Climbing plants, overgrown shrubs, and dense vegetation near doors and windows can create pathways for spiders and attract the insects they prey on. Trimming plants away from exterior walls, storing firewood away from the house, and clearing garden debris can establish a barrier between outdoor habitats and living spaces.
Damp areas such as bathrooms, kitchens, and utility rooms are often favored by spiders due to humidity and the presence of other insects. Poor ventilation and condensation can create environments conducive to pests. Addressing leaks promptly and using extractor fans can make these areas less appealing.
Additionally, experts advise reconsidering outdoor lighting. Bright lights near entry points can attract moths and other flying insects, which in turn draw spiders. Switching to warmer, dimmer bulbs or installing motion sensors can reduce the constant attraction. Repositioning lights so they do not shine directly onto doors and windows can also help prevent insects and spiders from congregating at entry points.
