Summer nights may begin warm, but when the sun sets behind Mount Timpanogos, temperatures can drop by 30 degrees or more. As you reach for a blanket, spiders are also doing the same thing; they are just coming directly to your home. Those eight-legged guests are not coming in there by coincidence.
Spiders are in search of Orem’s explosive nighttime temperature changes, and your bedroom provides the three characteristics that appeal most to them: heat, shelter, and, surprisingly, abundant food supplies. If you have noticed spiders increasing their presence around your bed, there is a good reason: the weather in Utah County. If spider activity has gotten out of control, contacting a pest professional in your area can help you keep your home pest free in Orem.
How Orem’s Rapid Nighttime Temperature Drops Affect Spider Behavior
Orem is a bit above 4,774 feet, so well, climate control operates somewhat differently here than in most low-lying cities. Orem local climate data shows during late summer and early fall a difference of 25-35 degrees between afternoon highs and nighttime lows. As spiders are cold-blooded, once exterior temperatures plummet quickly after sunset, their metabolism slows significantly. This makes them slow and easy targets for predators.
That survival instinct kicks in strong; they start pursuing thermal refuges, and your heat-filled home shines like a lighthouse. The difference between the air in your bedroom (which is usually between 68–72 degrees) and the outdoor air creates an actual heat signature that literally attracts spiders through cracks in your foundation, gaps in your windows, and thresholds of your doors.
Why Bedrooms Become Prime Spider Spots (More Than Other Rooms)
It is not only that bedrooms are warmer, but also darker, quieter, and receive less foot traffic at night than living rooms or kitchens. Spiders like undisturbed spaces where they can stalk their prey. Other minor bugs that spiders prey on live in your bedroom as well, such as dust mites and carpet beetles.
Closets, under beds, and corners around baseboards make ideal construction sites. There are also more textiles in a bedroom (curtains, bedding, carpets) that attract the prey insects spiders hunt, creating a complete food chain in your sleep space.
Household Habits That Accidentally Invite Spiders Indoors
You may be inviting spiders into your home without even knowing it. Common habits include:
- Leaving windows cracked at night – As refreshing as those cool evening breezes are in Orem, those gaps are spider superhighways into your home.
- Clutter near foundations – Outdoor stacks of firewood, storage bins, and gardening supplies against outside walls provide stepping stones for spiders to enter buildings
- Inconsistent door sweeps – During colder weather, many Orem homes have gaps under doors that allow spiders to come right through.
- Outdoor lighting near entries – Moths and other insects swarm porch lights, and hunting spiders follow the food source right to your doorstep
- Infrequent vacuuming in corners – Untouched nooks are ideal for spider eggs and webs, letting populations grow
Local Pest Pros Who Know Orem’s Nighttime Spider Patterns
Given the Wasatch Front’s topography, some microclimates affect spider behavior in Orem, Salt Lake City, and/or Provo. For years, companies like Saela Pest Control have been tracking spiders’ movement through Utah County neighborhoods in response to subtle seasonal temperature changes. And they know hobo spiders and wolf spiders, the two most frequent nighttime visitors to Orem bedrooms, begin to buzz about, especially during September and October when our nighttime lows are finally flirting with the 40s.
Furthermore, their technicians know it is better to treat the exterior perimeter before spiders move inside, rather than evicting your home and treating the living room, or else the rec room converts into a bedroom corner. Generic pest control approaches found across the US do not account for the unique behavior patterns of homes nestled along the Wasatch Range foothills, which are predominantly driven by altitude, so local expertise matters.
