If you have noticed a number of spiders in your home recently, you are not imagining it. A spike in indoor sightings of spiders can be observed by many Longview homeowners each summer, and the reason is mostly dry weather. Knowing why it happens is the first step to keeping your home spider-free, and knowing when to call in Pointe Pest Control professionals makes all the difference.

Longview’s Summer Climate and What It Does to Local Spider Behavior
Longview is in Colorado’s semi-arid Front Range corridor, where summer rainfall averages less than 2 inches from June to August. Not much moisture, and spiders can sense it, too. As the ground hardens and outdoor water sources evaporate, spiders seek other options.
And that “elsewhere” is often your home. Chill indoor temperatures, reduce condensation on plumbing pipes, and lower basement humidity to turn your house into a welcoming shelter. Spider activity inside Colorado homes, in fact, spikes by 30 percent during drought-heavy summers compared to years with average rainfall. The drier it is outside, the more likely spiders are to move in.
Which Spiders Are Actually Moving Into Longview Homes
Several species that are common in the Longview and Adams County area tend to appear indoors when summer heat peaks:
- Hobo Spider – Likes dark, dry corners; drought drives them further into homes seeking moisture and prey.
- Western Black Widow – Adams County confirmed (dry summer years send them indoors to cool, undisturbed nooks like garages and utility rooms)
- Common House Spider – As they are already adapted to living indoors, their numbers rise when drought conditions decrease the amount of outdoor insect activity near their webs.
- Yellow Sac Spider – Prefers warm, dry environments and often finds its way into homes through wall openings that expand during dry periods.
Where They Are Getting In and Where They Hide
1. Entry Points Dry Summers Worsen
Most homes in Longview were built sometime between the 1970s and the 1990s, and dry summers hasten wear on their vintage exteriors:
- Soil pulls back from foundations, creating gaps on the ground level
- Weatherstripping wears out and cracks more than usual
- The seals on windows shrink, creating small but functional entry points
- Prolonged heat can warp door frames slightly
- Caulk shrivels and falls out, creating openings for utility lines
2. Indoor Hiding Spots to Check First
Inside, spiders venture directly into undisturbed and low-traffic areas:
- Basement corners and window wells
- Crawl spaces under the home
- Garage ceiling corners and shelving
- Utility and laundry rooms
- Backside of water heaters or HVAC equipment
What Longview Homeowners Can Do Before Calling a Pro
- Seal foundation gaps – Apply weatherproof caulk to any cracks where soil has pulled away from your home’s base.
- Run a dehumidifier in your basement – Keeping indoor moisture under control makes your home less attractive to moisture-seeking spiders.
- Replace dried-out weatherstripping – Hot summers wear it down faster; inspect every season.
- Clear outdoor clutter near the foundation – Firewood stacks, plant pots, and debris can combine to create harborages right at your entry points.
- Check and repair window screens – Tears as small as a pinhole quickly widen in the heat, giving spiders easy access.
- Vacuum regularly in low-traffic areas – Dispose of existing webs and egg sacs before populations explode.
When DIY Is Not Sufficient Especially With Venomous Species
Western Black Widows are already common in Adams County, and the dry years have them coming inside more often. “In Colorado, venomous spiders are more likely to interact with homes after periods of significantly below average rainfall,” a Colorado State University Extension study found. That is a risk not worth underestimating.”
Commercial sprays may eliminate a few spiders, but they seldom penetrate the harborage areas where spiders live and breed. Local providers such as Pointe Pest Control know that Longview’s seasonal changes dictate spider behavior and can implement targeted solutions that address the root cause, not just what residents can see.
If spiders are a problem in Longview, knowing when to seek professional help makes all the difference, especially if venomous varieties are involved.
