It is totally normal to see a few spiders around your home in Southern Oregon. Oregon’s climate naturally attracts several species that help control other insects. But when they begin appearing more frequently or in larger numbers, this could be an indicator of another pest problem. At A-One Exterminators, we explain to homeowners from Grants Pass, Eugene, Medford, Klamath Falls, and Brookings what normal is and when it’s time to take action.
What’s Considered Normal in Oregon
Most common spiders found inside Oregon homes:
- Common house spider
- Orb weaver
- Cellar spiders or “daddy long-legs”
These and other species enter homes in search of food. Their population increases during late summer and fall because that is their peak mating season. An occasional sighting of a spider, or even a few, does not automatically translate to an infestation.
When Spider Activity Isn’t Normal
Possible signs of a spider infestation can be described as follows:
- Clusters or groups, large numbers appearing all at once
- Webs are multiplying rapidly within the same rooms
- Near vents, basement, and crawl space areas
- The bolder species move in-such as hobo or wolf spiders
- Other insects increase (their main food source)
In most cases, if there is suddenly an increase in spiders, then another pest issue is happening behind the scenes. Insects such as ants, flies, or moisture-loving insects are attracting them inside.
Why Spider Activity Spikes in Southern Oregon
Seasonal change, humidity, and nearby vegetation all play a role in encouraging spiders to move indoors. Homes in Grants Pass, Eugene, and Medford also have older crawl spaces and basements with high insect activity, where we typically find high spider activity. Coastal areas such as Brookings may experience more moisture-driven fall movement of spiders.
How to Reduce Spider Problems
- Seal gaps around doors, windows, and foundations.
- Reduce clutter in basements and garages.
- Vacuum webs regularly.
- Address underlying insect issues.
- Schedule routine pest inspections.
A professional exterminator can identify the true source of the issue and prevent spiders from returning.
