Misunderstood Predators That Don’t Belong Indoors
Spiders play an important ecological role by feeding on other pests—but that doesn’t mean they belong in your home or business. While most spiders are harmless, their presence in large numbers—or the appearance of venomous species like the black widow or brown recluse—can create anxiety, unsanitary conditions, and real safety concerns. At Blackwood Pest Solutions, our spider control program is designed to bring peace of mind. Through proper species identification, safe and effective treatments, and preventative strategies, we help keep your environment clean, comfortable, and spider-free.
Common Spiders Found Indoors
Most spiders are not dangerous, but their webs, egg sacs, and sudden appearances can still be unsettling. Here are a few common species that may be found in and around your property:
- House Spiders
Small, web-spinning spiders commonly found in corners, ceiling joints, and closets. Harmless and helpful in controlling insect populations. - Wolf Spiders
Large, fast-moving spiders that hunt rather than build webs. Often mistaken for more dangerous species, but generally harmless to humans. - Cellar Spiders (Daddy Longlegs)
Long-legged spiders found in garages, basements, and crawl spaces. Not dangerous, but known for creating excessive, unsightly webs. - Black Widow
Identified by the red hourglass marking on the underside of its abdomen. Its bite is venomous and can cause severe reactions. Requires professional removal. - Brown Recluse
Tan, with a violin-shaped marking on its back. Known for its necrotic bite and reclusive behavior. Found in undisturbed spaces like storage boxes, closets, or basements.
Signs of a Spider Infestation
- Frequent sightings of spiders indoors, especially in dark or quiet areas
- Cobwebs in corners, under furniture, or along ceiling lines
- Egg sacs on walls, ceilings, or inside storage containers
- A rise in other pest activity (spiders follow food sources)
Spiders are often drawn inside while pursuing insects—so their presence may signal a larger underlying pest issue.
Are Spiders Dangerous?
Most spiders are not aggressive and would rather avoid human contact. However, the black widow and brown recluse can be hazardous—especially to children, the elderly, or individuals with health issues. Additionally, webbing, egg sacs, and dead insects can make properties appear neglected and impact comfort, cleanliness, and value.
Spider Prevention Tips
- Seal cracks and gaps around doors, windows, vents, and the foundation
- Reduce indoor clutter and vacuum regularly, especially in corners and behind furniture
- Keep storage areas clean, dry, and well-organized
- Use yellow-toned outdoor lighting to reduce insect activity (spiders’ food source)
- Eliminate other insects that may attract spiders
Our Spider Control Approach
At Blackwood Pest Solutions, our spider control process focuses on identifying the species, eliminating their hiding spots, and removing the insects that attract them. Our licensed technicians start with a thorough inspection of your home or business—checking corners, basements, garages, attics, and crawl spaces. We apply EPA-registered, family-safe treatments to high-activity areas, along with physical removal of webs and egg sacs. If venomous species like black widows or brown recluses are found, we implement a more intensive treatment protocol for safe elimination. We also provide prevention tips and sealing recommendations to keep spiders—and their prey—out for good.
