Eliminate Cellar Spiders: Safe and Effective Solutions

Cellar spiders, those long-legged arachnids often found lurking in dark corners, may not be dangerous, but their presence can be unsettling. Their webs, often messy and extensive, can also be a nuisance. This guide explores safe and effective solutions to eliminate cellar spiders from your home, addressing common concerns and offering practical advice.

Why are Cellar Spiders in My House?

Cellar spiders, also known as daddy longlegs spiders (though not to be confused with harvestmen, which are arachnids but not spiders), seek dark, damp, and undisturbed areas. This is why basements, cellars, and attics are prime real estate for them. They prey on other insects, so a high insect population can attract them. Cracks and gaps in your home's foundation provide easy entry points.

What attracts cellar spiders?

• Other insects: Their primary food source. Controlling other insect populations is crucial for cellar spider control.
• Moisture: Damp areas are ideal for both spiders and their prey.
• Shelter: Dark, undisturbed spaces provide refuge.
• Easy access: Cracks and gaps in your home's exterior allow entry.

How to Get Rid of Cellar Spiders: A Multi-Pronged Approach

Eradicating cellar spiders requires a multi-pronged approach targeting both the spiders and the conditions that attract them. Simply killing individual spiders won't solve the problem long-term.

1. Reduce Insect Prey:

This is the most crucial step. If there's nothing for them to eat, cellar spiders will eventually leave. This involves:

• Cleaning regularly: Remove dust, debris, and food crumbs that attract insects.
• Pest control: Address other insect infestations (ants, flies, etc.) using appropriate methods.
• Seal food properly: Store food in airtight containers to prevent attracting insects.

2. Eliminate Moisture:

• Repair leaks: Fix any plumbing leaks promptly.
• Improve ventilation: Ensure proper ventilation in damp areas like basements and bathrooms.
• Dehumidifier: Use a dehumidifier in particularly damp areas to lower humidity levels.

3. Seal Entry Points:

• Caulk and seal: Seal any cracks or gaps in your home's foundation, walls, and windows using caulk or sealant.
• Screen windows and vents: Install screens on windows and vents to prevent entry.

4. Remove Webs Regularly:

While this doesn't eliminate the spiders, removing their webs discourages them and makes it easier to monitor their activity. A simple broom or vacuum cleaner will suffice.

5. Natural Repellents:

Some natural repellents might deter spiders, though effectiveness varies. These include:

• Citrus scents: Spiders dislike the smell of citrus. Place citrus peels or use citrus-scented cleaning products.
• Peppermint oil: Similar to citrus, peppermint oil's strong scent can be a deterrent. Dilute it with water and spray in affected areas.
• Eucalyptus oil: Another strong-smelling oil that might discourage spiders. Use similarly to peppermint oil.

6. Vacuuming:

A thorough vacuuming of affected areas will remove not only webs but also spiders and their egg sacs.

7. Professional Pest Control (When Necessary):

If the infestation is severe or you're struggling to control it, consider contacting a professional pest control service. They have access to more potent insecticides and can identify the root cause of the problem.

Are Cellar Spiders Dangerous?

Cellar spiders are generally harmless to humans. While they can bite, their venom is considered too weak to cause significant harm. Their bites are usually no more painful than a mosquito bite.

Do cellar spiders bite?

Yes, they can bite, but their bites are rarely felt and pose no serious threat to humans.

Are cellar spiders poisonous?

While technically venomous, their venom is not considered medically significant to humans.

Conclusion: Coexistence or Elimination?

While cellar spiders are generally harmless, their presence can be undesirable. By implementing the strategies outlined above, you can significantly reduce their numbers and create a less hospitable environment for them. Remember, a proactive and multi-faceted approach is key to long-term success in eliminating these eight-legged inhabitants from your home. Focus on removing their food source and making your home less attractive, and you'll find success.
