Cellar spiders can be controlled by reducing moisture, sealing entry points, and using sticky traps or insecticides safely.
Understanding Cellar Spiders: Why They Invade Your Home
Cellar spiders, often called “daddy long-legs,” are common household arachnids that thrive in dark, damp environments. They prefer basements, crawl spaces, and other low-light areas where moisture levels are high. These spiders spin messy, irregular webs to catch smaller insects and thrive quietly out of sight. While they’re generally harmless to humans and even beneficial by controlling pests, their webs and presence can be unsettling.
Their long legs and small bodies make them easy to spot once you know what to look for. However, their ability to hide in cracks and corners means infestations can grow unnoticed until webs become widespread. Understanding their behavior is the first step toward effective control.
Why Cellar Spiders Are Hard to Eliminate
Cellar spiders are resilient survivors. Their webs are sticky but fragile, allowing them to quickly rebuild after disturbances. They reproduce rapidly with females laying multiple egg sacs throughout the year. Their diet of other insects means they often stick around as long as there is a food source.
Another challenge is their attraction to moisture. Basements or cellars with poor ventilation provide the perfect habitat for these spiders. Even if you remove visible spiders and webs, underlying issues like humidity or cracks in foundations will invite new ones.
Their ability to move through tiny gaps also makes physical barriers tricky without thorough sealing. This combination of factors means a multi-pronged approach is necessary for lasting results.
Effective Methods For How To Get Rid Of Cellar Spider
1. Reduce Moisture Levels
Moisture control is crucial in any cellar spider strategy. These spiders favor damp environments because they attract the insects they prey on. Using a dehumidifier or improving ventilation can dry out basements and crawl spaces significantly.
Check for leaks in plumbing or walls that might increase humidity. Fixing these will not only deter cellar spiders but also prevent mold growth and structural damage over time.
2. Seal Entry Points
Spiders enter homes through tiny cracks in foundations, gaps around pipes, windows, doors, and vents. Inspect your basement or cellar thoroughly and seal any openings with caulk or weatherstripping.
Even small holes near utility lines can act as highways for cellar spiders moving inside from outdoors. Pay special attention to areas where wiring or plumbing enters your home.
3. Remove Webs Regularly
Physically removing spider webs disrupts their hunting grounds and discourages them from settling in one spot long-term. Use a broom or vacuum cleaner attachment to clear webs from corners, ceilings, windowsills, and other surfaces weekly.
This simple action reduces the number of hiding spots available while making your space less inviting overall.
4. Use Sticky Traps
Sticky traps are an effective non-toxic way to catch cellar spiders without spraying chemicals indoors constantly. Place adhesive traps along walls where you notice spider activity or near light sources that attract insects (their prey).
Check traps regularly and replace them when full of trapped bugs or dust buildup occurs.
5. Apply Insecticides Carefully
If infestations persist despite non-chemical measures, targeted insecticide use may be necessary. Choose products labeled specifically for spiders or crawling insects.
Apply sprays around baseboards, window frames, door thresholds, and other entry points rather than indiscriminately over large areas inside your home to minimize exposure risks.
Wear gloves during application and ventilate rooms well afterward.
The Role Of Natural Remedies In Spider Control
Many homeowners prefer natural remedies over chemical insecticides due to safety concerns around pets and children. Some natural deterrents have shown promise against cellar spiders:
- Essential Oils: Peppermint oil stands out as an effective repellent due to its strong scent irritating to spiders.
- Vinegar Solutions: A mixture of white vinegar and water sprayed on webs can discourage rebuilding efforts.
- Citrus Peels: Placing lemon or orange peels near entry points may help repel these eight-legged intruders.
While these methods rarely eliminate entire populations alone, they complement other control techniques well when used consistently.
Seasonal Considerations For Cellar Spider Control
Temperature shifts influence cellar spider activity patterns significantly:
- Fall: Spiders seek warm indoor spaces; sealing cracks before cold weather hits helps prevent influxes.
- Winter: Populations slow down but don’t disappear; ongoing moisture control remains essential.
- Spring/Summer: Increased insect populations outdoors mean more food indoors if doors/windows aren’t screened well.
Adjusting your prevention tactics seasonally improves overall success rates dramatically.
The Science Behind Why Cellar Spiders Are Harmless But Annoying
Despite their creepy appearance with gangly legs spanning inches across tiny bodies, cellar spiders pose no real threat to humans:
- No Venom Danger: Their venom is weak enough that it doesn’t affect people beyond minor localized irritation if bitten (which is rare).
- Pest Control Allies: By feeding on flies, mosquitoes, moths—cellar spiders reduce populations of nuisance insects naturally.
- No Disease Transmission: Unlike some insects like ticks or fleas that spread illnesses—cellar spiders carry no pathogens harmful to humans.
Understanding this helps reduce fear while motivating homeowners toward humane yet effective management rather than eradication attempts fueled by panic.
A Practical Comparison Table: Control Methods For Cellar Spiders
| Method | Efficacy Level | Main Advantages & Disadvantages |
|---|---|---|
| Moisture Reduction (Dehumidifiers/Ventilation) | High | Keeps environment hostile; also prevents mold but requires investment & maintenance. |
| Sealing Entry Points (Caulking/Weatherstripping) | High | A permanent barrier; labor-intensive but stops new arrivals effectively. |
| Web Removal (Vacuuming/Brooms) | Medium-High | No chemicals involved; needs frequent repetition; disrupts spider habitats temporarily. |
| Sticky Traps Placement | Medium | Catches existing spiders; non-toxic but doesn’t prevent new ones from entering. |
