Introduction
If you have spotted spider eggs in your house, you might be wondering: “How long do spider eggs take to hatch?”
The short answer is that most spider eggs hatch within 14 to 21 days, depending on the species, temperature, and environmental conditions. However, some species can take months to hatch, especially in colder temperatures.
While spiders help control other pests, an infestation of spider eggs inside your home can quickly lead to unwanted arachnids. If you are concerned about spider eggs hatching in your home, keep reading to learn how to identify, remove, and prevent them before they become a bigger problem.

How Long Does It Take for Spider Eggs to Hatch?
The hatching time for spider eggs depends on the species and environmental factors.
- Most spider eggs hatch within 14 to 21 days (2 to 3 weeks)
- Some species, such as wolf spiders, can hatch in 10 days
- Others, like the brown recluse spider, can take up to 30 days
- In colder temperatures, spiders may delay hatching for several months
Once the eggs hatch, baby spiders (spiderlings) stay close to their nest for a few weeks before dispersing. Some species, such as wolf spiders, carry their young on their back until they are mature enough to survive on their own.

What Do Spider Egg Sacs Look Like?
Spider eggs are typically wrapped in silk sacs, which protect them from predators and environmental factors.
Common Characteristics of Spider Egg Sacs
- Shape: Round or oval, resembling a small cotton ball
- Color: White, brown, or tan
- Texture: Silky and soft to the touch
- Size: Ranges from the size of a pinhead to a quarter
- Location: Found in dark, undisturbed places like basements, attics, under furniture, or corners of ceilings
A single spider egg sac can contain anywhere from 150 to 300 eggs, depending on the species. Some species, such as the black widow, can lay up to 1,000 eggs per sac.

How to Prevent Spider Eggs in Your Home
The best way to prevent spider eggs is to eliminate spiders before they lay eggs.
Top Prevention Methods
- Seal Entry Points: Block cracks in walls, gaps in windows, and crevices around doors
- Declutter Your Home: Spiders love hiding in piles of clutter, stored boxes, and unused furniture
- Vacuum Regularly: Cleaning removes webs, eggs, and food sources that attract spiders
- Use Essential Oils: Spiders dislike peppermint oil, tea tree oil, and vinegar sprays
- Turn Off Exterior Lights at Night: Lights attract insects, which in turn attract spiders
- Control Other Pests: Spiders feed on flies, mosquitoes, and ants—eliminate their food source to keep them away
If DIY prevention is not enough, Vinx Pest Control offers professional spider treatments to eliminate infestations and prevent future problems.
How to Get Rid of Spider Eggs Before They Hatch
If you have already found spider eggs in your home, it is important to remove them before they hatch.
Effective Spider Egg Removal Methods
- Vacuum the Egg Sacs: Use a vacuum cleaner with a hose attachment to remove egg sacs and webs
- Dispose of Eggs Immediately: Place vacuum contents in a sealed plastic bag and throw it away outside
- Use Insecticide Sprays: Apply spider-specific insecticides to cracks, corners, and web-heavy areas
- Try Natural Remedies: Use diatomaceous earth or a vinegar-water spray to kill spider eggs naturally
- Call a Professional Exterminator: If you have multiple spider egg sacs or recurring infestations, schedule a pest control service for a permanent solution
Do Spiderlings Stay in the House After Hatching?
After hatching, baby spiders stay near their nest for a few weeks before dispersing. Some species release their young immediately, while others carry them for protection.
Unfortunately, if spiders hatch inside your home, they may hide in corners, furniture, and vents, leading to a growing infestation.
When to Call a Professional Pest Control Service
- You have found multiple spider egg sacs
- Spider webs are appearing all over your home
- You keep seeing baby spiders, even after cleaning
- You have venomous spiders like black widows or brown recluses
