Where Do Spiders Lay Their Eggs?

Spiders are known for their diverse nesting habits. They can often be seen in dark and humid areas. Common locations where spiders may lay their eggs include walls and corners of rooms, underneath furniture, in closets, and even within cracks and crevices in walls. Some species prefer outdoor environments, such as garden areas or sheds, laying the eggs in the web, on the leaves or tree branches.

How Long Does It Take Before Spider Eggs Hatch?

Spider eggs typically hatch in 2 to 3 weeks, this varies based on species, temperature, environment, and humidity. In favorable conditions, like warmer temperatures, the spider eggs may have a short incubation period whereby will hatch within a few weeks. Less ideal environments like cooler temperatures may slow down the hatching process, which will take several months for the eggs to hatch.

What Happens When the Eggs Hatch?

Once spiderlings emerge from the egg sac, they usually settle close to the spider nest area for a few weeks before starting their journey into the world. Later the tiny spiders will move in search for their own territory, seeking for shelter and food.

Pro Tip: Look for spider webs and small, round objects that resemble tiny beads or pearls - these may be spider eggs.

How to Get Rid of Spider Eggs in the House

Removing spider eggs from your home is essential for preventing infestations and minimizing the presence of spiders. Some effective strategies for eliminating spider eggs include:

Use a broom or a vacuum cleaner: Use a vacuum cleaner with a hose attachment to carefully suck up any visible egg sacs. Ensure to empty and dispose of the vacuum bag in the outdoor trash bin to prevent spiders from the eggs hatching and escaping inside your building.

Use Natural Repellents: Some natural substances like essential oils (peppermint, lemon, tea tree, cedar, or vinegar) can act as spider repellents. While these may help deter spiders from certain areas, their effectiveness on spider eggs may be limited due to the protective eggsac surrounding them. Apply these repellents around areas where spiders are likely to hide or lay eggs, but keep in mind that they may not provide long-term protection against egg-laying spiders. Additionally, it is advisable to use face mask when using essential oils, as some individuals may be sensitive to strong scents or oils.

Seal Cracks and Openings: Seal any cracks or gaps or openings on walls, windows, or doors to prevent spiders from their potential harbourage spot and entering your buildings.

Frequently Asked Questions

Spider eggs themselves are not harmful to humans. However, if the eggs hatch, the resulting spiderlings may pose a risk, depending on the species.

Spider eggs are often contained within a silk sac and are whitish or creamy in colour, which makes them different from the eggs of other insects. Additionally, spider eggs tend to be round in shape.

If spider eggs have hatched, the sac may appear deflated or torn, and you may notice tiny spiderlings nearby either on the web or in the area where the egg sac was located.

To prevent spiders from laying eggs indoors, it’s essential to keep the house clean from dust, reduce clutter, seal cracks and gaps, and minimize outdoor lighting that attracts insects.

Leaving spider eggs untreated can lead to a growing population of spiders, potentially leading to a larger infestation and spiders invading and building webs in inconvenient areas. Even though most spiders are harmless to humans, some of them may have venomous bites that lead to discomfort, or allergic reactions in humans.
