Brown recluse spiders are a concern due to their venomous bite. Understanding their reproductive cycle, particularly identifying their egg sacs, is important for managing potential encounters around homes. Knowing what these sacs look like and where they are found helps individuals take safety measures.
Identifying Brown Recluse Egg Sacs
Brown recluse egg sacs appear as off-white to tan silk structures. They are generally round or slightly pear-shaped, measuring about 1/4 to 1/2 inch in diameter, comparable to a small marble or cotton ball. Their texture is papery or silken, often fuzzy or irregular, not smooth or shiny.
Unlike other spider species, brown recluse egg sacs do not reveal individual eggs. The eggs are entirely encased within the silk, invisible from the outside. Each sac typically contains 40 to 50 eggs. This appearance helps differentiate them from the more elaborate or distinctively shaped sacs of other common spiders.
Common Locations for Egg Sacs
Brown recluse spider egg sacs are frequently found in dark, undisturbed areas within a home. Common indoor locations include attics, basements, closets, and crawl spaces. They may also be discovered behind rarely moved furniture, inside seldom-used boxes, or within wall voids. Occasionally, egg sacs can be found in rarely used clothing or shoes stored in these secluded spots.
Outside the home, egg sacs are found in similar secluded, dry environments. These include sheds, woodpiles, rock piles, under logs, or within debris near structures. These spiders seek protected locations undisturbed by human activity.
Action Steps Upon Discovery
If a suspected brown recluse egg sac is found, avoid direct contact. Do not handle the egg sac or any spider with bare hands, as this can lead to a bite.
For safe removal, a vacuum cleaner with a hose attachment is an effective method. After vacuuming the sac, immediately dispose of the vacuum bag outdoors in a sealed plastic bag. Alternatively, sticky tape or a lint roller can pick up the sac, which should then be sealed in a plastic bag and discarded outside.
If multiple egg sacs are discovered or a larger infestation is suspected, contact a professional pest control service for proper identification and comprehensive removal. Reducing clutter and sealing cracks in foundations and walls can help deter spiders from establishing themselves.
