Remove Joro Spider Eggs
If you’ve started noticing large, colorful spiders around your home, you may already be familiar with the Joro spider. While adult Joro spiders often grab attention because of their size and bright markings, the real concern for homeowners usually starts when egg sacs appear.
Understanding how to identify and remove Joro spider eggs — and when to call a professional — can help prevent a small issue from turning into a seasonal invasion.
What are Joro spider eggs?
Joro spider eggs are laid inside protective sacs, typically in late summer or fall. Each sac can contain hundreds of eggs, which overwinter and hatch in spring. While not aggressive or dangerous, Joro spiders can multiply quickly if egg sacs are left undisturbed.
Egg sacs are usually:
- Tan, light brown, or gray
- Papery or slightly fuzzy in texture
- About the size of a quarter to a half dollar
They’re often attached to outdoor structures where spiders feel protected.
Common places Joro spider egg sacs are found
Homeowners are most likely to find Joro spider eggs in quiet, undisturbed areas around the exterior of the home.
Typical locations include:
- Under eaves and roof overhangs
- On siding or brick near corners
- In sheds, garages, and carports
- On fences, outdoor furniture, or railings
- Near shrubs or tall vegetation close to the house
Because these areas aren’t checked often, egg sacs can go unnoticed until spiders begin appearing months later.
Why removing egg sacs matters
One of the biggest misconceptions about spiders is that removing adult spiders alone solves the problem. With Joro spiders, egg sacs are the real source of recurring activity.
Leaving egg sacs in place can result in:
- Dozens or hundreds of spiderlings emerging in spring
- Increased webbing around the home
- Repeated seasonal infestations
Early removal is one of the most effective ways to reduce future spider activity without relying on heavy treatments.
Can homeowners remove Joro spider eggs themselves?
In some cases, yes — but it needs to be done carefully.
If egg sacs are easily accessible and limited in number, homeowners can take basic steps to remove them safely. However, improper handling can spread eggs rather than eliminate them.
How to safely remove Joro spider eggs
If you plan to remove egg sacs yourself, follow these best practices:
Wear protective gloves
Always wear gloves to avoid direct contact. While Joro spiders are not aggressive, gloves provide protection and peace of mind.
Use a sealed removal method
Do not crush egg sacs or knock them onto the ground. Instead:
- Use a tool or scraper to gently remove the sac
- Place it directly into a sealed plastic bag
- Dispose of the bag in an outdoor trash bin
This prevents eggs from dispersing into the environment.
Avoid vacuuming egg sacs indoors
Vacuuming can sometimes spread eggs if the vacuum is not properly sealed or emptied immediately. If used, the vacuum contents should be removed and discarded outside right away.
What not to do when removing spider eggs
Some common mistakes can make the problem worse:
- Spraying egg sacs with household insecticides: Most sprays do not penetrate the protective casing
- Leaving removed sacs on the ground: Eggs may still hatch
- Ignoring hidden areas: Missing sacs can restart the cycle
Effective removal is about thoroughness, not force.
When professional removal is the better option
If you’re seeing multiple egg sacs, heavy webbing, or recurring spider activity year after year, professional help is usually the smarter choice.
Professional pest control can:
- Locate hidden or hard-to-reach egg sacs
- Safely remove and dispose of them
- Treat areas to discourage reattachment
- Reduce spider-friendly conditions around the home
This is especially helpful for multi-story homes, dense landscaping, or homes near wooded areas.
Preventing future Joro spider egg sacs
Once egg sacs are removed, prevention becomes the next priority. Simple changes around the home can significantly reduce spider activity.
Helpful prevention steps include:
- Reducing exterior lighting that attracts insects
- Trimming vegetation away from siding and rooflines
- Sealing gaps, cracks, and crevices
- Keeping sheds and garages clean and organized
- Scheduling routine exterior inspections
Spiders follow food sources. Fewer insects usually means fewer spiders.
