How to Get Rid Of Spider Eggs

This page is an expert guide on getting rid of spider eggs using the products and methods suggested by our experienced pest control specialists. Follow this guide and use the recommended products and we guarantee you will be successful in eliminating spider eggs from your home.

One moment you may be relaxing in your living room until you casually look up and find two brown sacs hanging from the ceiling, almost mocking you. Anything else wouldn’t be so scary, but these browns sacs are not just anything—they are spider eggs. If you bump or in some way mishandle them, the sac may start raining spiders on you and that won't be pleasant.

Spiders stray into the home from time to time which is a minor issue but it can become a big problem when they begin laying spider eggs. Depending on the species of spider (black widow, brown recluse, etc.), the number of spider eggs in a spider egg sac can range from a small number to more than 150 to 300 eggs. For this reason, it is important to take measures to remove spider eggs from your home before they hatch and you have an infestation of spiders on your hands.

If you are concerned about spider eggs you're finding on your property, we know just what you need in the form of professional products that will safely and quickly remove spider eggs from your home.

Before you can plan a treatment approach, you need to know for sure if you are dealing with spider eggs via identification. If you're wondering what do spider eggs look like, below are some unique traits to keep in mind to help you properly identify spider eggs.

  • Spider eggs are very small in size, so much so that they can be difficult to see by the naked eye. However, when they are bunched together they can be easier to spot. Mostly because the spider eggs usually are in an egg sac put together by an adult female spider.
  • Spider egg sacs range in color from light and dark brown to light and dark gray. Sometimes they are even cream-white in color. The sacs around the eggs are composed of the web spun by the mother. It is spun so often, they appear dark and opaque and very round.
  • When these spider eggs hatch, they unleash dozens and dozens of small spiderlings. These newly born spiders are pale and move frighteningly fast. Coming back to the sac, some of them are protected by a very protective mother, while others are just left to their own devices.
  • These spiderlings grow and molt until they reach an age of sexual maturity and seek the opposite gender to lay more eggs. This means, if we don’t get rid of the spider eggs in our house, then we are encouraging them to infest.

Use the image and description above to help you in identifying spider eggs and spider sacs. If you are not totally sure, contact us and we will try to help you with identification.



Once you are sure you are dealing with spider eggs, carry out an inspection to determine where they are being found and how severe of a problem it is. Inspecting for spider eggs can be hard to do since they are so small but there are prime areas where they can be discovered and treated.

Where To Inspect

Depending on the spider species, the spider egg sac can be found in different areas. Some can be found on the underside of leaves in your yard, attached to tree branches outdoors, in a burrow, or on the eave of your home. Indoors, they may be found in areas that are secluded or are not visited often like the attic, garage, or basement.

What to Look For

You want to look for spider webs that have small egg sacs that are cream-colored and are round or oblong-shaped.


Once you have located spider eggs sacs and webs, you can move forward with treatment. Often, using home remedies may not be enough to get rid of spider eggs. That's when it would be useful to turn to products that the pros use. We suggest using a duster to wipe away and destroy spider webs and spider eggs as well as spraying a product called Web Out.

Step 1: The Spider Cobb-Web Head Duster and Pole Technique

If the spider egg sac is in a hard to reach area, you can clear out the egg sac as well as any additional cobwebs using a duster head such as the Cobb Webb Duster Head.

The Cobb Webb Duster head has special small nylon bristles on its head which is perfectly designed to remove cobb webs and spider eggs. Are the spider eggs still too far to reach with the duster head? The Webb duster head has a threaded end which can be used to attach an extension pole.

Use the Cobb Webb Duster head to wipe directly at the area where the spider egg sacs are found such as high riders, ceiling corners and similar areas. Once collected you can simply rub the duster around on some grass to clean the spider eggs off.

Step 2: Spray The Spider Eggs Away with Web Out

Spraying Spider Eggs

For a more permanent solution to getting rid of the spider egg sac and the potential hundreds of unborn spiders inside, you could use an insecticide as a spider spray to eliminate the spider eggs. We recommend using Web Out which is a spider spray that you can apply directly to the spider egg sac or spider web and its formula will break down the spider eggs and materials and kill spiders quickly.

To apply, first shake the product well. If you bought the 32 oz. ready-to-use spray bottle, the application is easy. Just spray and shoot where spiders are found or in places where you have found spider webs and spider eggs. One quart should cover about 200 to 300 square feet.

Spiders and their eggs and egg sac that come into contact with the product should die out in just a few minutes. After that, just sweep and wipe away the spider remnants with the Cobb Webb and discard. 

Step 3: Spray Supreme IT

For a more long term solution to control spiders and their eggs, we recommend spraying Supreme IT insecticide. This is our patented insecticide concentrate that controls a wide array of household pests, including spiders. The best thing about it is that an application can remain effective between 30 to 90 days. 

Simply mix the appropriate labeled amount of Supreme IT in a tank sprayer with water and spray directly to where you have found the spider eggs and webbing. A typical spot treatment will be 1 to 2 oz per gallon of water to treat 1,000 sq. ft. Spray along the eaves of your home, corners, along doors and windows and points of entry.

Once you have eliminated spiders and their spider eggs from your home, you need to make sure they don't reinfest. If you don’t wish to deal with spider eggs in the first place then take the following preventive measures:

  • Remove all the firewood and logs from your home. Keep your yard clean and remove dried leaves and organic debris from the grass. Furthermore, keep your yard maintained ad trim overgrown foliage regularly.
  • Reduce clutter from the house by removing extra piles of old papers, newspapers, cardboard boxes, bags etc.
  • Make sure the cracks in the basement and foundation are sealed with caulk.
  • If your house is often victimized by spiders then replace the standard lights with high-pressure sodium vapor or halogen lights. Lights attracts insects at night, as long as it is safe, keep the lights turned off at night or have them installed farther away from the door in a way that they illuminate the door and porches area.
  • Spray a preventative treatment of Supreme IT around the perimeter of the house to discourage spiders from the area and in places you have seen the spider egg sacs.
