How Fast Do Spiders Reproduce

If you notice a few spiders in your home, the problem might worsen if you don’t rectify it immediately. Spiders reproduce quickly because they can lay thousands of eggs at any time. So, if you have a spider problem in your home, you’ll want to take the proper measures to get rid of these spiders before they reproduce.

Please continue reading to learn more about how fast spiders reproduce so that you can prevent an infestation. We will discuss how many eggs spiders lay, how long it takes for the eggs to hatch, and the types of spiders you need to consider when it comes to reproduction.

How Many Eggs Does a Spider Lay?

During the lifespan of a female spider, it will produce over 4000 eggs. However, these egg sacs are not laid all at once. The average amount of eggs you’ll see in a single sack is 250 for a common house spider. This situation means your spider problem can quickly spiral out of control if you have a female laying eggs in your home.

Spider Egg Hatching Duration

Fortunately, compared to other pests in your home, it can take longer for spider eggs to hatch, which means you have more time to get rid of them. Household spiders usually take up to three weeks for eggs to hatch, and the baby spiders will hang out close to the nest for weeks after they hatch until they’re big enough to venture further.

However, if it takes you a while to notice your spider problem, you might not have as much time to take care of spider eggs as you think. It would be best to contact a professional for egg removal as soon as you notice a problem.

Some Spiders Mate More Than Others

Some spider species only mate once, while others mate several times throughout their life. For example, mygalomorph spiders frequently reproduce because they shed their skin several times a year. These fighters can live to be 25 years old, which is why people know them for their longer lifespans.

However, your average household spider will typically only live for a year and reproduce a couple of times. Some spider species only reproduce once during their entire lives. For eggs to happen, you’ll need to have male and female spiders in your home. Female spiders cannot reproduce asexually.

Do All The Eggs Make It?

Even though spiders usually lay over 200 eggs, not all of these eggs will develop into adult spiders. If you keep your household cold, most of these eggs won’t even hatch because they need a warm environment to survive. That’s why you may notice dead eggs that didn’t live through the winter at the beginning of spring.

After the spider eggs hatch, most spiders will die shortly after leaving the egg sac. Only a few of the 200 spiders hatched from the eggs will survive into adulthood. If spider eggs encounter a dangerous situation before they hatch, they are unlikely to survive. These eggs are extremely vulnerable to the climate around them.

Female spiders protect their eggs by either creating a silk sack around them or staying with the eggs until they hatch. Spider eggs are not durable, so female spiders are unlikely to abandon their eggs after fertilization.

Final Thoughts

Spiders can reproduce quickly because they lay multiple eggs simultaneously, even though not all survive. However, other household pests reproduce quicker than spiders because spiders take up to three weeks for their eggs to hatch. If you notice many spiders in your home, you’ll want to contact a professional for removal because the more spiders you have, the more they’ll reproduce.
