What Time Of Year Do Spiders Lay Eggs?

I have always wondered about this even before I became a pest exterminator.

What time of year do spiders lay their eggs? The brief answer is that spiders multiply all year. Even though they will appear less active in the winter and fall they will still mate, lay eggs, and feed.

Where Do Spiders Lay Eggs?

Spiders won’t usually lay their egg sac in a easy to reach place. They normally find a place that is protected from the elements and predators.

Many species of spider will protect the sac with many layers of silk, followed by a web. Spiders will also stay around and guard the egg sac as to protect their little spiderlings from harm.

Some spiders carry their spiderlings on their back until they are big enough to go out on their own.

How Many Eggs Do Spiders Lay?

The female spider will typically lay between 15-20 egg sacs during their lifetime. There is usually about 150-200 eggs in each egg sac. This is a general answer for most species of spider. as some spiders don’t use an egg sac.

Where Do Spiders Go When They Hatch?

The young nymph spiders will when they are ready leave the egg sack and venture out into the great unknown.The exception to this is in the colder months the immature spiders will stay in the sac and wait it out until spring. Spiderlings will cast their parachute silk string and drift away they don’t travel very far from there point of origin. They will the immature spiders will stay in the sac longer during the colder months.The young spiderlings will be seeking out the light, but when they get older they will prefer the darkness.

Lots of the spiderlings will be devoured by predators, such as the praying mantis, and blue lizards etc. Although only a small percentage of them will survive to adulthood, the population will increase if left unchecked.

Where Do I Find Spiders In And Around My Home?

While very hardy and versatile creatures, spiders do have certain places that they like to seek out in order to lay their egg sacs. They like to find somewhere without too much moisture, noise or light. Wood piles, under rocks, and compost provide a perfect location for them to lay their eggs.

If you ever look at your bushes and trees just outside your home, it is easy to find spiders webbing all throughout those areas. Alway make sure to cut back foliage and vegetation from directly touching your home as to avoid unwanted infestations.

Other places that spiders prefer are:

Crawl spaces/Basements

Window fixtures

Sheds, and other dry outdoor places

Attics

Inside cracks in the walls

Under your Furniture

There are ways to deter spiders from laying eggs on your property. You can use a cobweb duster to brush the inside and outside of your home, or any other affected areas. Downspouts, window sills, eaves and soffits, doorways, as well as some of the other places previously mentioned, are the areas you want to target.

What are Some Tips For Dealing with Spiders?

If you decide to work out in the garden make sure to wear gloves as to avoid an unwanted bite. Even though not all spiders are poisonous you will still feel discomfort or itchiness from a spider bite.

Fall is the prime time for pest infestations. As food supplies diminish due to cooler weather, and many of the bugs set about their searches for safe places to wait out the winter. Arachnids (spiders) during this time of year begin to make more public appearances.

Many of the nation’s arachnid species are harmless, although certain exceptions could be moving into your home as we speak.
