Understanding The Threat of Spider Eggs In Your Home

Did you know that a single female spider can produce 3,760 eggs in her lifetime? Now imagine the many little spiders you have ignored in your house, thinking they are tiny and won’t cause harm. Recent statistics show that about 200 million spiders invade homes across the US.

Oregon is home to 500 different species of spiders. Homeowners often face challenges due to the high reproductive rates of these pests. It has become more important than ever to understand and manage spider egg infestations with effective Saela Pest Control.

Read this blog to learn about the lifecycle of a spider, how to identify spider eggs, and the health risks associated with such infestations.

The life cycle of a spider

While there are different species of spiders, with each having a different timeframe in their life cycle, they all have the same stages: egg, spiderling, juvenile, and adult.

Egg stage

The life of a spider begins with the egg stage. During this stage, the mother spider wraps the eggs in a silk egg sac. This egg sac can contain any number of eggs, depending on the species. For example, the Giant House Spider commonly found in Oregon can lay several thousand eggs at a time.

Spiderling stage

When the eggs hatch, the little spiders that come out of it are known as spiderlings. They look like regular spiders but are only tiny in size. Hatching occurs two to three weeks after the female spider lays the eggs.

Juvenile and adult

After the hatching, once the eggs become spiderlings, they go through rapid development. The tiny spiders shed their exoskeletons multiple times before reaching the juvenile stage and then, finally, the adult stage. Sometimes, it can take months or years for a spider to grow into an adult.

Identifying spider eggs

Learning to identify spider eggs in the house is very important to avoid an infestation. They might differ in appearance and where they are found depending on their species.

This table might help you identify spider eggs more easily:

Criteria	Features
Size	Ranging from 1mm to a few millimeters in diameter.
Shape	Usually spherical or oval.
Color	Commonly white, cream, yellow, or light brown. Some species may have eggs with a translucent appearance.
Egg Sac	Often found in a silken sac, which can be round, oval, or irregularly shaped. The sac can be white, brown, or gray.
Location	Indoor locations may include corners of rooms, attics, or basements.

Common locations

Whether it be spiders or ants, you will most likely find pests hiding in the dark and undisturbed corners of your house. These locations may include the following:

Corners of rooms and ceilings
Behind furniture and appliances
In attics and basements
Underneath eaves or decks
Between window frames and walls

Female spiders specifically choose these places to lay their eggs to protect them from predators and shelter their little ones. The Giant House Spider of Oregon creates a large and round sac.

Risks and concerns

Most spiders that you will find in your house are not harmful to humans, nor are their eggs or egg sacs. However, the presence of thousands of spiders in the house is also not favorable.

Some spider species, such as the black widow and brown recluse, can bite and cause discomfort. The presence of spider egg sacs can also trigger allergies and phobias. Not to mention, spiders can create webs all over your house and ruin its appearance.

Many people experience psychological discomfort at the mere sight of a spider. Data indicates that about 3% to 15% of the population in Oregon have arachnophobia or an intense fear of spiders. Therefore, having spiders in the house can significantly deteriorate one’s quality of life.
