Spiders are pretty common in most homes. However, for many people, their sight can dredge up the fear of creepy crawlers and arachnophobia. Spiders are usually attracted to bugs, which make up the majority of their diet.
Having a few spiders in your home is actually a good thing. They prey on other pests and control their infestation rates.
The female spider enters your home with an egg sac that can contain around 100 eggs. When these eggs hatch, baby spiders will emerge and begin to spread out across your house. These spiderlings are cannibalistic by nature and need to leave the egg sac, so they don’t eat one another.

Where are these spiders coming from?
1. Spiders are attracted to light
One of the primary reasons that spiders may be drawn to your home is that they are attracted to light. Spiders are nocturnal creatures that prefer to hunt at night, and your home provides a perfect light source. If you have a lot of spiders in your home, you may want to consider keeping your lights off or dimming them at night.
2. Spiders are looking for food
Another reason that spiders may be entering your home is that they are looking for food. Spiders are predators that typically eat insects, and your home is likely full of potential prey for them. If you have a spider problem, it may be due to an infestation of other pests in your home.
3. Spiders are seeking shelter
Spiders may also be entering your home in search of shelter. Your home provides a warm, dry environment that is ideal for spiders to build their webs and raise their young. If you have spiders in your home, it is important to seal any cracks or openings that they may be used to get inside.
4. Spiders follow pheromones
Another possibility is that the spiders in your home are following pheromones left behind by other spiders. When a spider enters a new environment, it leaves behind a trail of pheromones that can attract other spiders to the area. If you have a spider problem, it may be due to pheromones left behind by other spiders that have already entered your home.
5. You have brought them in yourself
Finally, it is possible that you have inadvertently brought spiders into your home yourself. If you live in an area with a lot of spiders, it is possible that some have hitchhiked their way into your home on clothing or shoes.
6. Spider eggs
The female spider lays her eggs and produces a silken sac to protect them. Usually, each sac contains 100 eggs. The sac may be attached to a surface, hidden in the web, or carried by the female. If you see signs of the sacs indoors, it means that more spiders are coming soon. When the eggs hatch, hundreds of baby spiders can emerge from the egg sac and crawl all over your walls and into tiny spaces throughout your home. Since these spiders are cannibalistic by nature, they will try to spread out so that they don’t eat each other. As a result, spiderlings might end up all over your house.
What are the most common spider species found in homes?
There are several species of spiders that are found in homes. Some may be harmful to humans and even poisonous. However, a majority of common spiders are harmless. Here is a list of both harmful and harmless spiders that are commonly found in our homes.

General places where spiders use as hiding spots in the house
Spiders prefer different hiding spots within the house. Some are attracted to moisture and dump places, while others prefer drier environments.
- Plant materials such as flowers or herbs found in the house are a major attraction to spiders. These plants provide a natural setting for them to form webs, and also, plants attract insects which are the main food source for spiders.
- Dark and obscure places are another site for spiders to hide. The spiders may be found under furniture and closets around the house. Also, household objects such as carpets and mats can be good hiding spots for spiders.
- Messy environments such as clutter of books, magazines, and kitchen utensils provide good hiding spots for spiders. They prefer untouched areas such as these to form webs and lay eggs.
- Wolf spiders prefer to hide in cracks and holes found around the house. They are mainly attracted to these spots because they do not form webs.
- The most common place to spot a spider in the home is on the corners of the ceiling in the house. These spots may not be a hiding area, but they are good breeding sites and also provide a perfect ambushing area since most flies are found in these places.
- Threatening spiders like the black widow and hobo spider tend to hide underwood and rock materials such as plant pots in the house. They require such an environment for them to lay numerous eggs and also to set their webs.
- The garage is the most likely area to find a spider infestation. This area provides the best environment since it contains clutters of materials that spiders use for nesting and breeding. The spiders enter the garage through holes, cracks, and the main entrance door.
