Why Do I Suddenly Have Lots of Spiders in My House?

Have you recently noticed an unusual increase in the number of spiders in your house? This can be quite unsettling, especially if you’re not a fan of these eight-legged creatures. You may be asking yourself, “Why do I have spiders in my house?” Understanding the reasons behind this sudden invasion can help you take appropriate measures to control their population and prevent future infestations.

Reasons Why You Have Spiders in Your House

Spiders are common household pests that can be found almost everywhere. However, a sudden influx of these creatures might indicate specific conditions in your home that are attracting them. Here are some reasons why you might suddenly have lots of spiders in your house.

1. Availability of Food

Spiders are predators and their diet mainly consists of other insects. If your home has a high population of insects, it becomes an attractive hunting ground for spiders. They will move into your house to feast on the readily available food supply. Therefore, if you notice an increase in the number of spiders, it could be due to an underlying insect problem.

2. Ideal Living Conditions

Spiders thrive in certain conditions such as dark, cluttered spaces and areas with high humidity levels. Spaces like basements, attics, garages and garden sheds often provide perfect habitats for them to live and breed. If such conditions exist in your home, they could be the reason why you have spiders.

3. Change In Weather

Changes in weather patterns can also lead to a sudden increase in spider populations inside homes. During extreme weather conditions like heavy rains or droughts, spiders seek refuge indoors where temperatures are more stable and food is readily available.

How To Control Spider Infestation

If you find yourself constantly wondering “why do I have spiders in my house?”, then it’s time to take action to control their population and prevent further infestation. Here are some effective ways to manage a spider problem in your home.

1. Regular Cleaning

Regular cleaning is one of the most effective ways to keep spiders at bay. By vacuuming and dusting regularly, you can eliminate their webs and potential hiding places, making your home less inviting for them.

2. Pest Control

If the spider infestation is severe, it might be necessary to seek professional help. Pest control experts can identify the type of spiders in your house and use appropriate methods to eliminate them effectively.

3. Seal Entry Points

To prevent spiders from entering your home, ensure that all potential entry points are sealed. This includes cracks and crevices in walls, gaps around doors and windows, and openings in the roof or foundation.

Preventing Future Spider Infestations

Prevention is always better than cure when it comes to pest control. Here are some tips on how you can prevent future spider infestations in your home.

1. Regular Home Maintenance

Regular maintenance of your home can help keep spiders away. This includes repairing any cracks or holes in walls, sealing gaps around doors and windows, and keeping your yard clean and free from clutter.

2. Limit Outdoor Lighting

Outdoor lights attract insects which in turn attract spiders looking for food. By limiting outdoor lighting or using yellow sodium vapor lights which are less attractive to insects, you can reduce the chances of attracting spiders into your house.

3. Use Natural Repellents

Certain natural substances like vinegar, peppermint oil, and citrus are known to repel spiders. You can use these as natural repellents by spraying them around areas where you often find spiders.


Understanding why you have spiders in your house is the first step towards managing a spider infestation effectively. By addressing the underlying causes such as availability of food, ideal living conditions, and changes in weather patterns, you can control their population and prevent future infestations.

Remember, while spiders can be a nuisance, they also play a vital role in controlling other pests by feeding on them. Therefore, a balanced approach is necessary when dealing with spiders in your home.
