Spiders can be a nuisance, especially when they start building their webs outside your house. Not only do these webs create an unsightly appearance, but they can also attract other pests and create an environment that is conducive to further infestations. If you’re looking to keep spiders from building outside your house, there are several effective methods you can try. In this article, we will explore the reasons why spiders build outside houses, the types of spiders you might encounter, and most importantly, the strategies you can use to prevent them from taking over your exterior spaces.
Understanding Spider Behavior
Before we dive into the prevention methods, it’s essential to understand why spiders build their webs outside houses in the first place. Spiders are attracted to areas that provide them with food, shelter, and a safe place to lay their eggs. The exterior of a house, with its nooks, crannies, and abundant insect life, can be an ideal location for spiders to set up their webs. Spiders are generally harmless to humans, but their presence can still be a nuisance, especially for those with arachnophobia.
Types of Spiders You Might Encounter
There are many different species of spiders that might build outside your house, depending on your location and the local ecosystem. Some common types of spiders you might encounter include:
House spiders, also known as domestic spiders, are one of the most common types of spiders found in and around houses. They are typically brown or gray in color and have a distinctive rounded abdomen. House spiders are harmless to humans and actually help to keep insect populations under control.
Garden spiders, on the other hand, are larger and more colorful than house spiders. They are often found in gardens and yards, where they build large, intricate webs to catch prey. Garden spiders are also harmless to humans and are an important part of the ecosystem.
Why Spiders Build Webs
Spiders build webs for a variety of reasons, including to catch prey, protect themselves from predators, and provide a safe place to lay their eggs. Webs are made up of intricate patterns of silk threads that are produced by the spider’s spinnerets. Spiders use different types of webs for different purposes, such as orb webs, sheet webs, and tangle webs.
Prevention Methods
Now that we’ve explored the reasons why spiders build outside houses and the types of spiders you might encounter, let’s look at some effective prevention methods. The key to keeping spiders from building outside your house is to make your exterior spaces less appealing to them. Here are some strategies you can try:
Seal All Entry Points
One of the most effective ways to keep spiders from building outside your house is to seal all entry points. This includes cracks and crevices around windows, doors, vents, and other openings. Use caulk or weatherstripping to seal these gaps, and make sure to check your house regularly for any new gaps or cracks.
Keep Your Yard Clean
Keeping your yard clean is another important step in preventing spider infestations. This includes removing debris, such as leaves and branches, and keeping your grass and gardens well-maintained. Regularly mow your lawn and trim back trees and shrubs to reduce the number of hiding places for spiders.
Remove Standing Water
Standing water can attract spiders and other pests, so it’s essential to remove any sources of standing water from your yard. This includes pet water dishes, bird baths, and clogged drains. Check your yard regularly for any areas where water may be collecting and take steps to remove it.
Use Essential Oils
Certain essential oils, such as peppermint, lavender, and tea tree oil, can repel spiders. Mix a few drops of one of these oils with water and spray it around the perimeter of your house to help keep spiders away.
Other Prevention Methods
There are several other prevention methods you can try to keep spiders from building outside your house. These include:
Using a dehumidifier to reduce the humidity around your house, as spiders prefer humid environments.
Planting spider-repelling plants, such as basil or mint, in your garden or yard.
Using a commercial spider repellent, such as a spray or granule, around the perimeter of your house.

What are the common signs of a spider infestation outside my house?
The presence of spiders outside your house can be indicated by several signs. One of the most common signs is the appearance of webs in corners, windows, and door frames. You may also notice an increase in the number of spiders crawling on the walls, gutters, or other exterior surfaces. Additionally, the presence of egg sacs, which are typically white or yellowish in color and contain hundreds of eggs, can be a clear indication of a spider infestation. If you notice any of these signs, it is essential to take action to prevent the infestation from worsening.
Regular inspection of the exterior of your house is crucial to identify the signs of a spider infestation early on. Check the areas around windows, doors, and gutters, as these are common places where spiders like to build their webs. You should also inspect the foundation of your house, as well as any decks or patios, for signs of spider activity. By being proactive and addressing the issue promptly, you can prevent the infestation from spreading and reduce the risk of spiders entering your home. It is also a good idea to seal any cracks or crevices in the exterior walls, as these can provide an entry point for spiders.
How can I keep spiders from building webs on my windows and doors?
To keep spiders from building webs on your windows and doors, there are several steps you can take. One effective way is to seal any gaps or cracks around the frames using caulk or weatherstripping. This will prevent spiders from entering the area and building their webs. You can also try using a combination of water and dish soap to spray the windows and doors, as spiders do not like the taste or smell of soap. Additionally, you can install door sweeps or threshold seals to prevent spiders from entering through the gaps under the doors.
Regular cleaning of the windows and doors is also essential to prevent spider webs from forming. Use a soft brush or a damp cloth to wipe down the surfaces, paying particular attention to the corners and frames. You can also use a mixture of equal parts water and white vinegar to spray the areas, as the acidity of the vinegar can help to repel spiders. By taking these steps, you can effectively keep spiders from building webs on your windows and doors and reduce the risk of them entering your home. It is also a good idea to trim back any nearby vegetation, as spiders often use plants and trees as a bridge to reach your windows and doors.
What types of spiders are most commonly found outside houses?
The types of spiders most commonly found outside houses vary depending on the region and climate. However, some of the most common species include house spiders, wolf spiders, and cellar spiders. House spiders are typically small to medium-sized and have a brown or gray body with long, thin legs. They are often found in corners, windows, and doors, and are known for their messy, irregular webs. Wolf spiders, on the other hand, are larger and more aggressive, with a gray or brown body and long, powerful legs. They are often found in gardens, yards, and other outdoor areas, and are known for their speed and hunting ability.
Cellar spiders, also known as daddy long legs, are recognizable by their long, thin legs and small, rounded body. They are often found in dark, moist areas such as basements, crawl spaces, and exterior walls, and are known for their messy, irregular webs. Regardless of the species, it is essential to take steps to prevent spider infestations outside your house, as they can quickly spread to the interior and cause problems. By sealing entry points, removing clutter and debris, and using natural deterrents such as essential oils or diatomaceous earth, you can effectively keep spiders under control and reduce the risk of infestation.
How can I prevent spiders from entering my house through the gutters and downspouts?
To prevent spiders from entering your house through the gutters and downspouts, it is essential to keep these areas clean and clear of debris. Regularly inspect and clean the gutters, removing any leaves, twigs, or other materials that may have accumulated. You should also consider installing gutter guards, which can help to prevent debris from entering the gutters in the first place. Additionally, make sure that the downspouts are properly attached and secure, as spiders can often enter through loose or damaged downspouts.
By keeping the gutters and downspouts clean and secure, you can reduce the risk of spiders entering your house through these areas. It is also a good idea to trim back any nearby trees or vegetation, as spiders often use branches and leaves as a bridge to reach the gutters and downspouts. You can also use a combination of water and bleach to spray the gutters and downspouts, as the acidity of the bleach can help to repel spiders. By taking these steps, you can effectively prevent spiders from entering your house through the gutters and downspouts and reduce the risk of infestation.
What are some natural ways to repel spiders from my house?
There are several natural ways to repel spiders from your house, including the use of essential oils, herbs, and spices. Certain essential oils such as peppermint, lavender, and tea tree oil are known to repel spiders, and can be used to spray the exterior of your house. You can also plant spider-repelling herbs such as basil, mint, and chamomile in your garden or yard, as these can help to keep spiders away. Additionally, you can use diatomaceous earth, a natural powder made from fossilized algae, to repel and kill spiders.
To use these natural methods effectively, it is essential to apply them consistently and in the right locations. Spray the essential oils around the perimeter of your house, paying particular attention to areas where spiders are most commonly found. You can also sprinkle diatomaceous earth along the foundation of your house, as well as in any areas where spiders are present. By using these natural methods in combination with other preventative measures, such as sealing entry points and removing clutter, you can effectively repel spiders from your house and reduce the risk of infestation.
How often should I inspect the exterior of my house for spider activity?
It is recommended to inspect the exterior of your house for spider activity on a regular basis, ideally every 1-2 months. This will allow you to identify any signs of spider infestation early on and take action to prevent it from spreading. During your inspection, pay particular attention to areas such as windows, doors, gutters, and downspouts, as these are common places where spiders like to build their webs. You should also inspect the foundation of your house, as well as any decks or patios, for signs of spider activity.
By inspecting the exterior of your house regularly, you can stay on top of any spider activity and prevent infestations from occurring. It is also a good idea to keep a record of your inspections, noting any areas where spider activity is present and any actions you take to address the issue. This will help you to track the effectiveness of your preventative measures and make any necessary adjustments. Additionally, consider inspecting the exterior of your house after heavy rainfall or other extreme weather events, as these can often bring spiders out of their hiding places and increase the risk of infestation.
