If you suspect a spider infestation, you should consider using bug bombs or chemical repellents. Alternatively, you can place an essential oil mixture around your garage to discourage new pests.

This post will detail some of the most prevalent garage spiders and how to control them. Additionally, if you have a garage infested with spiders, read on to know how to keep spiders out of your shoes and what insect repellents to use.

Common Garage Spiders

Despite the calm nature of most spiders, two species found in the southern and western United States can do considerable damage if disturbed: the black widow and brown recluse. These spiders like to reside in dimly lit areas such as your garage.

However, these are not the only arachnid species that call your garage home.

The following is a guide to assist you in identifying the most common house spiders and the health concerns some present.

Cellar Spiders

Cellar Spiders

Cellar spiders have very long, slender legs and are often mistaken for daddy-long-legs. They typically have a gray, brown, or whitish hue. The long-bodied cellar spiders are one of the most commonly reported species.

These spiders love basement and garage spaces. Apart from their color, you can tell whether you have cellar spiders in your house by the volume of webs scattered everywhere.

While many spider species devour their old webs before creating new ones, cellar spiders do not. They continue to add to it, resulting in massive quantities of webbing that become a pain to remove. A cellar spider’s web is often very tangled, comparable to that of a cobweb spider.

However, apart from the mess they make, these spiders are entirely safe for people. In fact, they help keep down the insect population within your garage.

Black Widow Spiders

Black Widow Spiders

Five of the 31 species of widow spiders are present in residential areas in the United States. The black widow is one of them.

Black widow spiders are about ½ inch (1.27 cm) long and have a glossy black body with red, yellow, or orange patterns on the abdomen. 

Black widow bites might go undetected or have the sensation of a pinprick. It’s worth noting that only the female spider, which has red hourglass markings, poses a hazard to humans.

These bites may cause severe muscular pain, requiring medical treatment. As a result, you’ll need a safe approach to identifying and removing these arachnids as quickly as possible.

Brown Recluse

Brown Recluse

Brown recluse spiders, also known as “fiddle back spiders,” have soft bodies and range from light tan to dark brown. Adult spiders measure approximately ½ inch (1.27 cm) in length and have long, delicate legs covered in short, dark hairs.

These spiders have a pale yellow to reddish-brown carapace with a brown patch connected to the front by brown stripes. In all, these marks resemble a violin.

The presence of three pairs of eyes placed in a semicircle on the forepart of the skull and the typically long legs serve as distinguishing markers.

Most importantly, the brown recluse’s bite is toxic. The complex venom wreaks havoc on the surrounding tissues, causing necrosis and damage. The venom may cause harm to deeper tissues in extreme instances, though significant disease and death are uncommon.

Why Are There So Many Spiders in Garage?

Spiders will establish a home in your garage to meet their fundamental requirements: food and shelter.

There may be so many spiders in your garage if it is infested with mosquitoes and flies since most spiders feed on flying insects. Some arachnids also like the comfort of dampness. Winter’s low temperatures and early summer’s high humidity may leave your garage susceptible to moisture accumulation.

A damp environment is an ideal setting for spiders. So, if you’re thinking about how you can get rid of spiders in your garage, the strategies described below will assist you.

Numerous objects, such as plastic bags or old clothing around the house, may be used to conceal your shoes. However, before using any of these items to protect your footwear, you should first examine them for bugs.

Indeed, controlling the temperature may be the best way for you to get rid of spiders in the garage.

Additionally, you may use a combination of essential oils to create a fragrance that spiders despise. Use chestnut or peppermint oil inside a diffuser in the garage to get rid of spiders.

Vinegar is also an excellent natural spider repellant. In a spray bottle, combine white vinegar and water. Then spray this mixture around your garage, particularly at spider access sites like windows and cracks.

What Keeps Spiders Out of Garage?

What Keeps Spiders Out of Garage

Spiders generally get access to garages through cracks and gaps in the foundation and via doors and windows.

To keep spiders out of your garage, you can caulk these spots. But the most effective method is to remove other insects residing in and around your house. Outdoor lighting should be yellow or sodium vapor to diminish the environment’s appeal to insects.

Additionally, clearing dirt and wood off the outside of your garage can keep spiders away. Arachnids are also attracted to dark hiding spots; therefore, there should be a safe distance between these and your property.
