Why Are Spiders Attracted to My Car.

If you feel like you have to deal with a spider infestation in the car now and then, you aren’t alone. In 2013, Toyota fell victim to spider infestations. Here, spiders targeted cars’ air conditioners, and in extreme cases, they could make airbags burst unnecessarily. As a result, Toyota had to recall over 870,000.

Toyota wasn’t the only culprit, Mazda also experience it earlier on in 2011. Mazda recalled over 65,000 due to an arachnid infestation. Here, the Yellow sac spiders build webs in the crucial vent lines, which caused damage to the fuel tank.

However, this doesn’t mean spiders are only attracted to Toyota and Mazda automobiles—they can infest any vehicle they come across.

The reasons why spiders may be attracted to your car include the following:

  • In search of shelter: Spiders may be attracted to your car when it’s cold outside as they hunt for a warmer and safer hiding spot. In such a case, you shouldn’t be surprised to find spiders in car engines.
  • Dirty car: If your car is dirty or contains many unnecessary materials, it may attract these creepy bugs. The clutter in your car creates room for spiders to build their webs.
  • Idle cars: If you leave your car idle in spots where there might be spiders, you are likely creating an attraction for these eight-legged creatures.

How Do Spiders Get In Your Car?

Spiders get in your car through cracks and openings in most cases. If you leave your car’s window open, spiders are likely to use it as an entry point. Besides, if there are any cracks in your vehicle’s body, they also act as entry points.

Once spiders have managed to find a way into your vehicle, they can then easily relocate to different locations where it’s a bit warmer and damp, such as the vent, steering, or dashboard.

How Long Do Spiders Live In a Car.

So, let’s now answer another disturbing question, how long can a spider live in a car? If your car has favorable conditions, such as the presence of food and water, a spider can spend its entire lifetime trapped there.

Most spiders that invade cars have a lifespan of 1-3 years. However, this doesn’t mean they will disappear after this period because they often reproduce, leaving behind small spiders in the car to continue with the generation. But without food and water, most spiders can live between ten months to one year.

It’s also important to note that spiders can survive in temperatures as low as -5℉ (-21℃) to as high as 70℉ (21℃). Therefore turning on your AC may not affect the spider’s way of life inside your car.

Decluttering is one of the common and best ways to get rid of spiders in cars. If your car has any clutter or unnecessary waste, begin by removing it.
