Does Hand Sanitizer Kill Spiders? What You Need To Know!


Is it true that hand sanitizer kills spiders? We’ve all heard this urban legend, and it’s likely to come up at some point, especially when we’re in a place with lots of arachnids. But how legitimate is the claim? Does hand sanitizer really kill spiders?

Hand sanitizer contains alcohol, which can affect spiders, but it’s not an effective or instant method of killing them. The alcohol content, especially if it’s 60% or more, may disorient the spiders but won’t necessarily kill them right away.

Although hand sanitizer can eventually kill spiders, it’s not the most practical solution. In fact, there are far more effective household products for dealing with spiders. If you want to know what these products are simply scroll to the bottom of this article.

How Much Hand Sanitizer Do You Need To Kill A Spider?

While we may be tempted to grab the nearest bottle of hand sanitizer and spray it directly at the spider, the question remains: how much hand sanitizer is needed to do the job? Well, the amount needed depends on the size of the spider and the potency of the sanitizer.

A minuscule spider would require a small amount of hand sanitizer, while a larger spider may need much more. However, even if you were able to cover the spider in sanitizer, it’s not a guarantee that it would actually die.

How Long Does It Take For Hand Sanitizer To Kill A Spider?

So you properly wondering if hand sanitizer could be used as a quick and easy solution? While it’s understandable to want to get rid of a spider as soon as possible, unfortunately, hand sanitizer isn’t the best way to do it.

Even if you were able to directly apply hand sanitizer to the spider and ensure that it covers every part of its body, it may still take hours or even longer for the sanitizer to ultimately kill the spider.
