When it comes to the creepy crawlies in the UK, spiders are up there as one of the most feared. And it’s no surprise that people are questioning whether UK spiders can truly kill you. After all, our minds have been conditioned to think of spiders as these vicious predators with fangs that are capable of delivering venomous bites. But, is that really the case for spiders in the UK? Do they possess enough venom to cause serious harm to humans?
If you’ve ever spotted a spider in your home or garden before, you’ve probably had a mini heart attack. It’s not a pleasant experience to be caught off guard by these eight-legged creatures. However, not all UK spiders are dangerous or capable of harming humans with their bites. In fact, the vast majority of spiders found in the UK do not pose a threat to humans at all. But, there are a few species that you should be aware of if you happen to come across them in the wild.
So, can UK spiders kill you? Well, the answer isn’t a clear cut yes or no. It mostly depends on the species of spider and the person’s individual reaction to the venom. While there are spiders in the UK that have venomous bites, it’s very rare for these bites to result in serious harm or death. Most UK spiders generally want to avoid contact with humans and will only attack if they feel threatened or cornered.
Types of Venomous Spiders Found in the UK
One of the most common fears people have when it comes to spiders is the possibility of being killed by venom. While there are several species of spiders that are venomous, most of them are not deadly to humans. In the UK, there are only a few species of venomous spiders that you need to be aware of.

It is important to note that while these spiders are venomous, they are not as dangerous as some of the spiders found in other parts of the world. In fact, according to the Natural History Museum, there have been no reported deaths in the UK from spider bites alone since the early 20th century.

How to Prevent Spider Infestations in Your Home
Spiders are an important part of the ecosystem and play an important role in controlling pests. However, most homeowners do not want them inside their homes or living in their personal space. Fortunately, with a few simple preventative measures, you can reduce the risk of spider infestations in your home.

Place cotton balls soaked with these oils in areas where spiders are known to hide. Just remember to replace the cotton balls every few days to ensure their potency.
