Can Spiders Lay Eggs in Your Skin?

Last Updated: 27.11.22


Arachnophobia is not an irrational fear, therefore, if you dread the sight of spiders, investing in efficient natural spider repellents is the way to go. Plus, if you want to keep all kinds of bugs away from you, we have also prepared a guide that might come in handy, so check it out!

One of the most repulsive ideas one might come across when speaking or when thinking about spiders is the possibility that an arthropod of this kind might lay eggs in one’s skin. So, if this is a subject that haunts you, and you want to learn whether or not it is possible, keep reading!


Myth or fact?

We all have that friend who claims that a cousin of his/hers had a swollen cheek or jaw and that, after a visit to the dentist, she/he discovered that the area was filled with spider eggs. Although stories like this are likely to make the hairs on our skin stand up, it is comforting to know that they are just urban legends.

According to specialists, spiders do not consider the human body a suitable place for egg laying. The medical literature is void of cases that attest the existence of evidence that could confirm this myth.

The reason why this does not happen is that spiders are, by nature, reclusive arthropods that want nothing to do with humans in general. What is more, once they lay their eggs, female spiders do not abandon them. Laying their eggs inside the human body would make it inconvenient, if not impossible for a female spider to check on her young.



Where do they normally lay eggs?

After the mating ritual, female spiders lay a considerable amount of eggs in special silken sacs. The sac has the role of protecting the eggs from predators. Depending on the species of spiders one is dealing with, the dimension and the color of the sac can vary.

These cocoon-like sacs can be buried in the ground, they can hang on webs or they can be found in other locations, including in people’s homes. The normal hatching process also differs depending on the type of spider that you are confronted with. Some spiders take a few weeks to hatch, while others take months.

If you have noted the presence of spider egg sacs in your home, it is advisable that you remove them. To do so efficiently, it is recommended that you use a vacuum. After you have finished vacuuming the sacs, go ahead and empty the contents of the vacuum in a trash bin that is not located inside the house.


Signs of a spider infestation

Sure, seeing a spider or two around is normal. However, you should keep your eyes open to the signs that indicate that you might have a spider problem. For example, if your smoke alarm goes off constantly, although there is no smoke, chances are that spiders have crawled inside it.

As the experts argue, spiders might be attracted by the lights that alarms of this type include. When a culprit of this sort crawls inside the alarm, the system registers it and believes it to be smoke and, consequently, it goes off!

Plus, if you start to see more spider webs around and inside your home, as well as numerous spider egg sacs, chances are that you are dealing with an infestation.


How to control spiders?

As expected, the simplest way to control spiders is by limiting their access to food sources. By this, we mean millipedes, crawling insects and flies. To do so, it is best that you vacuum regularly and that you concentrate your attention on sheltered spots like in the back of cupboards, and under and beneath furniture.

Next, it is time to remove all the webs that you see. You should do so on a regular basis, as this will discourage the spiders from building new ones. Also, take the time to fill in the cracks in your walls and those around the pipework, as they might be used by spiders as an entryway.

Not all spider species are easy to get rid of. If all your efforts seem to be in vain, and you cannot actually control the number of bugs that live in your home, it is advisable that you seek professional help.

There are probably numerous exterminators living in the same area as you do that can help you get this issue sorted efficiently and in due time.

Are the spiders in one’s house dangerous?

The short answer to this question is most probably no. There are approximately 3000 species of spiders that have been identified in the U.S.A. However, only 60 of them have been labeled as dangerous.

By nature, spiders only bite when they feel like their life is in danger. Even if you have been bitten by a spider in your home, your life is, most likely, not in danger, as these arthropods use venom for hunting, and not for self-defense.

In the U.S.A, there are only two species of spiders that are venomous and dangerous according to the experts: the Brown Recluse, and the Black Widow. The Brown Recluse is usually encountered in the Midwest and in the south and the central part of the country. As its name suggests, this spider is reclusive and it rarely lives inside people’s homes.

The Black Widow is a species that you have probably heard about. Just like the Brown Recluse, this species is dangerous but quite rare. Cases of people bitten by it are very few.

Although both these species of spiders live mostly outdoors, there have been cases where exterminators found their nests in people’s houses. If you suspect that this is the case with your home too, it is strongly recommended that you call the specialists to get rid of the issue. Under no circumstances should you attempt to kill these spiders yourself.   


How to treat a spider bite?

If you have been bitten by a spider, there are a couple of steps that healthcare providers recommend that you take. Start by cleaning the bite with water and mild soap. Next, apply an antibiotic cream or ointment if you believe that the bite was caused by a venomous species of spiders.

You can also apply ice or a cold compress to the bite, as this will help reduce the swelling and the overall pain and discomfort that you are feeling. If the bite is on your leg or on your arm, it might also help to elevate it.

Over-the-counter medications such as pain relievers and antihistamine might also help. It is also recommended that you observe the evolution of the bite so that it does not get infected.

If the bite is accompanied by symptoms such as severe pain, nausea, vomiting, difficulty breathing or red/purple blisters, it is vital that you see a medical professional immediately, as your life might be in danger. If this happens, you should inform your MD that you have been bitten by a spider.

It should be said that the specialists claim that spider bites are not as common as people think. Also, in most cases, they are not dangerous and they can be treated at home.

Hi Kimberly. The answer is no, spiders simply cannot survive inside a human body.

Was bitten by a spider, not the first time, although later a bump grew from that area. I lanced a small part and pulled a blood and web blob filled with tiny little clear orbs…what spider would leave these behind???

Hi Marci. As I’m not a doctor and not qualified to give advice regarding this, I strongly suggest you see one in situations like these. Also, spiders don’t have the necessary anatomy to inject eggs into bite wounds.
