How to Get Rid of Cellar Spiders

Whether they live in your bedroom or your cellar, nobody really likes spiders. Not only do they look creepy, but they also make a mess of your house by building webs all over the place.

So, how to get rid of cellar spiders?

There are a few ways to go about it, but first, you should be able to identify what cellar spiders look like, and learn how to control their presence in your house.

Identifying Cellar Spiders

Cellar spiders are a common species of spiders that have very small bodies (only a few millimeters in size) and long legs. They are also often called Daddy Long Legs, which is a name you are probably more familiar with. They prefer to live in the dark, damp places such as basements, cellars, and crawlspaces, and build webs that are irregular and have no pattern, where they hang upside down while waiting for prey.

Cellar spiders are not dangerous, but they are pests. They do not have venom and are not strong enough to bite humans, so removing them from your house can be very easy. They do, however, build a lot of webs in a very short span of time. This is because once they capture prey in one web, they abandon it and build another one. This can cause quite a bit of trouble in homes because it will not only be a mess to clean up, but it is also not a fun job.

However, cellar spiders do help in getting rid of other bugs and insects, which they eat as prey, by capturing them in their webs and shaking the web to trap them further.

Should you remove cellar spiders from your house?

If you don’t mind cleaning up every now and then, and you don’t have a full-blown infestation, you may not mind having a cellar spider or two in your house. They are not dangerous, and they don’t pose any kind of threat. Though they do make a mess, they are happy with minding their own business and avoiding you as much a possible. A severe arachnophobe may want to remove them immediately, but if you don’t mind spiders from a distance, it may be better to let them be. Not only will they stay out of your way, but they will also help you avoid bugs and insects that can be a pest to remove.

How to Get Rid of Cellar Spiders

A cellar spider or two is okay, but if you have an infestation on your hands, you probably want to look into ways you can get rid of it.

Preventing Cellar Spiders from Entering your Home

One of the best ways to prevent a cellar spider infestation is to get rid of the habitat where a spider would like to live. A cellar spider likes humid, dark environments, so by taking away this habitat, by lowering the humidity, you may be able to encourage the spider to leave on its own. Additionally, spiders like to live in houses where their prey is close by, so if you take measures to remove these other insects, such as by changing your outdoor lights to attract less of them, you may be able to eliminate the spiders as well.

Clearing out webs

The first step to getting rid of cellar spiders is to grab a broom and physically remove the webs they have built-in your homes. This is a step you would be taking anyway since they make your house look messy, but it is also an important part of pest control. Not only will you be removing the mess, but you will also be ensuring that any future generations of cellar spiders are also removed in the process.

Since cellar spiders lay eggs in small silk sacs which are kept in webs, by clearing out the webs, you will be ensuring that any spider babies are also cleared out, which can ensure that you will not face another infestation in the near future.


You do not have to go as far as to use pest control products and services to get rid of cellar spiders for you. There are a few natural ways to get rid of them, a well as traps that you can set to capture these spiders and then squish them or let them out of the house.

After you’re done clearing out the webs, you can use a spider trap by sealing all cracks and crevices where spiders can get in, and place glue traps along the entryway. This way, not only can you avoid spiders getting into your cellars, but you can also monitor insect traffic and take the necessary action.

Spider Repellents

The best way to get rid of spiders – not just cellar spiders, but all kinds – is to use essential oils. Spiders hate many of these oils, and they are one of the best forms of pest control for spiders since they act as natural repellents.

You can use peppermint sprays by mixing peppermint oil with a few other ingredients and spraying them around your cellar, or directly on spiders if you see any to eliminate them faster.

You can also use garlic to make a spray that you can spray around the house to make the spiders leave on their own accord. However, garlic may not be the most pleasant smell to have around your home.

Another method to do away with cellar spiders is to use ammonia, which is one of the fastest ways to eliminate these pests from your house, though you will need plenty of ventilation for this. Once again, this can be made into a spray that can be sprayed over entryways or in places these spiders like to hide, such as pipelines and corners.


If you can’t be bothered to wait until all the spiders have left your house, you can turn to professionals, who are equipped with a variety of products and services to help you with pest control problems. Pest control companies will help you eliminate all spiders in your house using insecticides, which can also remove other bugs and pests at the same time, although you may not be able to enter your house or basement for a while.

There are also many pesticides made specifically for the cellar spider removal, which you can use to remove them from your house. However, pesticides are a short term solution and are not a substitute for sanitation. If you do not change your home environment to be less suitable for spiders, they will return.
