What Bugs Are Attracted to Humidity?

What is humidity? Humidity measures how much water vapor there is in the air. For example, when you use a humidifier or turn on your bathroom fan after showering, this causes the humidity levels to go up.

One of the main reasons bugs and other pests are attracted to humidity is that they need moisture to survive. Spiders, for example, need a humid environment to spin their silk web so they can trap their prey.

Roaches thrive in a humid environment as well. If the humidity levels are high enough, they can even survive without food or water for up to a month. This is why roaches are often found in kitchens and bathrooms since these areas have a high humidity level.

In addition, bugs like earwigs, centipedes, and mosquitos thrive in humid conditions. Stink bugs and boxelder bugs will also enter your home in search of a humid environment.

So, now that you know that humidity does attract spiders and other bugs, how do you keep them out of your home? Let's take a look:

Update Seals in Home

One of the first things you can do to prevent spiders and other bugs from entering your home is to check the seals around your doors and windows. Ensure that they are tight and no cracks or openings where pests can enter.

Watch Humidity Levels

Another way to keep pests out of your home is to watch the humidity levels. There should be a steady increase in humidity levels when using your humidifier. Still, if not, then it may be time to clean out the appliance and switch over to using a dehumidifier instead.

Spray Outside of Home

You can also try spraying outside your home where spiders and other bugs like to congregate. For example, you can spray near your home's foundation, in the eaves of your roof, and around any openings where pests could enter.

Keep Your Home Clean

Keeping your home clean will also help to deter spiders and other bugs from entering. Make sure to keep your kitchen clean, sweep and mop floors, and vacuum furniture and carpets regularly.

Take Out Trash Often

One of the easiest ways to keep spiders and other bugs away from your home is to take out the trash often. Make sure to seal the garbage can tightly so that pests cannot get inside, and take it outside as soon as it is complete.

Keep Windows Shut

If you live in an area where there are a lot of bugs and spiders, then it is best to keep your windows shut as much as possible. This will help to keep them from entering your home. Bugs and spiders will sense the humidity and try to enter the home through the windows.

Only Use Humidifier When Needed

Finally, you can also try to use your humidifier only when you need to. For example, if it is winter and the humidity levels are low but not extremely low, there is no need for a humidifier at this time.

On the other hand, if it is summer and there is a lot of pollen in the air, then using a humidifier may help to relieve some of the symptoms.

What Attracts House Spiders?

Spiders are attracted to different conditions depending on the type of spider. For example, some spiders are attracted to moist areas. This is why you will find them in basements and crawl spaces.

Whereas some spiders are more attracted to dryer spaces. In your home, this includes your vents and attics. In addition, you may have seen spiders on the walls in your room in the winter. This is because the walls are warm, and the spiders are making a home there to live.

How Do I Keep Spiders Out of my Vents?

You don't want to have spiders in your home vents. So how do you keep them out? The best thing to do is install mesh filters in your air vents.

This will help keep the spiders out and keep your vents clean. However, if this doesn't solve your problem, you will need to call HVAC specialists or Pest Professionals. They will be able to inspect the area and solve the issue.

Do Dehumidifiers Attract Bugs?

If anything, a dehumidifier is going to detour bugs from your home. Most bugs need moisture to survive. If you live in a region where humidity is high, then it is a good idea to get a dehumidifier.

Yes, a dehumidifier will help to keep roaches out of your home. It is a good idea to have a dehumidifier in your kitchen. This is the room where you will find most roaches.

A dehumidifier sucks in humid air from your kitchen and filters it through the machine. The water is then dumped into a container that must be emptied often. This helps to get rid of excess moisture in your home.

The humidity levels in your kitchen are perfect for the roaches to survive and reproduce. By having a dehumidifier installed, you will keep the humidity levels down and keep roaches out.

If the humidity levels go down significantly, the roaches will look for a more humid area. This may be your bathroom or another room in your home. To prevent the roaches from going to these other areas, you need to take some preventive measures.

You can do this by installing mesh filters in your vents or caulking up any cracks and crevices in your home. This will help to stop the roaches from entering your home.

Final Thoughts
