What Kinds of Bugs Does Moisture Attract?

The primary cause of bug infestations in homes, offices or closed areas is due to humidity and moisture concerns. Like every other species and living organism, bugs need water for survival. Insects and bugs are usually drawn to humid and moisture-prone areas; while most living species are attracted to water, some pests are more likely to be found inside homes. Bugs are mainly attracted to water and humidity because they need moisture from their surroundings in order to endure and survive. Not only are bugs attracted to damp areas inside the home, but they can also be detected in wet areas around the outside of homes. We suggest you keep reading to discover more about moisture-prone bugs, the leading cause of their growth, how moisture gets trapped in homes, and how to get rid of both the moisture and bugs.

Does Moisture In Your Home Attract Bugs?

It’s highly evident that bugs go wherever there is even a hint of moisture. If your house has water leaks and that area of the house stays wet – especially with hardwood – it is likely to attract a ton of bugs like woodlice, ants, termites, etc. Bugs that are comfortable with wood will be particularly interested in eating a wet piece of wood. The moisture locked up in wood softens it, making it easier to chew and grow on. Bugs can also rely on wood as a source of water and moisture, which boosts their growth. 

Bugs have a tendency to draw moisture from stagnant water for sustaining life comfortably. They usually avoid dry and warm places and get drawn more towards the moisture-prone parts of the house. The soil can also attract a ton of bugs as soil contains a good amount of moisture. A garden area with living plants and flowers is likely to have a denser population of bugs than the drier regions of a house. 

What Causes Moisture In Your Home? 

The formation of excess moisture in homes is due condensation. This happens when warm and humid air gets in contact with a cool outer surface. Other household activities like cooking, washing, and bathing trap a lot of moisture in the house. Some appliances like microwaves, AC units, heaters, unvented natural gas, and kerosene models also increase the moisture level inside and outside your home. 

Season changes also increase moisture. In winter, the walls, windows, and doors lack proper ventilation and insulation and remain cool, trapping more and more moisture in them. Then, during summers, water pipes that tend to stay cool increase moisture in their surroundings. Water droplets in these areas tend to drip and run down walls forming dewiness all over. This moisture attracts more and more bugs to your house.

Where Is Moisture Most Likely To Collect In Your Home?

Dealing with the moisture that gets collected in your house can be hectic and annoying. Particular areas in your home may tend to get more wet and dewy. Many factors add to the humidity levels in the house, which in turn increases the moisture in your house. The materials that were used to construct the concrete of your house can be one of the major causes of excess moisture. Then you need to take into account the climate of the area you are residing in. If you live near a beach or water body, you are more likely to face more moisture in your house. Another significant factor can be oversized and robust air conditioners and humidifiers in rooms. When a humidifier’s capacity is too large for a room, it forms moisture in the space. This moisture gets trapped and can cause a good amount of condensation in the room, eventually causing mold after a while. This can attract a lot of bugs to grow on the doors, window panels, corners, and other dewy areas. If you notice moisture in your home, consider having a humidifier installed.

What Kinds Of Bugs Are Drawn To Moisture? 

Although almost all bug species need water or moisture to survive, here are the 3 most common species to watch out for in your home.


If you’re noticing earwigs around your home, they’ve grown a colony in a nearby area. They like to generally nest in moist areas or leaves and can also make nests inside the house if there is humid space with some disarray for them to burrow in. They’re one of the most prevalent moisture-attracted bugs, as they always seem to be thirsty and constantly need water.  If you’re not sure what the bug in your home is, or if you think it may be an earwig but want confirmation, feel free to use our “Identify My Bug” feature and we can help you figure out what pest is invading your home!


Ants can be commonly found in homes due to food and other crumbs, widely found in kitchens and houses in general. In addition to that, ants can also be found in bathrooms and other comparably damp areas of the house. To prevent ants, you should try to keep the house clean and dry and don’t let mold form around the house. 


Cockroaches are bugs who love damp and moisture-prone areas. No matter how squeaky clean your house is, roaches are most likely to come into your home through pipes and water leaks, among other reasons. Cockroaches can also grow in cisterns, water tanks, and bathrooms. If you are not able to figure out the source of cockroaches in your house, you may need a pest control expert like Clegg’s to fix the issue. 

How To Get Rid Of Moisture In Your Home?

Start by fixing all the leaks and breaks in pipes. Try to find newspapers and cover all of them as soon as you can. Next, try to  Put a plastic cover over dirt clutters in crawlspaces to prevent moisture from developing in from the soil. Be sure crawlspaces are well-ventilated. You can also use exhaust fans or other resources of air in washrooms, restrooms, and especially kitchens to extract out moisture. Another quick tip is to dry your clothes in an open area rather than in rooms to quickly release moisture from wet clothes.
