When you live in Tennessee, you get used to dealing with humidity. Stepping outside in the summer can be brutal, but thankfully, we live in a time when air conditioning exists. Humidity is more than just a nuisance, though. It creates the ideal conditions for many of the pests that live in our area. While many homeowners take steps to prevent pests by addressing food sources and sealing entry points, moisture is one thing that often gets overlooked.
If you can relate, be cautious. Ignoring high humidity and moisture issues in and around your house can lead to major pest problems down the road. Thankfully, All-American Pest Control is a local Tennessee company that understands how the climate affects pest activity and how to protect your house through the most humid season of the year.
Why Does Humidity Make Homes More Attractive to Pests?
Although some pests prefer a dry environment, most require moisture for survival. Many pests can absorb water right from the air, so a humid environment is perfect to help them avoid dehydration.
Most pests need moisture in their living environment as well. Since Tennessee has plenty of humidity and rain, pests don’t usually have to worry about their nesting and harborage sites drying out. However, when we go through a dry spell, pests survive by moving indoors where they seek out a better, more stable environment. If your house is high in humidity or has moisture issues, those pests will stay inside where they will nest and breed.
How Does High Humidity Create Food Sources for Pests?
Even if you’re very careful about cleaning your kitchen, removing your trash properly, and storing food in airtight containers, you might still have a plentiful food source for pests right in your house. Humidity creates the ideal environment for mold, mildew, and fungus to grow.
Damp wood and drywall are common areas where this growth occurs. Certain pests, such as silverfish and beetles, will feed directly on these materials. In this way, humidity indirectly supports entire pest ecosystems. Even if you think your house is free of food sources, if you have any moisture issues inside, you may end up with a large pest infestation.
What Is the Stack Effect and Why Does It Matter?
The stack effect is the natural movement of air in and out of a building. In the winter, the warm indoor air rises, drawing colder air from outside into the lower levels of the home. In the summer, this effect tends to work in reverse. The cool air-conditioned air drops to the lower levels and warm air gets pulled into the upper levels from outdoors.
Unfortunately, when your house is in a constant battle with the hot, humid air from outside, moisture issues are nearly impossible to avoid altogether. Even if you don’t have leaking pipes, the combination of warm and cold air will create moisture in crawl spaces and living areas, which can lead to pest problems down the road.
Why Are Kitchens, Bathrooms, and Basements Common Pest Hotspots?
Kitchens, bathrooms, and basements have two things in common: They tend to be the most common spaces to find pests and they are usually the most moisture-rich rooms in your house. Do you see the connection?
Plumbing leaks, humid air from showers or cooking, poor ventilation, and condensation all lead to high humidity and moisture levels in these three spaces in your house. These rooms also tend to offer plenty of hiding spaces, whether under sinks, behind appliances, or in storage boxes, so pests find everything they’re looking for when they move into your house.
Which Pests Thrive in Humid Tennessee Homes?
While most pests prefer some humidity, some pests thrive in it. The pests that do best in humid Tennessee homes are:
-
Subterranean termites- These pests will dry out and die without moisture. Plus, they love to eat wood that is soft and water-damaged.
-
Cockroaches- Cockroaches love a moisture-rich environment and can often be found under kitchen sinks with condensation-covered pipes.
-
Silverfish- These pests require high humidity to survive. They’re often found in basements or attics where they’ll eat paper and cardboard.
-
Earwigs- These creepy-looking pests are often found in bathrooms where moisture levels typically stay high.
-
Centipedes- Centipedes like dark, damp areas, such as basements and bathrooms. You’re most likely to find them under sinks or in other high moisture areas.
Why Do Termites Benefit From High Humidity?
Termites are one of the most destructive pests to get into your house. Although they’ll infest a house without moisture problems, they’re more likely to get into your house if there is a lot of humidity or moisture inside. Here’s why:
-
Moisture softens the wood that termites eat
-
Water-damaged wood provides easier tunneling and feeding
-
With easier tunnel building, termite colonies can expand more readily
Unfortunately, once termites get into your house, the risk of structural damage increases exponentially. Although this damage won’t appear overnight, you can be certain that it is happening out of sight. The longer the termites remain in your house, the greater the damage will become.
Why Are Cockroaches Drawn to Damp Areas?
Cockroaches are dependent on water sources for survival. They will move out of their current nesting area if it becomes too dry, and will search for a new, moisture-rich space to live. When they get into homes, cockroaches often move into kitchens, bathrooms, basements, or laundry rooms. They will seek out the most humid environment they can find, nesting under sinks, in cabinets, in pipe chases, or even in drains.
Why Do Silverfish, Earwigs, and Similar Pests Love Humidity?
Silverfish, earwigs, and other pests also love moisture and humidity. These pests need at least 50% humidity to be happy, with many preferring levels up to 80 or 90%. When these pests get inside, you’re almost always going to find them in bathrooms, attics, basements, or laundry rooms.
If you find silverfish, earwigs, centipedes, or other similar pests in your house, it’s a sign that you have moisture issues that need to be addressed. Excessive moisture in your house not only attracts pests, but it can also be harmful to your home’s structure and your family’s health.
How Can Homeowners Reduce Indoor Humidity Levels?
You know it’s not good to have excess moisture or humidity in your house, but do you know what to do when those levels get too high in your house? There are several things you can do to lower the humidity levels in your house. All-American Pest Control suggests:
-
Using dehumidifiers
-
Maintaining indoor humidity between 30% and 50%
-
Running exhaust fans
-
Improving airflow in your house, especially in rooms that tend to be humid
-
Addressing plumbing leaks quickly
Humidity reduction is a proactive pest prevention strategy. The sooner you implement these suggestions, the better your chances of avoiding a pest infestation.
What Home Improvements Help Prevent Moisture-Related Pest Problems?
In addition to making changes to address high humidity in your house, you also need to address other moisture-related concerns if you’re serious about avoiding a pest infestation. Not only will taking care of moisture issues help prevent pests, but it will also make your house a safer, healthier place to live.
Ways to prevent moisture-related pest problems include:
-
Fixing leaking pipes and faucets
-
Getting your crawl space encapsulated
-
Sealing foundation cracks
-
Caulking around plumbing penetrations
-
Repairing damaged weatherproofing
-
Improving drainage around the home
When you implement these prevention strategies, you’ll reduce moisture and make it harder for pests to get into your house.
When Should You Be Concerned About a Humidity-Related Pest Problem?
Sometimes you get a pest in your house, but an infestation never develops. How do you know when the pests you’re seeing are a cause for concern? How do you know when the humidity in your house is too much? There are several warning signs you should watch for. They include:
-
Persistent musty odors
-
Visible mold or mildew
-
Frequent cockroach sightings
-
Silverfish appearing regularly
-
Moisture damage near walls or floors
-
Repeated pest activity despite cleaning efforts
All of these signs indicate that moisture may be contributing to a larger pest problem.
