Damp crawlspaces are an annoyance because they can cause a variety of problems, such as mold and deterioration. However, one of the most misunderstood problems it causes is excessive mosquito breeding. Understanding why moist crawl spaces breed mosquitoes (and what you can do about it) ensures that your home remains relatively mosquito-free this summer.
Why Moist Crawl Spaces Breed Mosquitoes
If your crawl space is moist, there's a good chance that much of that water is pooling up. And since crawl spaces aren't exactly a high-traffic area, that water stays still and stagnant. This is a major problem, as mosquitoes lay their eggs in stagnant water.
In fact, the scary thing about this is that most of these eggs can lie for months at a time before hatching. In the wild, they will survive through fall, winter, and early spring to start hatching. But the warmth of your home (and the dampness of your crawl space) will attract mosquitoes more than a frozen lake.
Sealing Up Your Crawl Space
The best way to keep mosquitoes out of your crawl space is to inspect it for holes and seal them utilizing exclusion techniques. Exclusion is the process of sealing cracks in your wall with mesh wire. This mesh wire is strong enough to prevent insects from muscling or chewing their way through. And the holes are small enough to keep out any insect.
Exclusion is relatively easy. All you need to do is stretch the mesh over the cracks near your crawl space, cut it off, and attach it to your home with staples or nails. Try to cover holes that are over 1/8th of an inch to ensure you keep out all other insects.
Other Treatment Methods
Exclusion should keep mosquitoes out of your crawl space, but there may already be a few mosquitoes lurking in your home or already buzzing around in your basement. Consider these alternative treatment methods after performing exclusion to ensure mosquitoes are kept out of your crawl space:
- Clean out your crawl space and dry up damp areas
- Install a dehumidifier near at the entrance of your crawl space
- Regularly disturb the water to kill any eggs
- Change other sources of still water in your home (to avoid attracting mosquitoes to your home)
The latter point is particularly important: if other sources of water are attracting mosquitoes to your home, there's no telling how soon they'll find their way to your crawl space. So make sure to avoid stagnant water in your sink, bathtub, or plants.
These simple control techniques are usually more than enough to help keep mosquitoes out of your moist crawl space. However, if you're still noticing an excessive amount of these buzzing pests in your home, it might be a good idea to call a professional, such as Bug Busters Inc, right away.
