The dark and damp environment of drains can attract a variety of insects, creating an unwelcome infestation.

Cockroaches

Cockroaches are notorious for their adaptability and can easily find their way into drains. They are attracted to the organic matter and moisture present in drains, creating an ideal environment for them to thrive.

Drain Flies (Psychodidae)

Also known as sewer flies, drain flies breed in the organic material that accumulates in drains. Their larvae feed on the sludge and gunk found in pipes, making drains a perfect breeding ground for these pesky insects.

Silverfish

Silverfish are moisture-loving insects that can navigate through drains in search of damp and dark spaces. They are attracted to the humidity present in drain systems and can enter homes through the plumbing.

Ants

Certain ant species, particularly those seeking water sources, may find their way into drains. They are drawn to the moisture and organic matter within the pipes.

Earwigs

Earwigs are attracted to damp and dark environments, making drains an appealing habitat. They can crawl through the plumbing and emerge in sinks, showers or other drain openings.

Reasons Bugs Enter Through Drains

Deep within the twists and turns of pipes, bugs are drawn by a simple force craved by all life forms – moisture. Drains, with their constant dampness, become attractive to insects seeking water. From the access outlets of sewer pipes, bugs make their way into our homes, enticed by the promise of a water source.

Yet, it's not just thirst that compels them. Drains serve up a hidden buffet of sludge and debris, a feast for bugs like cockroaches and drain flies. These creatures don't just use drains as pathways; they see them as convenient spots for a quick meal.

For certain bugs, drains can also become more than just a source of sustenance; they serve as protected breeding grounds. The drain fly, for instance, lays its eggs in the film that coats drain surfaces. Stagnant water and organic material turn our plumbing systems into perfect nurseries for insect larvae.

Basically, the dark and damp conditions within drains mimic the environments bugs naturally seek. It's a bit of a twofer for the bugs: the promise of shelter and food seamlessly integrated into the plumbing systems running through our homes.

Preventing Bugs from Coming up the Drains

While the drains might prove an attractive home for bugs, no homeowner wants them moving in. Fortunately, there are a range of simple, affordable steps you can take to keep creepy crawlies from living in — and climbing up — your home's drains.

Regular Cleaning

To prevent the buildup of organic matter, regularly clean and maintain your drains. Use a drain cleaner or a mixture of baking soda and vinegar to break down sludge and prevent insects from finding a food source.

Use Drain Screens or Covers

Install drain screens or covers to physically block insects from entering your drains. Screens allow water to pass through while keeping pests at bay. Covers, on the other hand, completely seal your drain when it is not in use. While it can be a bit of a hassle to constantly lift these covers up when you're using water and then put them down when you're done, they're a nearly foolproof way to keep the bugs at bay.

Fix Leaks

Address any plumbing leaks promptly, as standing water attracts bugs. Repairing leaks not only helps prevent infestations, but also preserves the integrity of your plumbing system.

Seal Entry Points

Inspect and seal any cracks or gaps in your home's foundation, walls or around plumbing fixtures. This reduces the likelihood of insects finding their way into your living spaces and then entering your plumbing system, where they can navigate their way through your drains.

Maintain Dry Drains

After use, ensure that sinks, showers and other drain openings are dry. Wipe down surfaces and eliminate any standing water to remove the attraction for bugs seeking moisture.

Bugs entering homes through drains can be a persistent issue, but with proactive measures and regular maintenance, you can significantly reduce the risk of infestation. If you’ve tried these methods and you still have a problem, seek out a professional pest control service, as they will be able to help you get things under control.
