Bugs in the Bathroom & Kitchen Sink

Many pests are attracted to moisture underneath the sink and around the drain, an attractive place for pests to reside and breed inside your home. It’s important to take proper preventative measures to reduce the risk of attracting dangerous pests.

These pesky invaders include ants, cockroaches, silverfish and house spiders.

Bathroom & Kitchen Sink Bugs Identification


These tiny black bugs are often found near bathroom and kitchen sinks. However, not all sink ants are black! One of the most common species of ants you may find around your bathroom sink is the Pharaoh ant. These ants prefer to nest in warm, humid areas with access to water. They can often be found in wall voids, behind baseboards and under floors. If you have a leaky sink with cabinet storage underneath, you could be attracting Pharoah ants to their next home. They are not the typical black ant you’re used to seeing. Instead, their characteristics include:

Where Do Bathroom and Kitchen Sink Bugs Come From?

Because many of these pests are drawn to moisture, your bathroom sink can be a hotbed of pest activity. Leftover water in the sink basin or plumbing leaks can contribute to moisture buildup or even mold. These issues attract bathroom bugs like cockroaches, ants and silverfish, and their presence attracts predators like house spiders.

In most pest infestations throughout the home, pests tend to enter through any small cracks, crevices or holes in the walls or through gaps in window or door screens.
