Moth Infestation in Bathroom Spaces: Here's What to Know
Usually, pestilent species of moths are attracted to spaces like attics, pantries, bedroom closets, wardrobes, and areas where dried food is stored. In these cases they will be either Clothes Moths whose larvae feast on animal based fibres and textiles, or Pantry Moths who lay their eggs near an unsealed food source such as grains, flour, nuts or even chocolate! However, some types of moths and flies infest bathrooms. There are a few reasons for this. In most cases, moths may be attracted to bathroom lights or linen closets. Drain moths, also known as drain flies, enjoy places where stagnant water and bacteria can be found.
What Causes Drain Moths/Flies to Infest a Bathroom?
Drains are a hotspot for bacteria and stagnant water. As such, insects are often attracted to drains that have been sitting unused. So, if you have a house with a bathroom or sink that isn’t getting a lot of use, these insects may make a home there. Basements or septic spaces are also attractive to these bugs.
Getting rid of drain flies can be a simple process. However, it will take some diligence. You will need to be consistent with treatment and be sure to remove as much bacteria as possible from any infested area. You will also need to treat all stages of an infestation, including eggs and larvae.
What are Drain Flies?
Drain flies are sometimes also called moth flies or sink flies. They are about the size of fruit flies, measuring no larger than 5 mm. They can be distinguished by their small moth-like wings and fuzzy torsos. These little flies are usually light gray, dark gray, or black. They are not great at flying and tend to hop around sinks and drains.
Drain flies can be found in outdoor sinks, indoor sinks, bathrooms, toilet pipes, kitchen sinks, shower drains, bathtub drains, basement sinks, septic tanks, wet soil, or any other damp area where bacteria may be growing. These flies may also be attracted to wet mop buckets or compost piles. Additionally, if you have dirty piles of wet rags in a sink near a laundry room or even sitting in a washer for a while, they can make a home there as well. These insects tend to be more active in the warmer months, but can infest damp areas year-round.
Primarily, these insects live on organic compounds found in stagnant water or damp areas where decomposing materials build up. They like to inhabit areas where they can feed on bacteria film, small scum particles, and so on.
