Drain Flies

These are other sink-loving insects.

Drain flies are pesky insects that tend to congregate around standing water.

Unlike their names they can’t fly, they jump and hop to move.

They are commonly called sewer flies, moth flies, and filter flies.

They thrive on moisture and debris and usually hang around drains that are not used very often.


Centipedes are big wimps who freeze in their place if you spot them.

Drains are their favourite place to hide as they are dark which makes it a great hiding spot.

They sleep during the day and loiter around your drains at night. When the master is away, centipedes are at play.

Fruit Flies

These are other very common insects that could be living in your drain. They choose drains to live in as they are dark and they prefer darkness to lay their eggs.

A shocking fact is that fruit flies can lay as many as 500 eggs.


They can be easily found in your kitchen and bathroom drains.

They are found in bathroom drains since they gravitate towards body odour, stagnant water and dirt.

The dirtier your surroundings the greater the chances of you encountering them.
