Before you can successfully get rid of the little flies taking control of your house, you first have to understand their patterns and behaviors, such as what they eat and where they hide?

For example, drain flies are attracted to sewage and sludge, so they often hang out inside sink and tub drain or basin. 

Garbage and Food Waste

Another huge attraction for little flies inside homes is where food and waste can be found rotting and decaying.

A location like trash bins, fruit buckets, or garbage disposals is all ideal locations for flies to flock to, providing a perfect spot for food and shelter.

Fruit flies are frequently seen hovering around sweet food items or rotting fruits. These same locations are also known as hideouts for fungus gnats, black flies, Phorid Flies, etc.

Your cupboards and pantries are also idyllic for little flies because they are dry, cool, and dark. It wouldn’t be a surprise if you walked into your food pantry one day and found some Indian moths inside your cereal, oatmeal, or rice boxes.

Most food cupboards and shelves will contain spilled food or open boxes, which is a calling to tons of flies looking for a quick and easy meal.

Potted Plants

Having potted plants inside your home is a great way to attract a large number of different insects. Many fly species will flock to your lovely house plants, including a few of the ones mentioned above.
