In general, drain flies are not harmful to anyone. Adult flies and larvae are just annoying and can be rather dirty, yet they don’t bite neither can transmit any diseases. Still, they don’t eat feces or rotten fruits like other flies, all they need is a little stale moist in the house.

This is why kitchen drains, shower drains, garbage cans and other moisty areas in the house are perfect breeding grounds for them. Their larvae appear in these areas and they are relatively harmless to cats. If the drain is dirty, they carry that dirt on themselves which is pretty much the only concern.

Can Drain Flies Transmit Diseases or Parasites?

Drain flies are not known of transmitting parasites or diseases to humans nor cats. You can usually find them on the wall near the drain where they came from. Unlike some other flies, they can’t bite and have no interest in pestering humans or animals.

They are nothing to be afraid of, their presence is just a sign that there is plenty of filth in the drain they are coming from.

Can Drain Flies Transmit Disease through Cat Food?

Drain flies won’t land on any of the foods they can find in the kitchen, except if by accident. They are not going to transmit any disease or bacteria to pet food either. In some ways, these flies can even be useful considering that their larvae consume the gunk that has accumulated in the drain over time.

They prefer areas where they can find stale standing water. However, it is highly unlikely that the drinking water of your cat is going to just stand there untouched for weeks. Drain flies prefer filthy water full of organic material, otherwise it is unlikely that they are going to go near it.
