Small flies in the kitchen: find the source first

The word flyer refers to several situations

Small flies around a fruit basket, sink or pot of plant do not necessarily come from the same place. Treating them as a single problem can leave the source intact. Start by identifying areas where insects are clustering, and then look for what might maintain their presence. A photograph helps guide this verification.

The Track of Foods and Residues in Fermentation

The University of Minnesota describes Drosophiles as small flies associated with fruit, beverages and waste in fermentation. Check the fruit that is too ripe, the residue in the containers and the sorting bin. However, the presence of insects on a fruit does not prove that this fruit is the only source: examine all the accessible foods and waste.

Separate sightings near sink and plants

A concentration near an outlet or soil requires a different check than a fruit basket. Please note exactly where the insects are and take a photo. Do not automatically assign any small fly to the nearest pipe. For equipment that is difficult to access, check the installation rather than disassemble a siphon without being able to restore it.

A simple control plan for the kitchen

Remove the altered food and clean the contaminated containers according to their use. Identify the verified areas with a date, then observe where the presence is maintained. This organization helps not to repeat the same gestures every day by forgetting one point. Avoid product mixtures in evacuations: they can be dangerous and do not replace source identification.

When to ask for a diagnosis?

If insects return despite maintenance or affect several areas, send photos, dates and locations of groups. In professional kitchen, specify the waste circuits and schedules to organize the visit without exposing the food. Our insect control service in the 06 and east of 83 adapts the diagnosis to context. If you are looking at butterflies and threads in dry packages, see the guide food mites in closets.

Frequently asked questions

Are all the flies coming from the fruit?

No. The common term covers several insects. Their identification and their place of appearance guide the search.

Is a trap enough to remove the cause?

The capture of adults alone does not verify that the source has been removed. We need to look for what keeps them here.
