Flies in Your Restaurant or Kitchen? Find the Source

Flies feeding on food on a counter

Flies on food left uncovered.

The short version Flies in a kitchen or restaurant usually breed or feed nearby: in bins, drains, spills or food left uncovered. Swatting or spraying the flies you see doesn't fix the source. A daily routine for bins, drains and spills, plus physical barriers like screens, prevents most problems. For repeated problems, a professional inspection will find what you've missed.

Why flies are more than a nuisance

Flies land on waste, drains and dirty surfaces, then on your food and food-contact surfaces. Customers notice flies immediately, and a fly problem can damage your reputation faster than almost any other pest.

A daily routine that helps

Why spraying isn't a fix

Spraying kills the flies in the air, but new ones arrive as long as the source is still there. Long-term control means finding and removing the source, adding barriers, and treating where needed.

Different flies, different sources. Larger flies often come from bins and outside waste, while tiny flies around drains and fruit usually point to something inside. Identifying the type helps pin down where to look.

When you should call a pest control company

What happens at an inspection

A technician checks inside and outside the property, looks for signs of activity, works out where pests are getting in and what is attracting them, and explains what was found. You then get a clear recommendation. Protek Pest Services offers a free, no-obligation inspection across St. Kitts & Nevis.

Frequently asked questions

Why do I have tiny flies near the drain?

Small flies around drains and sinks often breed in the slimy build-up inside the drain. Cleaning the drain thoroughly is the first step.

Do fly screens help?

Yes. Screens and keeping doors closed stop many flies from coming in, but you still need to remove what is attracting them.

Can you help commercial kitchens?

Yes. We serve restaurants, bars, hotels, shops and other commercial properties across St. Kitts & Nevis.
