Fruit Flies and Food Safety

Although the fruit fly, also known as a small fly, has historically been considered a nuisance pest, recent research proves that small flies can contaminate food with bacteria carried from unsanitary surfaces such as trash, drains and mops.

Controlling Fruit Flies in Restaurants

You're enjoying a meal with friends at a restaurant and mid-sentence, you notice a fruit fly buzzing around in front of you. While you probably find this to be a nuisance, did you know it is also a sign of sanitation issues in the restaurant?

Commercial Small Fly Elimination

Small flies can live in your facility year-round. Harbored in small, tough-to-get-at areas like drains and beverage machines, these types of flies can quickly multiply into an infestation, drawing the attention of health inspectors.
