Small openings around windows and doors provide easy entry for ants and cockroaches, which can fit through even the smallest cracks. Any opening larger than the thickness of a pencil can also be a rodent entry point. Flies are likely to come in through open doors and windows as well.
Floor drains are a hot spot for ants, cockroaches, and flies. Drains at the bar are also popular for fruit flies, which feed off fermenting fruit. These pests go after food sources relentlessly, so look behind and under the kitchen sinks and in cracks and crevices near any source of water.
The space behind the wall baseboards and floor tends to be a hub for insects, hosting all kinds of critters that crave tight spaces. For pests like cockroaches and ants, they serve as a highway to get to other places they want to go, like the kitchen.
Flies are among the filthiest of all pests and carry diseases from spending time in garbage, feces, carcasses, and food waste. When they make a pit stop on your patron’s plate, they deposit thousands of bacteria from their recent meal.
Many know that pests such as moths and flies are drawn to certain types of lights, so try to use less attractive lights like sodium vapor, and check and clean light fixtures frequently. While dead bugs may not be attracted to your food any more, the sight of them in light fixtures is not a pleasant sight for patrons.
