Are There Flies In Your House?

Though many fly species may be present in homes, the house fly is the most common pest fly found in homes. Unfortunately the house fly is a big pest—not only because it is an annoyance, but also because house flies can spread organisms that carry diseases. In fact, researchers at the University of Florida have confirmed that house flies carry five additional bacteria species, each of which negatively affect humans. Flies in the house can spread pathogens, which are associated with a range of illnesses such as infections to food poisoning.

These filth-breeding insects typically reproduce in animal fertilizer. They’re also known for breeding in garbage among decaying matter.

Clearly it is important to get house flies under control. Indoors, the best bet is to use synergized pyrethrins or synthetic pyre­throids in the form of spray or aerosol. While these products quickly kill flies that get hit by the spray, they do not provide a permanent remedy to the problem. The products are most effective when sprayed in rooms that are closed. It’s important to note, however, that insecticides alone aren’t all that is needed to rid a home of house flies.

Preventative measures can help prevent flies from breeding. Because the flies breed in wet and rotting substances, taking sanitary measures is a huge step. It helps to refrain from leaving food lying around and to keep garbage sealed in a closed container. Garbage cans should be kept far from the house, and animal droppings should not be left to pile up. Food that has spoiled should be discarded immediately.

It can also help to use a sealant to close up any small openings around the outside of the house. Fly traps may also be used to control smaller populations of flies. These traps could include ultraviolet traps or fly paper.
