Fly habits & habitat

Houseflies never bite but use their mouth to suck liquids. They survive on liquid foods and eat solid stuff then need to regurgitate saliva on foodstuff and suck what gets liquefied with its proboscis. To make plenty of saliva house flies need water.

Houseflies excrete and leave behind tiny flecks. They deposit eggs on different objects like garbage, animal excreta, and yard waste. Female lays more than 100 eggs on decaying food source. The lifespan of a housefly is a maximum of 3 weeks in the cold season and a little less in a warm environment.

How flies spread disease?

House flies lay eggs on the garbage and animal droppings. When the eggs hatch, maggots eat decay around them and eventually transform into pupae. Ultimately, they transit into an adult fly with wings. After which the adult flies start searching for food source that generally include moist, decaying organic matter. The decaying matter has bacteria that are life-threatening to humans. When flies eat and regurgitate onto the new solid meal to liquefy and drink it.

The fly’s filth eating habit and spitting stomach contents on surfaces that humans contact frequently is the main way of spreading disease. For example, the flies sit on the food lying uncovered on the table. The illnesses are more than 60 but the serious ones include –

  • Cholera
  • Dysentery
  • Typhoid
  • Leprosy
  • Anthrax

Even if the fly did not eat food, it possibly left dropping laden with bacteria.

How to control housefly infestation?

  • Sanitation – Keep trash in tight bins or bagged properly. Compost piles need to be managed well. Isolating preferred food sources flies crave is a significant way to avert them.
  • Exclusion – Check around pipes for gaps, broken screens, and openings in the vents or conduits.
  • Traps – Use non-chemical traps to bait flies, so they don’t spread. Chemical traps that licensed pest control technicians apply last for several weeks when applied on the exterior of your home. Make sure that you use pesticides carefully inside the house. It is wise to have trained professionals to handle the housefly infestation issue.
