Flies and Their Control

Why Are Flies A Problem?

Flying insect pests in your home sometimes signal that something is wrong. This is because of these insects’ close association with all things smelly, dead and putrid.

Many different kinds of fly carry and spread diseases to humans and other animals. These insects carry a wide variety of dangerous bacteria, viruses and parasites outside and inside their bodies. If a fly lands on or in our food, then these harmful germs could easily infect us.

When a fly lands on a surface it tastes it with special taste receptors on its feet or it will vomit onto the surface. The vomit contains disease-causing bacteria and special enzymes to break down the substance and then it sucks it back up. Yummy!

Dangerous microorganisms include Salmonella, E-coli, Cholera and Typhoid.

What Are The Most Common Flies?

The most common flies that we identify as pests include

  • House Flies – these don’t bite and the larvae can thrive on many different foods
  • Horse Flies – these are predatory flies that bite humans to feed on our blood
  • Blow Flies – green and blue metallic flies with larvae that feed on meat
  • Cluster Flies – parasites of worms and overwinter in attics in their thousands
  • Fruit Flies – common nuisance flies in kitchens and bin stores

How Are Flies & Flying Insects Controlled?

Fly control is always a simple case of getting an accurate identity check. Once you know the species you will very quickly learn about its lifecycle and preferences. If you know what it likes, you will know where to look!

Occasionally the source of a swarm or infestation will be easy to find and remove, preventing future problems. Sometimes the cause is much, much bigger and control of the insects rather than the environment needs to be undertaken.

Pesticides should always be a last resort because these chemicals can be damaging to you as well as the pesky insects! Most control methods of this nature comprise sprays, fumigants and lacquers.

When pesticides are not available or safe to use, then we use electronic fly killers (EFKs), sticky flypapers or traps are used. Of course, there is one more rather obvious but often neglected method of control – exclusion! Exclusion in the form of netted screens over windows, vents and doors. Exclusion is good for the environment and for your budget.

What Is The Point Of Flies?

These common and abundant insects are cleaners, warning us of problems requiring our attention. In colder climates, these insects are also more important as pollinators than wasps or bees!

Elimination is usually easy – find the source, solve it, and these insects could magically disappear! A common flying pest is the British Isles that is found globally is the house fly. Take a look at this WHO (world health organisation) fly fact sheet.
