Signs you have flies

A fly problem usually means a nearby breeding source, such as rotting food, a drain, bins or a dead animal in a void.

  • Large numbers of flies in one room or window.
  • Clusters of sluggish flies in lofts in autumn (cluster flies).
  • Tiny flies around fruit bowls or bins (fruit flies).
  • Small moth-like flies near sinks and drains (drain flies).
  • Maggots near bins or in voids.

Why flies are a problem

Flies land on waste and then on food, spreading bacteria that cause food poisoning.

  • They spread bacteria such as E. coli and salmonella.
  • A problem for food hygiene ratings in commercial kitchens.
  • A sudden infestation can mean a dead animal in a void.

How to prepare for flies treatment

Good preparation makes treatment work faster. Print this checklist and tick off each step before we arrive.

  1. Clear access to the areas where you have seen activity.
  2. Keep children and pets away from the area on the day of treatment.
  3. Do not use shop-bought sprays before the visit; they can make the problem harder to find.
  4. Empty and clean bins and remove any rotting food.

How long does flies treatment take?

Most domestic fly treatments take one visit of under an hour.
