Cluster Flies

Cluster Flies are relatively harmless and should not be confused with the disease-carrying housefly. However, they are awkward, noisy and their flying habits are slow. Cluster Flies do not carry disease and they are not typically harmful to humans, although their presence can be disturbing. Seeing dozens to hundreds of flies gathered on a window is indeed cause for alarm.

Cluster Fly Killer Kits
Cluster Fly Killer Kits contain all the necessary products required to control a cluster fly infestation. They offer a three staged attack against these annoying, flying insects, by combining the protection of a long-lasting residual spray, the deep penetrating power of a smoke generating fumer and an insect killing powder dust that can be sprinkled where cluster flies like to congregate.

Cluster Fly Killer Sprays
Insecticide sprays are the most common method for controlling Cluster Flies in and around the home. Most cluster fly killer insecticides contain strong active ingredients such as Permethrin, Tetramethrin or Cypermethrin. For best results against cluster fly infestations, we recommend using a spray with a quick knock-down together with a long-lasting residual spray for a combined attack.

Cluster Fly Killer Powders
Cluster Flies don't carry diseases, but they are no less annoying with their habit of clustering together in large numbers. One method of controlling these flying insect pests is by using powders or dust that can be sprinkled on surfaces where cluster flies like to congregate. Some powders are natural, and are insecticide free, making them ideal for use in chemical sensitive areas such as kitchens.

Cluster Fly Killer Fumers & Foggers
Cluster flies like to congregate in their hundreds in loft spaces. Smoke generating fumers and foggers are the ideal product for eliminating cluster flies in this environment. Once set off, the fogger or fumer will release a powerful insecticide smoke or mist into the atmosphere, penetrating the hardest to reach places in your loft space, killing all cluster flies in its path.
