Step 2: How To Inspect For Cluster Flies

Commence your meticulous inspection within the confines of the indoor environment. Inspect attics, storage rooms, or wall voids for potential pest presence.

When spring arrives, pests will emerge from their hiding spots and gather around windows and doors. During the onset of autumn, pesky critters may be detected residing within the exterior walls of your establishment.

If you have a cluster fly infestation in your home, be aware that it will continue and return. Cluster flies have a strong affinity for a particular home, returning to it each year.

They cleverly release a pheromone that acts as a signal to other cluster flies, indicating that this home is an ideal spot for hibernation and protection from the cold.

We specialise in identifying and locating cluster flies and their elusive hiding spots. Our team of pest control experts is here to address the issue of cluster flies that may be causing disruptions during warm days in the winter or autumn.
