Why do I suddenly have flies in my house?
A sudden swarm of flies indoors usually means fly eggs have just hatched inside the property — commonly in bins, drains, or something organic decaying out of sight, such as a dead rodent in a wall cavity or loft. In autumn, cluster flies also enter homes in large numbers, gathering around windows and in roof spaces to hibernate.
How long does a fly infestation last?
Left untreated, a fly infestation can persist indefinitely: in warm weather flies complete a full egg-to-adult cycle in as little as 7–10 days, so the population constantly renews itself. After professional treatment, adult flies die on contact and the residual insecticide clears newly hatching flies over the following weeks.
How quickly can you get rid of a fly infestation?
Professional fly pest control can quickly reduce visible fly activity, but the time needed to fully control an infestation depends on the species and breeding source. Our exterminators target the affected areas and investigate where flies are entering or breeding.
How do I get rid of cluster flies in my loft?
Cluster flies hibernate in lofts, attics and wall cavities from early autumn, sometimes in their thousands, and they return to the same buildings year after year. Vacuuming removes small numbers, but DIY sprays rarely reach the whole cluster — professional treatment eliminates them, and sealing gaps around eaves, soffits and window frames stops next year's generation.
Why do flies keep coming back after treatment?
Flies may return when an underlying breeding source, food waste, moisture problem or entry point has not been addressed. Professional fly control focuses on identifying these sources rather than simply killing the adult flies you can see.
How many fly treatments will I need?
The number of treatments depends on the type and severity of the fly infestation. Some problems may require one treatment, while established or recurring infestations may benefit from follow-up visits to bring fly activity fully under control.
Is professional fly pest control safe for children and pets?
Professional fly pest control should always be carried out according to the product label and applicable safety requirements. Your exterminator will explain the necessary precautions, including any temporary restrictions for children, pets and other occupants.
What happens if flies return after treatment?
If flies return after treatment, contact us so the infestation can be reassessed. Depending on the service and treatment plan, follow-up visits may be available to address remaining activity and help identify why the flies have returned.
