Some form of infestation is usually the cause of the rapid increase of flies in the household. It could also be nearby your property, so it’s best to check thoroughly around your place. Seeing a swarm of flies means dozens of eggs have already hatched in or near your property.

Houseflies feed and breed in filth, such as garbage, feces, rotting items, or spoiled food. Poor hygiene together with torn screens, and unsealed holes in doors or windows may lead to fly infestation.

Flies are likely to multiply in places like a garden, garage, house, or attic. So, these places should be searched first to confirm if the infestation is coming from any of these areas.
