Where Do Flies Lay Their Eggs? Understanding eating and breeding
patterns of certain flies can help when you need to eliminate
their populations. It is especially important to know where
certain species lay their eggs. There are several types of pest
flies found in North American homes. Filth flies include the
common house fly, drain flies and blow flies. Depending on
species, they may seek moist, dark piles of trash, rotting
carcasses or manure in which to lay their eggs. Fruit flies, as
their name implies, are fond of overripe fruit or other sugary
substances. Some biting flies require a blood meal in order to
trigger egg laying. To help control existing fly infestations
and to prevent future infestations, remove possible breeding
sites from your home. Continue sanitation after the infestation
has been eliminated to prevent future problems. Should an
infestation persist, contact your local pest control
professional.
