In the summer months household flies seem to be every where. They are seen inside buildings, around picnic tables, lunch areas, anywhere we gather and there is food.
Household flies suck liquids containing sweet or decaying substances. Larva feed on moist food rich in organic matter. In the summer months they are found outside in garbage, manure, anywhere there is decaying matter.
The female lays 5-6 batches of 75-120 white eggs on moist manure or garbage. Eggs hatch in 10-24 hours. Larvae reach full size in 5 days emerging as adults about 5 days later. Males live for 15 days, females up to 26 if they have access to milk, sugar, and water.
Household flies can transmit typhoid fever, cholera, dysentery, pinworms, hookworms, and some tapeworms. House Flies are regarded as a greater threat to human health than most other insects.
The key to controlling flies is to remove organic matter, ensure general sanitation is good, and to ensure screen doors are in place to keep all pests out.
Cluster flies are annoying and frustrating to eliminate because there is no easy answer to how to get rid of them.
The problem is that female cluster flies lay their eggs in soil but once the larvae hatch they burrow inside earthworms which then serve as a food source to the developing maggot. After a month or so the maggot develops into a full blown fly. The only way to get rid of the maggot is to get rid of the earthworm host. But earthworms are so beneficial to the garden that to get rid of them would be environmentally unsound. Each year, beginning in spring, up to four generations of cluster flies may emerge from your soil.
The best policy is to prevent infestation by controlling cluster fly populations before they get out of hand. And here is where Peregrine can help you.
What to look for
Typically, as the cool fall days approach, cluster flies gather together on the south and west sides of a building, often close to windows and door frames, preparing to hibernate in gaps in the side of the structure. They particularly like to pass the winter in the voids in older frame buildings and other sheltered areas such as behind curtains, under shelves, dark corners, etc.
On warm winter days or as spring approaches the cluster flies emerge and crawl across walls and windows, becoming more active as they warm up. They are attracted to light so you may find collections of dead cluster flies lying beneath a left-on light bulb in an attic or shed, for example.
What we can do to help
Peregrine’s skilled technicians are trained in eliminating existing cluster fly populations. They will also identify and seal possible future entry points and will apply special repellent products to prevent future infestations.
