What’s that buzzing around your kitchen? What is your dog chasing around the living room? What came in when you left the back door open too long? In many cases, the answer is the same: a fly.
Do Flies Hibernate During the Winter?
Have you ever noticed that house flies seem to disappear during the winter months? How do they manage to virtually vanish in the cold weather and then reappear in full force once weather starts to warm up? Read on to find out.
Fly Life Cycle
Flies have a short lifespan of approximately seven to 10 days, and the main goal of the species is to find a food source and breed. When winter is approaching, female flies will seek out a place to lay eggs that hatch into larvae. Flies prefer to stick with dirty areas such as fecal matter or garbage bins for egg laying. Flies are inactive at night, resting in beams, trees, shrubs, grass, outdoor wires and near ceilings.
Each female fly is able to lay between 100 and 150 eggs at a time, and the reproduction cycle of a fly allows each female to lay a total of about 500 eggs in her short lifetime. These hatched larvae, commonly known as maggots, consume large amounts of food before protecting themselves for the winter in a type of cocoon. Once warmer weather arrives, the flies will emerge from these cocoons to find food and reproduce.
Large flies that are known as cluster flies get their name because of their tendency to cluster survive the winter through their parasitic relationship with worms. The larvae live in the body of earthworms throughout the duration of cold weather. It is not uncommon for unseasonably warm weather to prompt adult flies to emerge and seek shelter in a building when the cold returns, so some homeowners may have to deal with the unpleasant surprise of harboring flies in the wintertime.
Some pests will seek out a warm place to live during the cold winter months. Unfortunately, heated homes could be a target for insects, rodents and other pests that are seeking winter shelter.
What Flies Do During the Winter
The common house fly spends the winter months in the adult stage of the life cycle in cracks and crevices, away from humans. In spring, these flies lay eggs on decaying materials. The cluster fly spends winter in diapause, a hibernation-like state of reduced metabolic activity. Once temperatures climb in the spring months, the fly’s appetite and development returns to normal. Unlike house flies, cluster flies prefer to lay eggs in the soil. Maggot hatchlings then seek an earthworm host. Once they find a host, they will eat their way from one end of the worm to another and pupate in the shell of the victim.
Risks Flies Pose to Humans
In addition to being a nuisance, flies can transmit disease. Flies pick up organisms while crawling and feeding on animal waste, garbage and sewage and deposit it on people or the food they eat. Illnesses flies can spread include dysentery, diarrhea, typhoid, cholera, leprosy and eye infections.
Fly Control Measures
Given the health risks that flies pose, many homeowners want to take steps to avoid having these buzzing creatures inside. To deter or trap flies, you can use fly swatters, automatic misters, sticky tapes or fly paper, baited traps or electrocuting grids. Keeping garbage and pet waste in tightly sealed containers that are regularly emptied can help prevent flies from sticking around. Make sure to clean out waste containers of residue that could attract these pests. Some people find success filling glasses with water and a few pennies at the bottom or repelling them with essential oils.
