How Long Do Blow Flies Live?
WouterMost people wonder, “How long do blow flies live?” The answer to this question may surprise you. While the adults do not live that long, the females can live for several weeks after laying eggs. They will spend the winter hiding in trees and will only fly on sunny days. Their lifespan is generally around two to three weeks.
The life cycle of a blow fly consists of three stages, with the first being the egg-laying phase, which lasts approximately 24 hours. The second stage is the larvae, which feed on wet or living flesh. The third stage of the blow fly’s life cycle is when they pupate and emerge as adults.
Blow flies are primarily found outside, in groups near animal carcasses, decaying vegetation, and garbage piles. They are often the first insects to attack a dead body, so you should keep a close eye on these areas. They may also infest your home by nesting in crevices or crawl spaces.
Another common way that blow flies enter your home is through a drain or sewer line. This can be a problem for homes with a septic tank. The larvae of these pests crawl up the sewer line and filter through your sink drains. Once they are ready to emerge as adult blowflies, they fly around your home and are difficult to identify.
