If you have ever wondered why flies get so big, here are a few reasons: Large flies need a lot of decaying organic matter in order to reproduce, which normally produces putrid smells. A mushroom body is also present in the brains of many insects, and this part of the brain is believed to influence their olfactory abilities. The fruit fly, or Drosophila melanogaster, is the perfect example of this, and recent research has shown that their sense of smell and memory are closely linked.
Flies are also opportunistic pests, and can enter the home through small cracks, screen gaps, or door openings. These can quickly become a major headache for the household. Luckily, there are ways to prevent flies from destroying your home. Start by cleaning up your yard and garden areas regularly.
Flies are often called filth flies, and can include house flies, bottle/blow flies, and flesh flies. Understanding the biology of these insects can help you control them and prevent them from ruining your home. Flies are attracted to moisture and organic material, and a female can lay as many as 500 eggs in her lifetime. The majority of adult flies spend their time hunting for food or breeding material. They carry up to 200 pathogens and about 1.9 million bacteria on their bodies.
As the sun goes down, house flies will crawl into buildings, usually through gaps or cracks. Once inside, they will cluster together in a sheltered place to hibernate until temperatures rise. They will also seek out windows with sunlight.
