How do you catch a house fly?

Answer 1

Controlling fly populations can be as simple as controlling its ability to feed and breed. Flies eat decomposing organic matter, so don't leave any laying around. Keep garbage in sealed bags inside of covered garbage cans. Store the garbage cans as far away from your home as possible. Other organic items, like animal poop, should not be allowed to pile up in your yard. If your garbage becomes infested with maggots, get rid of it right away. Spoiled food inside your home should be thrown away immediately. Chances are flies have already laid eggs in it, and maggots are on the way.

Keep flies out of your home by sealing up any entry points. Flies are ridiculously small and therefore can find there way into your home through very small openings. Check for holes around windows and doors. Use a sealant like caulking to plug the holes. If there are holes in screens, patch or replace the screens. Check under your roof eaves for cracks, holes, or other entry points. Ventilation holes should be screened to keep flies out. Any point along the outside of your house where things, like wires and pipes, come in should be sealed as well.

Fly traps vary in size, style, and effectiveness. Fly paper works well in small, confined areas for smaller populations of flies as long as no more flies are getting in. Another good indoor trap is an ultraviolet trap. Flies are attracted to the UV rays, and once inside, they get zapped. For outdoor applications, inverted cone fly traps work the best. Make sure to remove all competing sources of fly food, like garbage, poop, and what not. The traps should be placed about 30 feet apart. Common baits used for these traps include molasses, sugar, fruit, and meat. Commercial fly baits are usually made with a pheromone that attracts flies very well.

Using insecticide spray should be reserved for when all other alternatives have been exhausted. For the most part, the use of insecticides in your home will be unnecessary. Introducing toxic chemicals into your home is never a good idea. For those of you who are afflicted with plague-like swarms of flies every time you step outside, insecticides may be your only realistic alternative. This is more than likely going to be done by professionals. They will spray either permethrin or diclorvos on walls were flies congregate.

biological control of house fly populations is an interesting technique. The release of a parasitoid wasp is not exactly an option for most people. But the practice has grown popular on large farms where enormous piles of manure make ideal breeding grounds for fly populations. The wasp finds a fly while its in the pupal state and kills the pupa by stinging it. Then she lays a single egg into the shell. Once hatched the wasp larvae feeds on the dead fly pupa and grows. A few weeks later an adult wasp emerges. Adult wasps are effective at decreasing fly populations because they kill any fly pupa they come across, even if they don't lay an egg inside.

Answer 2

Use a flyswatter. A rolled-up newspaper or magazine can work, but you'll need to move in close slowly, then swat quickly. (Flies can feel the air rushing at them as someone swats, which is how they get away in time. Flyswatters have slots built into them to prevent the air from rushing.)

Answer 3

With a flytrap. These are available commercially or you can make your own. The picture shows a simple cardboard flytrap used to catch fruit flies (the small hole in the inwards pointing "funnel" allows the flies in but they get stuck trying to get out).

One flytrap that is easy to make yourself uses a glass jar with a little sugar water (bait) in the bottom and an inward pointing "funnel" lid.
