Insecticides For Flies: Products & Where To Buy

Fly control is vital. By using a proper insecticide you will eliminate the flies and protect your home or business. I recommend the Raid Indoor Residual Aerosol. It can be bought at most major retailers such as Walmart, Target, and Walgreens. It’s specifically designed to work inside homes and buildings, killing insects where they breed.

The housefly is a nonbiting fly measuring about 1/4 inch long. Adult houseflies have two wings and four lengthwise black stripes on their backs. The abdomen typically appears checkered.

Houseflies are often confused with flesh flies and stable flies. A flesh fly has only three stripes on its back, and the tip of its abdomen is usually red. The stable fly feeds on blood and its mouthparts protrude from the front of its head.

Life Cycle

Houseflies live for up to 3 weeks and are active during the warmer part of the year. An adult female deposits 50 to 100 eggs at a time and about 500 eggs over her lifetime. The eggs are deposited in rotting organic matter. They hatch after about 12 hours and the larvae, or maggots, feed on the rotting organic material. A maggot passes through three larval stages and then forms a pupa or cocoon. The adult fly emerges from the cocoon. Houseflies typically develop from egg to adult within 10 days.


Three types of control methods are used to suppress houseflies: cultural, biological, and chemical. It is best to use all three methods.

Cultural control

Cultural control means changing the environment to prevent houseflies from developing. The best cultural method is to properly dispose of any organic matter, such as vegetable or other food by-products, where houseflies might lay eggs. Place these materials in garbage bags and tie the bags securely. Remove all food residues and clean your garbage cans weekly.

Another cultural method is to keep houseflies out of homes and businesses by

  • keeping windows screened and doors closed,
  • placing exhaust (blower) systems above doors, and
  • installing doors that open and close mechanically.

Sticky traps and ultraviolet light traps placed around a home or business also can reduce housefly populations. Hang resin strips (flypaper) in infested areas where there is little or no air movement. A rule of thumb is to place one 10-inch strip per 1,000 cubic feet of space. Install the fly strips within 6 feet of the floor because the most fly activity is near the ground. The strips are effective for up to about 3 months or until completely covered.

Install light traps where they cannot be seen by flies outdoors to avoid attracting more insects to the building. To make the traps more noticeable to the flies in a room, place them at least 15 feet away from doors and other entryways and in darker areas away from bright lights and sunlight. Place the traps at least 5 feet away from food preparation areas to minimize the risk of food contamination. It is important to maintain the traps. Replace the bulbs each spring just before the peak season of fly activity because older bulbs lose their attractiveness to insects. Also, clean them out regularly because dead flies serve as food for other insects.

Biological control

Parasitic wasps and fire ants suppress housefly populations naturally. If you want to use this form of natural pest control, you can order fly pupae from insectaries in Texas or across the United States.

The pupae, which are already infected with the parasites, can be spread around homes or near where houseflies are developing. Place the pupae in areas out of direct sunlight where they will not be stepped on.

Parasitic wasps do not harm people or animals. They seek out and kill immature houseflies. However, parasitic wasps take time to work, and they alone will not eliminate a housefly population. Use this method in combination with other methods.

Chemical control

When necessary, insecticides can help suppress housefly populations. Fly baits, such as QuickBayt® and Golden Malrin®, are usually sugar-based and contain a compound that attracts adult flies. Flies that feed on these baits are killed by the insecticide they digest.

Many spray pyrethroid-based insecticides can suppress houseflies in and around homes. These products can be purchased at grocery and hardware stores. Be sure to read and follow the instructions on all insecticide labels.

Insecticide For Flies

Flies can be a nuisance in any home or business. They are attracted to waste and food, so they can quickly swarm around your garbage cans, food containers, or kitchen.

While they might just seem like an annoyance at first glance, flies can also cause health problems. They can spread germs and diseases. In fact, the fly species called “fruit flies” have been known to spread dangerous diseases such as salmonella poisoning.

You should take steps to get rid of flies as soon as possible if you notice them around your home or business.

The best way to get rid of flies is by using insecticides for flies. Insecticides are chemicals that kill insects like flies when they come into contact with them. There are many different kinds of insecticides available on the market today, so it can be difficult to choose one over another when looking for an effective way to kill these pests without harming yourself or anyone else who comes into contact with them after using it.

What Kills Flies Permanently?

Flies are a nuisance. They can spread disease, contaminate food and make your home or business look dirty.

There are many ways to get rid of flies, but some are more effective than others. Here’s what kills flies permanently:

Spray insecticide in areas where you see the most activity. Insecticides containing pyrethrin are effective on flies and other insects, but they should be used only as a last resort because of the potential for harm to humans and pets.

Lure flies into traps with sticky fly paper or fruit juice-based lures. Use sticky fly paper in areas where there is limited airflow or where you don’t want to use sprays or powders. Fruit juice lures attract flies and kill them instantly when they land on paper. These traps also work well at night when it’s difficult to spot flies wandering around your home or business premises.

What Insecticide Spray Kills Houseflies?

Houseflies are pests that can spread disease and cause problems in your home. They thrive in warm weather, but they can be difficult to get rid of. You may have tried to get rid of them by swatting them or sweeping them up with a broom, but these methods only work temporarily. If you want long-lasting results, it’s best to use insecticide sprays that will kill the flies on contact.

There are many different types of insecticide sprays available for killing houseflies, but it’s important to use one that is safe for children and pets. Some people prefer natural insecticides such as oil of clove or peppermint oil because they are considered safer than chemical pesticides. However, these products are not as effective at killing houseflies as other types of insecticides like pyrethrin or pyrethroids, which contain synthetic chemicals that mimic naturally occurring substances within plants like chrysanthemums and daisies.

You should also try using a product that has both residual and contact activity so that it will continue working even after the flies leave your home or office space where they were sprayed initially. This will prevent new flies from entering your home while also killing those already present.

List Of Insecticide For Flies

Insecticide products are typically sold as liquids dissolved in water or oils, although there are some powder formulations available. They may also be sprays or powders that must be applied directly onto the target area where they will dry within minutes after application before any harmful effects occur.
