Bottle flies — also known as blow flies — generally feed on decomposed meat, garbage, and even on the wounds of live animals. When you notice bottle flies in your home, it usually means you have a dead animal or bird somewhere in your home. So, it’s important to know some things about these pests.
How to Identify Bottle Flies
Bottle flies are similar in size to house flies, but they’re easily noticeable due to their metallic blue-green color. These pests are usually 6-14 mm long. They have clear wings with brownish wing veins, dark legs and antennae, and large reddish-colored eyes. They can also be easily identified because of the loud buzzing sound they make while flying.
Behavior and Diet
Bottle flies can be found in almost every place inhabited by people and they’re common in populated areas. Because of their unsanitary lifestyle, they often carry bacteria that can be transmitted to humans and animals. They generally breed near or on decomposing matter or decaying meat. Bottle flies complete their life cycle in a short time since an adult female can deposit 200 eggs that become larvae in two to three days.
Where to Find Bottle Flies in Your Home
The most common sign of an infestation is seeing adults themselves or their larvae. Adult flies can be seen resting near decaying matter or on the walls. Their presence indoors usually indicates that decomposing material is present nearby. Often this means some kind of dead animal or bird is hiding somewhere in your home. When you notice them inside your home, you’ll need to thoroughly examine all garbage areas and sewer pipes. Also examine your attic, basement, and any other places throughout your home where an animal or bird could fit. Infestations usually happen during warmer months, when flies are active outdoors.
The Best Ways to Prevent Bottle Flies
These flies are also attracted to the light from windows during the day, so you can use fly-strips as a prevention method. However, this is only a temporary solution. Sanitation is the key to eliminating flying pests like bottle flies. That’s why you must eliminate feeding sources, so keep trash in containers with a tight-fitted lids, clean trash regularly, and always properly dispose of rotting produce. Also, keep window and door screens in good condition, without any holes or tears. Keeping other pests, like mice, rats, and birds, out of your home will also help prevent bottle fly infestations.
If you begin to notice large numbers of these pests around and inside your home, that is a certain sign of an infestation. Even if you see only a few of them, you’ll need to be careful and inspect your property immediately. These flies breed fast and they can quickly become a serious problem. If there’s an infestation, you should call a trained pest control professional to inspect your property. Bottle flies are unusual pests that do transmit diseases and it’s important to get rid of them as soon as possible.
