Best traps for fruit flies
Fruit flies are a common pest often attracted to garbage cans, fermented foods and fruit. While one or two fruit flies may not be cause for concern, they can quickly multiply until they’re flying around your entire home. Sometimes you only need to remove the source that attracts them. But if that doesn’t work, you’ll need a more tailored solution to get rid of these insects. One of the most common solutions is a fruit fly trap.
Causes of fruit flies
An adult female fruit fly can lay anywhere from 500 to 2,000 eggs in its lifespan. These eggs hatch into maggots within a couple of days and quickly grow into adults, ready to continue the cycle.
Unfortunately, it’s virtually impossible to see these eggs with the naked eye, so it’s hard to get rid of them before they hatch.
Fruit flies usually lay their eggs on surfaces near whatever source attracts them. Common causes of these insects include:
- Damp locations: Sink drains, toilet, trash cans, used cleaning rags, brooms, wet mops, garbage disposal, etc.
- Fermenting foods: Vegetables, ripe fruits, spilled wine and juice.
- Sweet items: Sugary drinks, other food items and crumbs.
If you have fruit flies, try to identify what’s causing them. Clean up any spills and make sure you dry out any wet objects. If the pests are hovering around the garbage, consider using a well-sealed trash can to keep them out. If you still can’t get rid of them, a reliable fruit fly trap can help. Worst case scenario, you might need to hire an exterminator.
Types of traps
There are a few types of fruit fly traps. Each one uses a different method to attract and kill the insects. The most common ones are:
- Liquid bait: You can use various nontoxic liquid baits to lure fruit flies. Most people use apple cider vinegar or regular vinegar mixed with liquid dish soap to catch the flies and drown them.
- Powdered bait: Powdered bait is another effective lure and uses ingredients that attract fruit flies, such as vinegar. Some also have toxic ingredients that kill the pests once they ingest the powder. Others use sticky tape to trap the insects until they die.
- Electric: Electric traps use a very strong light, similar to bug zappers, to lure fruit flies into a charged grid or a sticky paper strip. Some more advanced models incorporate fans to help draw in fruit flies.
- Color: Certain colors draw in fruit flies more than others. Combine yellow or blue colors with a thin, sticky strip, and you’ll have an inexpensive trap that keeps the insects from escaping.
When it comes to placing a fruit fly trap, you have several options. You can hang some traps around the house while others go behind kitchen appliances or underneath the sink. Others go directly into the garden or around indoor plants.
Certain traps, such as electric ones, require a nearby outlet to work. They’re also limited by the length of the cord. Sticky or color traps usually have stakes that go into the ground, so you should install them outside or in a potted plant.
Avoid placing traps near any food prep areas unless you’re dealing with an immediate problem. Fruit flies can carry different types of bacteria, such as E. coli and salmonella. If you put the traps on the counter, make sure to thoroughly clean the area before preparing any food.
The distance and range each fruit fly trap covers depends on the trap itself. Many manufacturers list the range in square feet on the label of the trap. For example, the DynaTrap DT3005W Dot Indoor Plug-In trap has a range of 400 square feet. If you need a wider range, consider getting two or more traps to cover the problem area fully.
Electric fruit fly traps will work as long as they’re plugged in or fully charged. Others only require you to refill the powdered or liquid bait. Most of these traps last between 30-45 days before you need to replace or refill them.
Certain traps, such as the sticky paper ones, eventually run out of space. When this happens, throw it away and get a new one.
