3 Genius, Foolproof Fly Traps to Make at Home
Flies are a common summer nuisance. They find their way into your house through open windows, tears in screen doors, or fruit from the store. Once inside, they seem to multiply quickly and take over. Getting rid of them can mean taking every piece of trash outside every day, cleaning your sink with bleach after each use, and keeping every bit of food tightly locked up. You may even turn to harsh chemicals and sticky fly traps.
Luckily, there are some simple solutions you can try, with materials you have around your house, before turning your life upside down to rid yourself of pests. Below are three homemade solutions to try.
What Kinds of Flies Are We Talking About?
These trap designs work for most types you find in your home: House flies, fruit flies, and bluebottles (blow flies). The only difference is in the type of bait you'll use.
How to Make a Bottle Fly Trap at Home
You most likely have all the supplies to make a homemade bottle fly trap on hand. All you need are:
- An empty plastic bottle of some sort—a soda, juice, or water bottle of any size.
- Something to cut with, such as scissors or a sharp knife.
- Some tape—duct or packaging tape works best, but even Scotch tape will do.
- And finally, you need some bait to attract flies. See the list of ideal fly baits below.
Now you're ready to assemble your trap.
- First, cut off the top of the bottle. Be sure to cut the widest section of the bottle, so when you invert the upper lid, it will fit without falling in.
- Fill the bottom half of the bottle with a few inches of bait mixed with liquid.
- Invert the top half of the bottle and rest it on the bottom half.
- Tape around the outer edge to hold it in place and make sure the flies can't crawl out.
Your homemade fly trap is done! Place it wherever you see a concentration of flies, such as next to a garbage can, sink, or fruit basket. They will be attracted to the smell and fly down into the bottle. Luckily, flies aren't the brightest creatures, and will be unable to find their way back out through the small hole. When enough flies have collected in the bottle, throw it away outside and set out a new one.
All About Fly Bait
What Do Flies Like to Eat?
Flies like to feast on organic decaying material (by "organic" I mean stuff that is derived from living matter, not things that were raised without pesticides).
- House flies and blow flies (blubottles) are attracted to fruits, vegetables, and meat. They love sweet things, so they'll suck anything from flower nectar to rotting fruit. As far as they're concerned, the riper, rottener, deader, and stinkier, the better. They're crazy about poop of all kinds and will swarm all over feces.
- Fruit flies prefer things that are sweet and/or fermented. They're attracted to fruits of all kinds, some vegetables, and anything sugary. They like juice, wine, beer, and cider, even when it's been left out for a couple of days, and they'll even drink vinegar.
All flies seem to be attracted to the stuff that collects in drains and garbage disposals.
What Kind of Fly Bait Is Best?
The kind of bait you need depends on what kind of fly you have. The better the bait is, the better your trap will be. You might try experimenting with several different kinds to find out which works best for you.
Bait for House Flies, Bluebottles/Blow Flies: A combination of sweet and meat probably works best to cover your bases. Mix scraps of meat (the older, the better) with something sweet (see list below). Lots of people swear by using rotten fish or shrimp, which probably work best because they smell so much.
Bait for Fruit Flies: Use fruit (the riper, the better), apple cider vinegar, fruit juice, syrup, wine, beer, or any combination.
Fly Baiting Tips:
- These traps hope to catch the flies in liquid, so whatever flavor bait you choose, make sure to float it in enough liquid to drown them. Water, juice, vinegar, or wine will do.
- To keep bees and other beneficial insects out of your trap, add a splash of vinegar.
- To help ensure that the flies drown, add a little dish soap to break the surface tension.
DIY Vinegar Fly Trap
A vinegar fly trap might be the easiest kind to make, and it's the best kind for fruit flies.
- First, grab a shallow dish or bowl.
- Put in some bait and fill it with an inch or two of apple cider, possibly mixed with some sugar.
- Next, add some fruit-scented dish soap to the bowl. The dish soap breaks the surface tension, so flies are unable to land on the liquid. Instead, they sink and drown.
This trap will work as-is, because the flies can't resist the smell and will dive right in just to drown in the liquid, but I suggest covering the bowl with saran wrap you have poked a few holes in (holes that are just large enough for the flies to get through). This way, all the flies that come to investigate will be trapped, even if they don't fall into the liquid. Some people say this method helps trap more flies, but others say fewer flies are able to find their way into the trap in the first place. If you're using the right kind of bait, though, that should be enough to keep them coming.
Make Your Own Wine Bottle Fly Trap
Fruit flies are most attracted to sweet, red liquids. Red wine works great, although white wine can work too.
- Take an almost-empty bottle and leave about an inch of wine in it.
- Next, find a large piece of paper and wrap it into a cone shape with a hole just big enough for flies to fit through.
- Place the paper cone in the opening of the wine bottle, and tape it in place if need be.
Once again, the inferior intellect of the fly will allow it to find its way in but not back out the tiny hole. Any cup or jar will work with this method if you don't have a wine bottle. Fill it with any sweet bait and liquid and put the paper cone on top. Place it wherever the flies are the biggest problem.
Flies are most active in spring and summer, and maggots are more likely to hatch in warm weather.
