10 Simple DIY Mosquito and Fly Traps

DIY Mosquito fly Traps

Building your own mosquito and fly traps is simple, easy, and can usually be made with supplies and tools that most of us have at home. There are two elements to each design: 1) the housing, where the insects become trapped, and 2) the bait, the substance that lures them in.

These ten simple do-it-yourself designs for mosquito and fly traps will help you limit the number of pests in your home and outside without the need for nasty chemicals.

1. Inverted Pop Bottle Design

This design uses a 2-liter soda bottle that has the top half removed and inverted into itself to form a downward funnel that allows mosquitoes and flies to enter, but not escape.

2. Paper Funnel and Jar Design

This design is a variation on the Inverted Pop Bottle Design, but still uses the same principle. Easier to make, this design is quick to duplicate and works just as good. This is particularly effective against fruit flies. Use vinegar to lure them in.

If you need to buy vinegar as a lure, buy Bragg’s Organic Apple Cider with the Mother. Not because it will lure more flies, but because you can use it for your own health!

3. Cup and Plastic Wrap Design

For this design, you will need a cup or bowl, some apple cider vinegar or fruit juice, plastic wrap, an elastic, and a knife to make a few small holes in the plastic. Nothing fancy, but it will get rid of fruit flies fast.

Hey, look at that, the Braggs we mentioned!

4. Homemade Fly Paper

We have all seen fly ribbon that comes in small tubes that you attach and pull to dispense. They’re kind of gross, but man, are they effective. You just don’t want to get your hair caught in them!

You can also make your own flypaper. There is a short recipe to make the adhesive liquid that the paper will soak in, and allows you to create as many papers as you might need.

Homemade Fly Paper

Fly Paper Adhesive Recipe

Equipment needed:

  • a paper bag
  • a small pot
  • scissors
  • hole punch (ideally)
  • string or (as a prepper) Paracord
  • 1/4 cup of honey, 1/4 cup of sugar, and 1/4 cup of water


  1. Cut the paper bag into strips and poke a hole into one end for hanging
  2. Combine the honey, sugar, and water into the pot over medium heat until the mixture is fully blended together (sugar dissolved)
  3. Dip each strip into the mixture, so it is coated on both sides.
  4. Hang your strips up over something to catch the dripping mixture (newspaper should work fine).
  5. Once dry, hang them up where the flies fly.

5. Fly Repellent for Horses

Have horses on your homestead? You must have horse flies, too. Those things are brutal!

If you do not want to deal with making traps and cleaning them up, then making a fly repellant might be a better solution for you. This recipe can be quickly made. You will need to buy an empty spray bottle for spraying your horses.

6. Deet Free Homemade Mosquito Spray

It is easy to make your own mosquito spray that is free from the chemicals and fragrances that are added to store bought sprays. This recipe can be made in advance for mosquito season or camping trips. You will, however, need small spray bottles such as these.

DIY Mosquito Repellent


  • 2 tablespoons of witch hazel or vodka (yes, vodka)
  • 2 tablespoons of one of the following: grapeseed oil, jojoba oil, almond oil, or olive oil
  • 1/2 teaspoon of vodka (this acts as a preservative and is only needed if you’re using it in place of witch hazel)
  • essential oils of your choice

Directions: Add everything together in the spray bottle, but leave a little room for shaking it up. Shake up and spray.

7. Natural Mosquito Repellent

This design is probably the simplest mosquito repellent ever. To make your own, all you need are some limes and a handful of whole cloves. You cut the lime in half, insert the whole cloves, and place around your patio or garden. Easy peasy!

8. Ziploc Bag Fly Repellent

This design just requires a Ziploc bag half full of water and a couple of pennies. Hang it near an area that you want to be free of flies, and they will stay back.

Sound strange? I thought the same thing. Apparently, flies are afraid of the water and then get confused by light hitting the pennies and the water. Needless to say, it works best where the sun will hit it.

9. Fan and Screen Mosquito Trap

To build this design, you will need a box fan, magnets, and a screen. You will need to make a spray bait that will attract the mosquitos, and the fan will take care of the rest. Follow Wiki’s lead on this one.

10. Cone Trap Design

This design in a heavy-duty fly trap, and is great for areas that have larger than normal fly populations.

A wooden frame holds a mesh cone in place over a pan of bait to capture and collect flies, making this model more complex than the others, but able to handle a much larger amount of flies. Follow the school’s lead to build this one.
