How to make a trap for mosquitoes
In summer time, one of the main things that keeps people from enjoying their outdoor spaces is mosquitoes. Nothing ruins a backyard barbeque or even just a relaxing evening outside faster than a swarm of mosquitoes attacking your skin. While there are some solutions for a mosquito problem, most of them are pricey, made from possibly toxic chemicals, and require frequent reapplication.
If you’re looking for a chemical free and cheap solution to a mosquito problem, look no further!
Just like the pitcher plant, which lures bugs into its belly, this trap uses a bait liquid that attracts the flying pests into a plastic bottle with a funnel top that keeps them stuck inside. The best part? It only takes minimal DIY skills to make.
Materials for the trap:
A 2 litre plastic soda bottle
Scissors or craft knife
Black paper or other opaque material
You can use any type of plastic bottle, but we found that a 2 litre works best. Using your craft knife, cut around the top of the bottle just under where it starts to narrow into the neck. It can be helpful to draw a line with a permanent marker.
Take off the top. Turn the top of the bottle upside down and put it inside the body of the plastic bottle so it makes a funnel, then tape in place with your duct tape.
Cover your bottle with something opaque such as black or kraft paper, vinyl sheets, or even duct tape.
You can wrap it after you add the liquid to check the level of the liquid in the bottle.
The bottle needs to be covered because mosquitoes like dark places, and they will be more drawn to the bottle.
How to make the mosquito bait liquid
Ingredients for the bait liquid:
2 cups of water
3/4 cup sugar
1 packet “active dry yeast” (about 2 teaspoons)
Warm up about two cups of water. Pour 3/4 cup of any kind of sugar into the bottle and slowly add the warm water. Stir until the sugar is completely dissolved and then add one packet of active dry yeast, or two teaspoons if you don’t have the premeasured packets. This is the kind of yeast used for baking, not brewer’s yeast or nutritional yeast.
Pour this liquid into the container, making sure that it doesn’t reach the neck of the bottle, so the bugs have a space to fly all the way in.
Why does this mosquito trap work so well?
This trap uses the natural instincts of these airborne pests to draw them into a place they can’t escape. Mosquitoes are attracted by carbon dioxide, and the combination of yeast and sugar water releases this carbon dioxide.
The key to these traps is to put more than one out and combine them with other control methods. So while your DIY mosquito trap will catch some bugs for you, always remember to also pour out any standing water, plant mosquito repellent plants like lavender, or burn citronella candles. These DIY traps are a great addition to a natural mosquito control arsenal.
