Step 1: Mosquito/Insect Trap

Picture of Mosquito/Insect Trap
Cut the top (just before the start of the cone) off a 2 liter bottle.

Invert the cone and place it inside the straight part of the bottle.

Glue the two pieces together, using a glue or silicon.

Add 1 tsp yeast and 1/2 cup sugar to some luke warm water, and pour the mixture into the bottle.
Mosquitoes are attracted to the carbon dioxide that you exhale. The yeast feeds off the sugar and emits the same gas, so the mosquito enters the bottle, thinking she will find food there. She cannot then get out.

You can use the same bottle design for a fly trap, but fill it with a putrid smelling liquid. For wasps, use a sugar mixture. For fish, put under water, and add a bit of cheese or bread.
I have watched six videos of this on YouTube.com, but you are the first to say the mosquitoes are attracted to the carbon dioxide. Thank you, Andy Graham in Kara, Togo an area with Malaria. HoboTraveler.com

I was wondering if I could just staple all around instead of trying to glue would work?

Wasps also appreciate meat products, though I personally prefer to just go with apple juice.
for flys and gnats, use cider vinegar in the bottle. Some people add a little bit of sugar to the bottle too.

i did something like this to catch shiners for live bait but instead of sugar,yeast,water, mixture i used stale bread and i submerged it in the local pond.
how well did it work?
i got 2 or 3 shiners. fish dont like it because it is solid. they like things that water flows through.
what if I put small holes in it? that way the water goes through it.
that seems worth trying. it would be easier to use some sort of screen or mesh.
would it work in a stream or a pond? thx
any where that u see small fish will work. for running water u should weight it down. and your welcom

Might want to leave part of the top unglued so it could be emptied and cleaned.
