The traps here are based on scientifically-proven designs adapted for use by anyone.  They specifically target the Aedes spp. carriers of dengue, yellow fever, etc. These are not your “yeast-sugar-pop bottle” designs that mostly catch sugar loving bugs.

Common Features

All the traps share some common features.

  • Glass or plastic container with smooth inside walls – females prefer rough surfaces.
  • A water bath with a little compost or grass in it to make it attractive to the females. Poison kills any eggs/larvae.
  • One or more landing strips of rough, heavy-weight “builders paper”, cloth or a wood stick. Poison kills females that touch it.
  • Black.  Mosquitoes prefer black.  But better to have a white bucket than no bucket at all!
  • Placed in shade and under cover to keep rain out.

The Basic Trap

Advantages: simple, easy to make using readily available containers.

This trap uses a 2 quart glass jar, like you might get pickles in.

The landing pad poison used is deltamethrin, in a product called Terro Ant Dust.

The water bath poison used is boric acid, familiar to us all as Roach Powder.

The Four Month Trap

Yes, you can make a trap that does not need refreshing for four months. The recipe is a bit more difficult because you must dilute the chemicals, and it is a great recipe for communities. It should not be used with traps smaller than 2.5 gallons.

More to come….

As we continue to study this topic, we will add variations and new ideas.

If you have animals you think might drink from a trap, cover it with a 3/4″ plastic or wire mesh after you make it, and prop it up well.  Or, have a tight fitting lid that you can drill lots of 2″ or 3″ holes in.  Even if the animals get into it, the quantities of chemicals are very, very small, in the range of milligrams.
