I am preparing my mosquito trap for the summer, we already have plants on the terrace that deter the little blighters.
Instructions for the home made trap
Required items Large plastic bottle, Brown sugar, Yeast and hot water.
Cut the bottle across 2/3 way up the bottle invert top of bottle and place in top of open bottle.
Fill to 1/3 depth with hot water add sugar and let it desolve then add the yeast give it a quick swish round to mix.
The gas given off the fermenting mixture attracts mosquitos big style they enter and axfixiate in the gas produced by the fermenting I suppose it might also work with Midges
