This is how I have constructed a simple garden trap and I will be comparing the results to the skinner that I normally use.
1) I purchased a plastic storage box with a clip-on lid from homebase for less than a fiver. The dimensions are 550mm long x 400mm wide and 300mm high. It maybe better to use a bigger one.
2) Two 8" diameter clear plastic kitchen funnels
3) Cut holes in lid to drop the funnels in. The funnels have been cut shorter so that the hole is around 40mm diameter
4) Position egg boxes, click on plastic lid and drop the funnels in the lid holes
5) A simple wooden frame with the lighting is straddled over the trap with the lights directly over the centre of the funnels. The 11watt actinics that i am using can sit 2 or 3 inches below the rim of the funnels. With the frame completely separate, height of lamps is easily adjusted
