Ted, get 2 litre soda bottle and a dollar store LED puck lght. Cut the neck off the bottle at the very top of the cylindrical area. Put the puck
light inside. When it gets dark, run the trailer
furnace or an electric heater. In summer temperatures, you may not have to do this step, as the eggs are plenty warm for hatching. Next, turn on the puck
light, press the neck of the bottle into the main part to create a funnel. Place the trap near where you think the bugs are hatching. Sometimes it's hard to tell because they go to the
light during the day, which usually puts them behind the curtains at
windows or near vents with translucent covers. You won't catch them all but there will be less that have to be squished by hand. It took me about two weeks in May to get my brood from
fall 2012 hatched and caught (picked up in a local state park and at Owens Creek SP in MD). The "stink" doesn't bother me but it is an eye irritant so the less caught by hand the better.
