The DynaTrap attracts insects with a light, and then as they draw closer, they are further attracted by a special CO2-emitting metal coating that “mimics human breath.” Once lured into the trap, the insects are prevented from escaping by one-way doors and a fan. Once inside, it takes them about 24 hours to die.
I fully understand that some insects need killing, but watching a moth flop around and slowly die of dehydration is not my idea of a good time. If you are looking to run your own Insect Chamber of Horrors, get the DynaTrap. Otherwise, go for a good old-fashioned bug zapper.
