Hi,
I agree with Jackson, make your own, can work out far cheaper as well. All I do is simply get a nice strong torch, make sure it's got new batteries, wrap a large piece of plain paper into a cone shape on the end of the torch, tape it on or use an elastic band, switch the torch on and point slightly upwards at an angle and leave for a few hours through the night, gets me many goodies. The cone quickly fills with little moths and bugs like lacewings etc.
Regards,
Dave
