Many Wraith fans comment about taking more notice and care of insects, some of the smallest and most vulnerable of our fellow Earthlings. Andee has blogged about doing just that for stray bees in her place. Here is a video showing how to do it. One can also buy specially-designed catchers, but this method is just about free and has worked well for me since around 1992.
(My location doesn’t have any poisonous spiders or insects; consult with a local naturalist first if you are not familiar with the species in your area.)
