Actualy the photo is when I built them a couple years back. They are nice and weathered now. Not sure what the count is, but its a bunch. I have a dozen of the boxes at work at any given time for gophers, red squirrels, squirrels, etc... They are effective. In reality they were made for weasel trapping in the winter, but decided there's no sense letting them sit if they can be used for summer work + get a good scent on them. As far as blood goes......not a big issue with a snap trap. Replace the trap when it starts getting too weak to keep the kills quick and humane.
