....can anyone tell me what the difference is between the various trap manufacturers? I'm a bit confused that there is such a price difference between some manufacturers on the same "type" of trap. I figure some are probably better than others, but what should I be looking for?
Thanks in advance.........

Also, is there one method of dyeing traps that is better than another, i.e. logwood crystals, walnut hulls, speed dip, ect?

Again, thanks in advance........
