I have stored several different sizes of Havahart traps.
I also suggest the two following books:
Also, get the following:
Brown's book contains detailed instructions for making--literally--over a dozen different types of snares, deadfalls, and fish traps.
I like Brown's book because the focus is on using natural materials which are--of course--free, and always available.
Benson's book is interesting because the focus is on gathering food animals in a clandestine, covert manner . . . so I believe that the two books compliment each other.
Both books are readily available in either electronic or paper format (I suggest paper), and I have experimented with some of their techniques and found them to be practical (I set snares with sewing thread, and watch animals get caught from a distance . . . through binoculars).
Part of my trapping equipment (besides the Havahart traps) is a cheap pistol crossbow that I can use to kill the trapped animal by shooting it through the spaces in the metal caging.
I like Havahart traps, as I can release the animal if it's appropriate, or observe the animal in a pen for symptoms of disease before I kill it for food.
The only deficiency--as far as I can see--is that neither book discusses gowns, face shields, or gloves.
I have those supplies as well, as I don't want to be exposed to diseases like leptospirosis, babesiosis, Lyme disease, typhoid, salmonella, and even (in the case of armadillos) leprosy (leprosy is the least contagious of all the contagious diseases, but why take a chance?).
