first thing to consider is the trap and the construction of it. I have used other traps but have found that the silver Gee's galvanized work best for catching anything that will squeeze into the hole. if you use the black traps you will find that the vinyl coating makes it smoother and more...
if you use the silver gee's wire trap they are less likely to get out. the sharp wire ends prevent them from getting out. also after swallowing the egg the snake is to big to fit even if it tries.
