You can do a lot to NOT encourage raccoons, opossums & skunks in your neighborhood by NOT keeping dishes of dog/cat food filled & outside, especially overnight. Also keep your garbage cans securely covered & not filled with fragrant garbage for too long. And encourage your neighbors to do the same. The populations of these animals has actually increased along with development, and sometimes their nocturnal habits change. I saw a report on TV about how a community was successful in eliminating a large proportion of skunk activity by just making those 2 changes.
I learned a handy way to bait those Hav-a-Hart traps, by setting it up on parallel 2X4s and placing the dish of bait UNDER the trap. Set something heavy like a cinder block on top to keep it from tipping over. Here I have to set the dish of bait, usually an open can of smelly cat food or sardines, inside a larger dish of water to keep the fire ants from swarming into the bait and discouraging the critter. Also, lay some feed sacks or something over the trap to disguise it.
DO NOT RELOCATE YOUR TRAPPED CRITTER!!! You can contact your local Animal Care & Control for suggestions & advice as to what to do.
Happy Hunting!
