Well here is how I will be resolving this problem.
A 2 PRONG ATTACK.
#1) I will get some of the spray REPELLANT to try to drive them away from the areas that I really don't want them. (My daughter's play area is tops on that list because they have really made a mess out of that).
#2) The other prong will be death. I don't like the idea of drowning them because that seems to me to be suffering. Shooting them is viable, and I don't oppose it, but it is distasteful to both my daughter and the lovely Mrs_Bob, who will certainly hear the crack fo the .223. So I will try posioning them. I have to guess that we are overrun with the critters so we may be facing a population explosion based on how much grief we are getting this year.
I generally don't like posion because it is non-selective, but used properly and monitored I think it is a viable solution to reduce the population. I think it is probably more humane than trapping & drowning, or trapping & shooting. Head shots also run the risk of spreading rabies so a chest shot is much preferred to cleanly kill them. So I will have one of the rifles at the ready, complete with some good hollowpoints to insure a quick kill. But the weapon of choice is going to be poisoned bait, and a shovel to clean up the bodies.
There are too many kids around, and too many pets in the area to risk a population overrun by the cute little masked critters, especially given the risk of rabies and disease. I don't want to eliminate them, but they apparently need to be thinned down. Just like I have to live in harmony with them, they have to LIVE IN HARMONY WITH ME and my family and the other neighbors. This year there is NO harmony! I'd prefer if the coyotes got them instead of me, but I will do what needs to be done.
I just want to thank all of you for helping me identify what the real problem was/is. Now I have the task of dealing with it.
