Kiko:

I don't think just one will be the perfect one. There are times where a trap is better suited to critter removal than a firearm. It all depends on what type of critter and where the pond is located.

Distance from you to the critter, other houses in the area, backstop, time that the critter is out, fur or feathers, etc., all play a part in your choice.

Some critters are on the Federally Protected list and need a permit to control. Others need the the State's blessing. There is the SSS method, but if seen, you could get into a LOT of trouble.

I've used:
Conibear 110, 220 and 330 traps
.177 scoped air rifle
.17 MachII
.17 HMR
.22 LR
.223
12 ga shotgun

The air rifle and firearms could be used as lethal or non-lethal methods. For non-lethal methods, you can use fishing line or an electric fence.
