I live in Florida and each spring/summer there is a lubber invasion. These are large grasshoppers that eat our garden and when full grown they are poisonous. And poison doesn't kill them when full grown. Nothing eats them except one species of birds that kill them, hang them up to dry in the sun which must extract the poison and then eat the Lubber. I have an airgun range in my yard but shooting lubbers with a pellet isn't practical or safe. I was wondering if an airsoft CO2 pistol/revolver shooting a plastic 20gr bb with a 300-350 fps muzzle velocity from 2-6 feet would terminally "whack" these critters. They are large and tough. I have to beat them with a brick or stomp on them if they are on something hard. Most of the time they take a severe beating before giving it up. Obviously a pellet would do the job but holes in the fence, outdoor furniture, clay plant pots or my neighbor's dogs and I will look like one of the deceased lubbers! Wondering if anyone had experience with using an airsoft gun for something like this.
