When javelinas are outside traumatizing your travel trailer, and stinking with their musky nose-curling odor, use a flashlight to light your face, make yourself big, wave your arms, growl and bark like a big wild canine. Throw in a cougar growl or two, and flail about lighting yourself up like a mad animal gone rabid.
That usually sends them running.
Baby javelina: “Mom, what was that loud ‘thing’?”
Mom javelina: “It’s okay, dear. Just some insane human trying to be like us. Just waddle along, humor it and it will go back inside.”
