Neighbor was complaining about "squirrels" in her attic at 0500 in the morning. Sounded fishy to me so I walked the perimeter of her house. One eave vent had definite signs of animal prints on the paint and a few louvers had been pushed apart.
Got her approval to set a 330 Conibear trap over the pushed-apart opening in the afternoon. Double wired it in place to make sure. This set of a Conibear uses the lure of outside plus the animals knowledge it had to force its way out. Checked it the next morning, nothing but this morning, the trap was gone, sucked inside the attic.
I took the lower louver off and managed to extricate the raccoon. Perfect neck snap and humane kill. I then went up into the attic to fix the problem with hardware cloth and 2" fence staples
. There were 30+ piles of raccoon dung ALL OVER the attic. All look like the animal had been eating dog food. Yes, she free-choice feeds her dog. And this was a yearling female, getting ready to nest.
I'm no stranger to raccoons in the attic, I went armed with my Para-Ord P14 and shotshells. I've used this pistol-ammo combination to kill raccoons in close quarters without worry about collateral damage. 1/3 ounce of #9 is sufficient with multiple rounds. I've used up to 9 to kill but then again, I'm not willing to mess with one in close quarters.
