Squirrels. Because I hate them with a passion. I'm like Hitler when it comes to squirrels, ALL SQUIRRELS MUST DIE!!!!!
They did thousands of dollars of damage to my house between 2013-2015, years I was extremely busy at work in the oil refineries, and hardly ever home to snipe them out of my backyard. They literally chewed the siding of my house all over, in their attempts to get inside. I was lucky they didn't, and that they didn't get in the attic. Otherwise, I've read many accounts online of how they could've ended up chewing through wires, and burning the house down.
I'm not a carpenter or handyman, and don't have construction skills beyond small garage arts and crafts, like making birdfeeders and stuff. So it was over $4,500 to replace all that siding. That's money that could've been left in savings, or spent on a weekend vacation somewhere nice, or spent on AIR GUNS?
Thousands gone because of tree rats.
They've also destroyed my yard, which went from perfect and flat and level up until about 2009 when squirrels began invading my neighborhood, to a lumpy, bumpy, swiss cheese moonscape mess with hills and troughs and holes everywhere. They steal 95-100% of the fruit from a few fruit trees I have in my backyard, every year like clockwork, before they're ripe and my family can eat them. My Dad planted those trees before he died in '04, back when the worst thing around was the occasional mole making a few molehills in the yard once a year. No squirrels back then.
There's so many squirrels in my neighborhood, they've also decimated the bird population. There used to be songbirds and robyns tweeting and chirping happily all day every day in the spring and summer in years past. The last few years, it's been deathly silent. I learned just a couple years ago that squirrels will raid the nests of birds, and eat baby birds, and steal the eggs out of the nests and eat those too.
Last year, I lost track exactly, but I killed between 30-50 squirrels out of my backyard. A lot of that was trapping them in the live trap cage, then executing them with a bb pistol, but I also have a couple other air rifles, including my newest break barrel .22...already have 4 squirrel kills with that.
This year I'm going to buy my first pcp, within the next 2-3 months, and also a few more break barrels and bb pistols and revolvers.
No doubt there's going to be a fresh wave of the fat, nasty "yard gargoyles" as I like to call them.
My squirrel warfare arsenal is going to be growing by leaps and bounds this year, and I'll be ready for them...
So yeah, I really really really hate squirrels.
