After more than a month of sleepless nights, strange smells, and a full-blown wildlife standoff, the bear squatting under Ken Johnson’s home was finally shown the door — and it only took 20 minutes.

The breakthrough came Tuesday, when Johnson ditched bureaucracy and called in the pros from “The Bear League,” a Lake Tahoe-based nonprofit that specializes in emergency bear removals. The group flew in after hearing about Johnson’s ordeal.

“We heard about Ken, we felt bad for him and flew down and got the bear out,” said Ann Bryant, the founder and executive director.

Armed with paintball guns and experience from thousands of similar encounters, the team went straight to work. They fired paintballs into the crawl space until the bear decided it had enough and bolted.

“The bear was gone in 20 minutes,” Bryant said.

The paintballs weren’t meant to injure — just irritate.

The paintballs are filled with vegetable oil and sometimes “they hit the bear in the rump,” added Bryant — who said her organization does between six and eight bear extractions a day.

Once the bear was out, Johnson wasted no time turning his home into a fortress. He sealed the crawl space with two layers of plywood and sandbags. The Bear League added one more line of defense: an electric shock mat placed directly in front of the former den.

That mat proved its worth almost immediately.

The bear came back Wednesday, apparently hoping to reclaim its old rental — and got a rude surprise.

“He came back, and I was like, ‘oh my gosh.’ He hit the mat and scurried away into darkness,” Johnson said.

The electric mat delivers a mild but startling jolt designed to discourage animals from returning — a tactic increasingly used in bear-heavy regions of California.

Before The Bear League stepped in, the California Department of Fish and Wildlife (CDFW) had been trying to remove the bear for more than a month. Their attempts included scent spray and an elaborate baited trap stocked with sardines, fried chicken, shrimp, peanut butter and apples.

The plan backfired.

The trap eventually caught the wrong bear — a completely different animal that had been wandering the neighborhood.

Frustrated and desperate, Johnson said his life had been unraveling since Nov. 30. He described constant nighttime noise, sleep deprivation, strong odors and extensive damage beneath his house.

“It’s a lot more stressful than I thought,” Johnson said.

At one point, he even threatened legal action, claiming the state had abandoned the effort. CDFW strongly disputed that account.

“Despite very limited staff, CDFW biologists have been in constant communication with this homeowner since this bear was reported entering his unsecured crawlspace in November,” a CDFW spokesperson told The Post. “We remain committed to helping this homeowner and have never indicated otherwise.”

The agency declined to comment further on the eviction itself but confirmed the bear had indeed left the property.

The Bear League, which operates 24/7, says its mission is as much about education as removal. According to its website, the group aims to “educate people about the true nature of these animals.” Bryant said the organization has roughly 2,500 members and 220 trained volunteers — and handles multiple bear evictions daily.

Now that the uninvited guest is gone, Johnson says he holds no grudge — just boundaries.

But he’s clear about one thing.

“A bear is not a good roommate,” he said. “We’re meant to co-exist, not co-habitat.”
