Sorry, But Last Month's Polar Vortex Didn't Wipe Out 95 Percent of Stink Bugs

In the wake of the polar vortex that brought bone-chilling temperatures to the Midwest and Northeast U.S. last month, a silver lining appeared to emerge. Multiple media outlets recently reported that the weather phenomenon may have wiped out as many as 95 percent of brown marmorated stink bugs in areas that weren't accustomed to such frigid conditions.

Unless you like having your home smell like the musky, burnt-cilantro scent of squished stink bugs, we have some bad news: Those reports are not entirely accurate. According to KDKA Radio in Pittsburgh, the Virginia Tech lab experiment that has been widely cited in these articles is a little outdated, having been conducted in 2014.

At the time, it appeared to be a promising find. Researchers from the university had collected stink bugs, placed them in insulated buckets, and waited to see if they'd survive a particularly cold spell. Even though the insects were in a dormant state called diapause, 95 percent of them died when a polar vortex hit the region. That led entomology professor Thomas Kuhar to tell The Washington Post in 2014 that “there should be significant mortality of BMSB (brown marmorated stink bugs) and many other overwinter insects this year."

However, in an email to Mental Floss, Kuhar says the rehashing of "some media misquotes from 2014" led to these too-good-to-be-true reports being recirculated this week. "There is no new research on this topic," he writes. Furthermore, the lab experiment can't easily be applied to real-life scenarios because stink bugs tend to seek shelter during the winter. "Severe sub-freezing temperatures will negatively impact winter survival of these stink bugs if they were unable to find suitable shelter such as inside of houses and sheds," he writes.

These sentiments were echoed by entomologist Chad Gore of Ehrlich Pest Control, who spoke with KDKA Radio. "When they can find that shelter, they can survive the winter. Those that are exposed, they will freeze and we won’t have to worry about them," he said.

But is there still a chance we will see fewer stink bugs in the spring? Gore says don't count on it. "I’d love to be able to reassure everybody and say that 95 percent of all of our stink bugs are going to be gone, but that’s just not going to be the case," he said. "We’re still going to see them."

Even though stink bugs don't bite and are basically harmless (though they sometimes trigger allergic reactions), they can be difficult to trap once they've found a way into one's house. The invasive species is also harmful to crops—especially grapes—and sometimes end up getting pulverized and fermented in red wine. Suffice it to say, a lot of people would be happy if the pests suddenly disappeared. For now, though, we'll have to keep on dreaming.

Pet Obesity is Causing Big Health Problems, According to a New Report

If you’ve recently picked up your cat and felt your back give out, your furry friend may be among the 60 percent of the feline population that’s overweight. Dogs are also getting chubbier: about 56 percent of pet pooches are obese.

According to Banfield Pet Hospital, America's largest general veterinary practice with more than 1000 hospitals nationwide, those fat cats and chunky puppies are at risk for chronic health issues. In a new report, the hospital finds that osteoarthritis (OA) in pets is on the rise, with a 66 percent increase in dogs and a 150 percent increase in cats over the past 10 years.

Osteoarthritis is a kind of arthritis caused by inflammation or damage in joint tissue. Genetics, injury, or bone abnormalities can all be factors. The disease is chronic and degenerative and can make it difficult for pets to move around as they get older.

Excess weight can both precede OA and make it worse. When a pet is overweight, they can develop chronic pain that leads to stress on joints. If they already have OA, that joint discomfort can prevent them from being active, leading to weight gain. That worsens the condition, and the cycle continues.

A dog is 2.3 times more likely to be diagnosed with OA if it's obese, while cats are 1.2 times more likely. Dogs suffering from the condition tend to display symptoms like putting their weight off to one side when sitting, avoiding stairs, or appearing uninterested in playing. Cats might have loose or matted hair because they can't maneuver to groom certain parts of their body.

Although OA can be seen at any age, it’s often mistaken for old age and a pet slowing down naturally. If you notice your pet is either soft around the middle or moving more slowly, it’s best to see a veterinarian. Pets who are overweight or suffering from OA—or both—can benefit from treatments like special diets.

There Are 2373 Squirrels in New York's Central Park, Census Finds

Central Park in New York City is home to starlings, raccoons, and exotic zoo animals, but perhaps the most visible fauna in the area are the eastern gray squirrels. Thanks to a team of citizen scientists, we now know exactly how many of the rodents occupy the space—approximately 2373 of them, according to a census reported by Smithsonian.

In October 2018, a group called the Squirrel Census—with help from the Explorers Club, the NYU Department of Environmental Studies, Macaulay Honors College, the Central Park Conservancy, and the New York City Department of Parks & Recreation—organized a squirrel survey across all 840 acres of Central Park. For 11 days, more than 300 volunteers staked out their sections of the park twice a day—at dawn and dusk when the crepuscular animals are most active—and noted each squirrel they spotted. They also recorded how the squirrels looked, vocalized, behaved, and reacted to humans.

The research was analyzed and presented at an Explorers Club event in New York City on June 20. All the non-peer-reviewed findings—which includes a printed report, an audio report on a vinyl 45, 37 pages of data, collectible squirrel cards, and large maps of the park and the squirrel locations—are available to purchase for $75 from the Squirrel Census website.

This isn't the first time a massive census has been conducted of a public park's squirrel population. In 2011, the Squirrel Census launched with its first survey of Atlanta's Inman Park. They've conducted satellite squirrel counts at other parks, but Central Park is just the second park the organization has investigated in person.
