This squirrel learned to ring a bell when he wants nuts — and people are obsessed
A clever squirrel has gathered quite the TikTok following after he learned to ring a bell in exchange for nuts in California.
Researchers at UC Berkeley’s microbiology lab taught the squirrel to tug on a string tied to a bell to ring it from his perch on the window ledge, and rewarded him with a treat when he did, Alienor Baskevitch told CNN. The researchers named him Kluyver after famous microbiologist Albert Kluyver, the station reported.
Baskevitch posted a clip of Kluyver ringing the bell on TikTok, and it went viral. Users demanded to see a follow-up video of him receiving his hard-earned snack.
Others commented about how cute Kluyver is when he holds his little hands together and patiently waits for his treat.
“I would never get any work done,” someone said in the comments.
Since then, Baskevitch has posted daily updates of Kluyver stopping by around lunchtime and ringing the bell to be served his treat.
Sometimes it’s almonds, other times it’s pistachios. Several TikTok users suggested making the string longer so Kluyver wouldn’t have to work so hard to ring it.
Baskevitch tried giving him an upside down mug as a booster seat first, and while it took him a few days to learn to use it, now he’s quite the pro. She also caved and made the string longer, she said in the caption on the April 3 TikTok video.
“I think we don’t want the squirrel to rely on us as the main source of food,” she told CNN.

No household wants to face a pest problem, but over 14 million U.S. households encounter rodents, roaches, or other pests each year, according to the Census Bureau. These pests can trigger a variety of health concerns including asthma and may bring disease into the home. Once they establish themselves, pests can also damage the home itself and property inside.
Among the most common household pests are rodents and cockroaches, although termites also present a major threat in certain parts of the country. Seeking food and shelter, pests can creep into homes in a variety of ways, many of them related to the condition of the house. Problems like cracks or holes in a home’s walls, foundation, windows, or roof can provide openings into the home, while leaking water or sewer pipes provide the moist conditions that most pests prefer.
Given how pests establish themselves in homes, it is little surprise that pests—particularly rodents—tend to be seen more commonly in older units that have naturally deteriorated over time. More than one in five homes (22.7%) built before 1939 had a rodent sighting in the past 12 months, compared to just 1.8% of homes built since 2016. The data on home age and cockroach sightings is more complicated: cockroach sightings are most common in households built from the 1950s through the 1980s and less common before and after. This is likely in part because most of the oldest homes in the U.S. are found in areas where cockroaches are less common, while newer homes show less of the deterioration that allows roaches to enter the home.

For related reasons, a household’s income levels also bear a relationship to how frequently the home’s residents encounter pests. Among both owners and renters, the median income for households who had not seen a rodent or roach in the last 12 months was far higher than the median income for households who saw such pests daily. This is likely because households with greater means can afford to live in newer units or units that have been better maintained and keep up with the costs of ongoing maintenance and other preventive measures.

In addition to the age and condition of a home, where the home is located also impacts the type and frequency of pest issues. Rodents are usually more common in colder regions like the Northeast, where they seek out warm locations for shelter during the fall and winter months. Insects like cockroaches and ants thrive in warmer climates like those found in the South. And both roaches and rodents prefer more damp or humid climates, which make them less common in the dryer West. Taken together, these location-specific factors have a major impact on how likely a home is to face a pest problem.
To determine the locations with the worst pest problem, researchers at Construction Coverage calculated a composite index equally weighing the percentage of households with rodents and percentage of households with cockroaches for each location. The data used in this analysis is from the U.S. Census Bureau’s American Housing Survey. In the event of a tie, the location with the higher percentage of households with rodents was ranked higher. Only select metropolitan areas and states with data available from the American Housing Survey were considered in the analysis.
Here are the major metropolitan areas with the worst pest problem.
