Because it isn’t just rats that come into contact with rodenticides, these very potent chemicals have serious consequences for children, pets and for wildlife. These super potent variants have a longer half-life before they break down, which means they can stay in the environment longer and work their way up the food chain.
Amazingly, between 12,000 and 15,000 children under age six are exposed to dangerous levels of rat poison every year, according to the American Association of Poison Control Centers. From 1999 to 2003, 25,549 children under age six had symptoms of poisoning after exposure to nine rodenticides.
EPA says that rat poisons are the leading cause of pesticide-related visits to health care providers for children under age six. Low-income minority children are disproportionately at risk, one New York study found.
Children are uniquely vulnerable to pesticides. In terms of their biology and health, they are not just miniature adults. Their internal organs are developing and their enzymatic, metabolic and immune systems may provide less protection than those of adults.
Young children are at risk also because they may innocently handle the products, play on the floor and put objects in their mouths. EPA’s website says, “Adverse effects of pesticide exposure range from mild symptoms of dizziness and nausea to serious, long-term neurological, developmental and reproductive disorders.”
Under EPA Administrator Carol Browner, EPA announced a policy stating that regulatory standards would take into account children’s susceptibility or explain why that was not necessary and President Bill Clinton issued Executive Order in 1997 making this a government-wide policy, both good starts.
Because they are persistent, the products can stay in an animal’s body for six months or longer and work their way up the food chain. They are anti-coagulants and once in an animal’s system, they prevent blood from clotting. Rats that have eaten the poison might hemorrhage and bleed to death. They can stagger around dazed for days, making them easy prey for predators.
EPA biologist Bill Ericks in 2006 wrote that hundreds of wildlife poisoning deaths had occurred and that the pesticides had been found in hundreds of animals. “We’re finding this stuff all over the place,” said John Elliott, an Environment Canada scientist who co-authored an owl study published last year. “There’s a lot more rodenticides in the food chain than we would have ever thought. We’re surprised that there’s that much of the stuff kicking around.”
In 2011 EPA issued new rules, but they did not go as far as some wildlife advocates would want.
Reporting for Investigate West, Robert McClure wrote in December 2010 that the Clinton EPA required reformulation of the products to taste bitter, making them unpalatable when eaten and required the addition of a bright dye to better determine if children had put the substances in their mouths. But then the Bush EPA, after meetings with the industry, “reversed course,” according to McClure.
Manufacturers are still fighting, balking at responsible action.
While it’s been years without systemic government action, and it could be years longer, there are some steps you can take to protect yourself, loved ones and wildlife. Keep in mind the biggest risk comes from using these indoors, where kids are most apt to find them. But outdoor contact can happen too.

It’s the only thing about the Cards’ season that was stranger than Kyle Lohse becoming a solid starter.
It’s a squirrel.
The card commemorates Game 4 of the National League Division Series, when a bushy-tailed rodent scampered in front of the hitter, Cardinals’ utilityman Skip Schumaker, just before a pitch. Umpire Angel Hernandez called it a ball, and Phillies pitcher Roy Oswalt and manager Charlie Manuel argued, because everyone knows that a squirrel on the field means an automatic timeout, right?
Anyway, the so-called ‘Rally Squirrel’ became a folk hero in St. Louis (Twitter account here; 27,000 followers) and the most famous baseball-adjacent small mammal since David Eckstein.
With Squirrel Appreciation Day just past and Groundhog Day already upon us, we thought it was a good time to salute Rally Squirrel and take a look at some other notable baseball rodents.
Unless otherwise linked, all nickname information is from the Don Zminda’s “From Abba Dabba to Zorro: The World of Baseball Nicknames.”

Slow, slugging former Senators’ great supposedly got this nickname as a basketball player in high school because he “(hung) around the basket like a squirrel around a tree.” Though a citation eludes me, I believe he supped on nuts, seeds and cones throughout the spring as well, hoarding and burying food so that he might revisit his caches years later.
Early 20th century Cubs’ pitcher got this nickname because he was an agriculture student. Also: had a dense grey undercoat and digging claws. Alas, groundhogs may now be emerging earlier due to global warming, to their detriment—even worse than if Orval had reported for Spring Training in the middle of a Chicago blizzard (tip goes to Miles Grant for that tidbit as well as parts of this post).
Old timer was almost my height/weight twin, and nobody knows what made him muskrat-like. Perhaps his well-adapted swimming tail. Though even that would probably not have helped him escape calamities like the Kalamazoo River oil spill.

Former New York Giant was born 100 years ago last month and had big ears. I’m surprised there aren’t more nicknames in this vein.
Famous buzzcut Hall of Fame manager got this name for his extremely light blond hair. It’s also possible that his distinctly rat-like empathy contributed to his ability to rally a ballclub.
Slugging third-baseman got his Muroidean moniker for obvious reasons. And by that, I meant that he was omnivorous and a good burrower. What did you think I meant?

Honorable mentions go to to ‘Bunny’ Anthony Brief and Rabbit Maranville since rabbits aren’t true rodents but are often confused as such and often referred to together as members of the same ‘superclass.’
