The kind of rodenticide that could harm coyotes or bobcats (and that famously sickened the Griffith Park Mountain Lion) is what’s called a second-generation anticoagulant rodenticide. It’s been widely documented that this kind of poison kills the rat that eats it, but also hangs around in the dead rat so that any animal that eats the deceased rodent is also often killed. This is the rat poison that made the Griffith Park Mountain Lion P-22 look mangy, rough, and near-death a couple years ago, causing Glendale to switch up its rat-poisoning approach.
Online earlier this week, a rep for the neighborhood association countered assertions that they are to blame, saying that the pest control company they hired to put out traps switched in December from an eradication method that used these harmful anti-coagulant poisons to one that wasn’t toxic.
The new method involves putting out bait that turns rats poop a bright color (visible only when exposed to a black light); where lots of colorful rat feces are present, pest control workers lay plenty of the familiar “snap-traps.” But at least one local recently found a trap still baited with the harmful rat poison, making some wonder if all the traps were truly removed from the area.
