A backyard bug repellent is derailing bumblebees' ability to navigate

In the summer, many people turn to mosquito repellents to reduce the insects' buzzing and bites. One solution that has become increasingly popular in recent years is the Thermacell device, which releases vaporized, pyrethroid-based insecticide prallethrin into the air.
