Fortunately, this is unlikely to be the final word on the subject. Earlier this year, the Maryland General Assembly was asked to ban chlorpyrifos on the state level. Lawmakers declined to do so, in part, because farmers argued that the pesticide might be an effective tool in combating the spotted lanternfly, an invasive species from Asia that first appeared in neighboring Pennsylvania and a handful of other states five years ago. Yet even today, Penn State Extension recommends a variety of treatments, including systemic pesticides (the kind absorbed by plants) like dinotefuran, imidacloprid, carbaryl and bifenthrin. In other words, if Maryland ever goes to war against this particular sap-sucking bug, chlorpyrifos isn’t important enough to risk serious health problems in children. There are many other options including, as Penn State still suggests, squashing the bugs manually.
