H. R. 230 has been proposed for the US Congress to ban all use of the pesticide chlorpyrifos. Basically:

10 chlorpyrifos shall be deemed to generally
11 cause unreasonable adverse effects on the environ-
12 ment due in part to dietary risks to humans posed
13 by residues of that pesticide chemical on food;
14 the Administrator of the Environmental
15 Protection Agency shall cancel the registration of all
16 uses of chlorpyrifos…

Contact Chester County rep Chrissy Houlahan to ask her to support the bill here.

Although the EPA banned most residential uses of organophosphates like chlorpyrifos in 2001, it has so far been turned back in banning chlorpyrifos in agriculture and mosquito control.

Although Chester County has not been spraying chloripyrifos to try to kill adult mosquitoes, nothing currently prevents it from doing so.
