I have a well on my property. Can my yard still be sprayed and is the pesticide application safe under this circumstance?

Beta-cyfluthrin has a strong affinity for soil and organic matter, which means its pesticide leaching potential (PLP) into groundwater is very low. If you do have a well along your yard edges (the area which will be treated), the commercial pest control operator will not spray within 5 feet of your wellhead. This is to insure that beta-cyfluthrin is not directly applied to your wellhead in case there is a cracked casing or other flaw in the well’s construction.
