Are these products safe if we have a well?
When considering the use of any pesticide on property that relies upon well water or has a well on their property present, certain factors that should be considered. First and foremost is the depth needed to reach the water in the well. Properties will high water tables – especially those where water is present just a few feet down under the ground – must be very cognizant of the well. In general, these properties will be limited in what can be applied to the turf for lawn care because of their well. But since most well water will be found a lot deeper and when the local water level is 50 feet or more deep, it’s not likely anything applied properly to the turf could leach enough to do any damage or pose a problem. In cases where contamination does happen to water that’s deep, it’s usually due to the liquid being applied finding a well housing pipe and if enough accumulates alongside the pipe, some can leak down alongside it and reach the water down below. To insure this doesn’t happen, you should stay at least 10 feet clear of any pump, well housing, well pipe etc. that you know of on your property and make sure treatments don’t run or pool down to the housing where the pipe is present.
Fortunately, most general pest control won’t pose any risk of well water contamination. In fact, when it comes to treating Stinkbugs, there really isn’t any need to be applying something to the ground. If you read through our STINKBUG CONTROL ARTICLE, you’ll learn there is only one type of spraying that should be done outside and this spraying should be done to the siding on the home and not the directly to the ground. This means there is no real chance of any spray making it’s way to your well water.
In summary, all the products listed are safe to use on and in the building and won’t pose a danger or risk to your local water supply when used properly. And for future reference, any fertilizer, insect control or other pest control done to your landscaping should be kept at least ten feet away from any well pump, pipe or housing to insure nothing makes it way down to the water below.
