High Toxicity, DDT, and Organophosphates: Banned, But Never Gone
Some of the first chemical pesticides used for termite treatments were composed of organophosphates– highly stable (and toxic) molecules that affect the function of cells in both insects and mammals. The last of the organophosphates were banned by the EPA in 1988; but they may still be in your yard, under, or around your home.
Isn’t DDT Banned in America?
Almost twenty years later , for instance, the University of Nebraska says there may still be a number of homes protected from termite damage by organophosphate termite treatments; which means these chemicals are still active in the ground, in the water, possibly in grazing animals, and may be affecting some humans, as well; though no research has been found to demonstrate the latter irrefutably.
While these chemicals-- the most infamous of all being DDT—were banned decades ago, it is more than possible that these termite control chemicals are still in the ground around a number of newer homes, but in some instances is very much likely.
Before you buy a new home, be sure to check for records on previous use of the land: obtain a history of termite eradication treatments; find out what kind of termite spray was used in the last treatment before 1988; and talk to local exterminators to find out what types of termiticides and treatment methods were popular in the area 20 years ago.
