Question from Bonnie Johnson
If pesticide was used in an apartment before you moved in how long would it take to go away and no longer be harmful. Are there any pesticides that are lower in toxins?
Debra’s Answer
Different pesticides persist for different lengths of time and if you can find out the name of the pesticide, you can look it up online and find out how long it persists before it biodegrades.
The length of time a pesticide persists is measured in “half life,” which is “the time when the expected value of the number of entities that have decayed is equal to half the original number.” It’s a probability, not an absolute. So minimum time before it will be gone is the half life number.
