Even if there was drift or tracking, the amount of pesticide that could get into the house is very low.
In addition, maximum exposure is at the site of application, the lawn. The maximum application rates for the lawn has already been determined through required EPA testing, including the determination that this maximum rate of application will not result in unreasonable risk to humans.
Any amount of product that might get into the house will be far less than the amount allowed on the lawn. Therefore, any potential risk will be far less, or non-existent.
