Vendors often claim to practice IPM, even if they don’t fully understand the intent or requirements of it. This is due in part to the fact that IPM is still gaining traction in the industry. For example, if your pest control provider is regularly spraying pesticides, of almost any kind, on the building grounds, there is a good chance they are not following IPM—at least not to LEED standards. If that pesticide is not known to meet San Francisco Tier III criteria (see below), it is definitely not IPM.
