Also done reading pc6 -- p 28/33 -- a good reference, indeed; though, no indication of low,med,high but there is a corresponding corrective actions.
please correct me if i am wrong, would this be applied in a specific location within the facility?
and..- for insects and arachnids -- the critical limit -- indicates "unacceptable increase..in activity" --- up to what % increase is usually unacceptable?
Well, the pc6 operational corrective control action is predictably similar in all cases (eg No.2). One would logically also do a RCA IMEX, (ie = Why?)
A typical trend anaysis sets an (acceptable) baseline then monitors for significant changes. I anticipate an (acceptable) baseline will vary with location/species/season etc.
(some trend examples are in 2 links in my referenced link). Corrective actions are based on individual reports (eg see pc3) + trends.
The setting of insect thresholds (and particularly the difficulties) with respect to trends,etc is discussed in detail in pc9. IMEX Pest Control Services use accumulated data/local experience to advise on this aspect. That's one way they promote their business.Go to the full post
