|With regard to Pest Free, I have been working with Coles Supermarkets for Seventeen years; Ten of these as the State Food Safety Manager.
Pest Free was introduced to me in the early stages as an alternate method of pest control, being keen to limit the amount of poisons used in retail, this looked like a great idea.
I recall having one problem store that I had been dealing with, where damage to stock was exceeding 5k perweek. This was going to make or break the commercial unit. I recall the first time is used the Commercial unit, read the book (yes actually did) plug it in and watch the change.
I still laugh when we saw rats physically travel to another side of a store; this took two weeks which the book said. When we plugged the unit down the other end of the store, once gain they moved again it was like herding sheep. Did not take long to work out two units are better than one and herd them out of the store. And did I tell you damage stock went to nil. Only complaints I had were from the tenants outside as this is where the rats went.
To date I am still using these units in Coles Supermarkets Qld and have a better record of pest than the other states. The only problem I get with the units is the Pest controllers turn them off.
