Pests We Treat - Traps don't trick adult rats
At first, the owner did not want me to apply any rodenticide inside the building because he was concerned that rats would die inside, and the last thing he wanted was to compound the problem with rotting rat carcasses. I understood his concern, but explained that there would be a significant trade-off in effectiveness by not using product. As long as the carcasses are timely removed, it's generally not a significant issue, and it's well worth the trade-off of getting rid of these disease-carrying vermin. Nevertheless, based the customer's request, I initially set up mechanical "snap traps" above the ceiling tiles where the majority of the rat droppings were found. This method was fairly successful for capturing the juvenile rats that did not know any better. However, it was unsuccessful in capturing any of the adults. Adult rats are very wary of changes to their environment, and they are often not "tricked" by such traps.
