What to do if rats and mice ignore our bait holders?

Rodent bait stations are an important part of Integrated Pest Control programs , both as a preventative and  control measure. Once installed, we assume that rodents will find them, enter them, and eventually eat the bait we have placed inside. But what do we do  if rats and mice ignore the  gadgets we have installed and refuse to interact with them?

What to do if rats and mice ignore our bait holders?

Bait boxes for rodents are common and very useful tools for the pest control professional. They are placed around or even inside customer premises to protect them from rats and mice. 

However, these products only have value in rodent control if they are able to find them, enter them and feed on the bait they contain. And, furthermore, the technician needs them to do it as quickly as possible, to meet the customer’s expectations of getting rid of the problem quickly.

In this sense, it is not so much about how many are placed but where and how.  

Since customers are not paying for a collection of black boxes but to eliminate their problem with rats or mice, the success of the service will lie not so much in the number of bait boxes placed, but in the experience to analyze the specific situation, read the signs of the colony, identify their activity zones and decide the most effective points to locate them.

In an article published in Pest magazine , one of the best-known rodent control experts in the US market, Bobby Corrigan, explains how to successfully use bait stations, taking into account scientific knowledge about the biology and behavior of rodents, which have much to do with their interactions with our bait stations. The principles that the expert exposes can be applied to both rats and mice, although the brown or sewer rat ( Rattus norvegicus ) stands out.

Over the past six or seven decades, scientists have been collecting information about rodent behavior in response to objects, such as bait boxes, suddenly appearing in their environment. Generally speaking, this behavior is complex and variable (sometimes significantly) from one rodent colony to another and depends on several factors. One of the most important factors is colony density, that is, the number of rodents that are sharing the same resources in a limited area.
