Is it considered a trend If we are always finding evidence of field mice in the outdoor rodent bait stations? If the answer is yes, then what is our corrective action and preventative measure? I ask because we expect activity in these stations. We add bait to the stations to attract the rodents so they ingest it and die. The problem is that the field mouse population around the plant continually grows due to the nearby field, so we cannot prevent a reoccurence. Can anyone add some insight?
