The change in season can mean elevated
rodent populations due to cooler weather
and loss of habitat. Rodents will be
searching for safe and comfortable living
conditions, so you will want to minimize
all opportunities for them to gain access to

in small openings of 1/2” width or less. Use open cell
yellow expanding foam (Triple Expanding Foam) in larger
openings. Perform the task with care, keeping the foam
as neat as possible, avoiding jagged edges that rodents
can gnaw on.
Rotate bait active ingredient and presentation type.
If the previous rodenticide used was a “chunk or block”
bait, consider using a soft bait. Not a mandatory practice,
but the newer bait offerings gives this opportunity to
present an extra element of change to the rodents.
Check the active ingredient of the current rodenticide.
Make sure to change to a completely different active
Mow as much of the perimeter vegetation as possible.
Reduce the height to 5 inches or less, and don’t drive
through wet areas and create ruts which will hold water
or prevent future mowing.
Physically inspect each bait station. Verify the number of
bait stations present and their location. If bait stations
have been damaged, lost or are worn out, replace with
new stations. Make sure the stations are placed at the
correct interval and in locations likely to intercept rodents.
In addition, remove and discard the old bait, wipe or
brush out the interior of the station, add new rodenticide
according to the approved rotation chart.
Take a tour of the facility, inside and out. Make note of
areas that accumulate trash or hold seldom used items,
such as drums, pallets, sacks, pails, boards, cardboard, old
motors, etc. Take measures to remove, discard or properly
store as many of these items as is practical. Provide bait
placements near the remaining harborage areas
