Rodent Problems – Here is how to Fix Them

Seal all openings that are bigger than 6 mm (¼ in).
A mixture of steel wool and caulking may be used
for smaller holes.
» Regularly inspect and repair entry points by
covering with heavy gauge screening or 5 mm
hardware cloth or metal mesh, ideally woven and
galvanized to prevent edges from being gnawed
and to prevent rust.
» Use elastomeric sealants to seal long gaps, such as
those between walls and floors.
» Seal gaps anywhere pipes meet walls with
escutcheon plates, securing to the wall with screws
or sealant.
» Install sheet metal kick plates on door exteriors.
» Consider industrial door sweeps designed for
exclusion (not just weather stripping).
» Build outbuildings like sheds on concrete pads,
not bare ground.
» Native plants like wild mint are used by some
Indigenous peoples to discourage rodents.
» Prune back branches at least 2 meters from
balconies, eaves and roofs.
» Inspect and seal all structural lines that connect with
or enter buildings at any level, such as utility lines
and vents, pipes, electrical lines, sewer lines and
drains, cable lines, dryer vents and exhaust vents.
» Consider hiring a professional to identify problem
areas and design a long-term IPM strategy.
