Four packs are great for use in stables or around the average home. The kit comes with four stations that will last for many years, one round of baits and information on how to use them. The stations can be re-baited as often as is required for many years to come and provide a “window into the unseen”. Check the stations periodically or if you suspect any seasonal activity and keep the baits nice and fresh. Rodents like us prefer fresh food so the trick is to keep the baits fresh and palatable.
