How often it is necessary to replace the rodent baits in bait stations if they still appear fresh? For how long shall the bait be available on a specific spot?
The baits in bait stations should be checked regularly, at least daily. If some bait has been eaten it should immediately be replenished. The baits should still be checked for 2-3 weeks after the last consumption of bait occurred, afterwards it is safe to remove the baits and bait stations. If you chose to keep them in place check them every month or even more frequently in order to spot the infestation as soon as it occurs. If the baits dry out or become visibly deteriorated replace them. The baits should be replaced every month or so even if they seem to be fine.
