Methods of deployment are either bait stations (tamper proof bait boxes), bait points (an arrangement that uses materials and the local environment to restrict access to the bait), loose but inaccessible (an arrangement that uses the local environment to restrict access to the bait) or sewers.
Bait stations should be labelled with the following information: 'do not move or open', 'contains a rodenticide', 'product name or authorisation number', 'active substance', 'in case of incident call a poison centre, UK: 111'. The product must never be placed indiscriminately. UK Authorisation Number UK-2016-0998-0004
When baiting, the priority is always to exclude non-target exposure as much as possible. The product should eliminate rodents within 35 days. Do not use as a permanent bait.
For rat infestations:
Rats have an intimate knowledge of their surroundings and as a result suffer varying degrees of neophobia (they are shy of anything new). This has a detrimental effect on control. It is vital not to disturb the natural environment until control has been achieved, so avoid 'tidying up' the area before baiting. To encourage them into the bait boxes, use natural and familiar materials to protect the boxes or better still bait the burrows, whilst ensuring that potential increased risks are managed.
Use bait points of 2-3 blocks in a bait box, 10m apart, reducing to 5m in heavy infestations.
If there is no sign of activity after 7-10 days, move bait points to areas of possible higher activity.
For mice infestations:
Mice exhibit a rapid investigatory response to new objects, but their interest wanes rapidly and they move on to something new. To be successful in controlling mice you need to be proactive. Move and refresh bait points every 2-3 days.
