Product description: Ratzia® Blocks is a ready-to-use block bait for the control of Norway rats. For use indoors, around buildings and in sewers – the latter only by trained professional users or licensed pest controllers.
Mode of action
The active ingredient difenacoum belongs to the group of anticoagulants. It inhibits blood clotting and leads to internal bleeding. A single ingestion of a sufficient quantity may be sufficient to kill the insect; the effect usually occurs after approx. 4-10 days. The bait contains a bittering agent to reduce the risk of accidental ingestion by humans and pets. If the product is ineffective, the marketing authorization holder must be informed.
User categories
DE: For trained professional users. AT: For professional users and licensed pest controllers.
Application regulations
Before applying bait, determine the rodent species, preferred locations, cause of infestation and extent of infestation. Remove easily accessible food sources and drinking troughs. Place bait in the immediate vicinity where rodents have been observed (e.g. rodent paths, nesting sites, feeding sites, holes, burrows).
General information on placement
- Protect the bait from the weather (snow, rain) and do not place it in areas at risk of flooding.
- Replace bait if it is soiled or damaged by water.
- During inspection visits, search the area for dead rodents and dispose of them properly.
Controls and duration
At the beginning, check the baiting points at least on the 5th day and then weekly. Permanent baiting is not permitted in Austria; in Germany only possible under strict conditions (see information sheet).
Bait stations and accessibility
Bait stations must be used. A design without tamper-proof bait stations is only permitted in areas that are inaccessible to children and non-target animals (e.g. closed cable trays, cavities in walls). In Austria only permitted for licensed pest controllers without bait stations.
Special application locations
Around buildings: Do not apply the product directly into the soil (e.g. in rodent burrows or holes).
Open area: Place bait to minimize exposure to non-target animals and children. Cover/seal entrances to rodent burrows after placement to prevent entry to the surface. Collect spilled bait, bait residue and dead rodents and dispose of according to local requirements. Place bait deep into the soil and cover the area again; do not use in the rain. In Austria only permitted for licensed pest controllers.
Sewers: Apply bait in such a way that it does not come into contact with water and is not washed away. First check after 14 days, then every 2-3 weeks. In Austria only permitted for licensed pest controllers.
Application rate
Norway rats: max. 200 g per bait station, offer at a distance of 5-10 m.
