BSI Supra Bloc - Professional bait for rat and mouse control
Looking for a powerful and ready-to-use bait against rats and mice? The BSI Supra Bloc offers a highly effective solution for both domestic and professional use. This high-quality rodenticide is composed of dough-like extrusion blocks that are particularly attractive to rodents. Thanks to their structure and odor, they are quickly absorbed, leading to fast and efficient control.
The active ingredient difenacoum, a proven anticoagulant, provides a powerful action that is often superior to traditional rodenticides. Even in environments with competing food sources or with heavy infestations, Supra Bloc remains reliable and effective.
✅ Why choose BSI Supra Bloc?
- Ready-to-use bait: no preparation required, immediately deployable.
- Very attractive to rodents: thanks to the unique dough structure.
- Powerful action with diphenacoum: rapid elimination of rats and mice.
- Effective in heavy infestations: even when other food sources are present.
- Suitable for indoor and outdoor use: versatilein various situations.
🔍Application
BSI Supra Bloc is ideal for use in homes, farms, warehouses, sheds, and other places where rats and mice are a nuisance. Place the bait in secure bait boxes in strategic locations for optimal performance. In addition, the blocks are also ideal for control in humid environments.
Safety first: always place the poison in a secure bait box, so children or (domestic) animals cannot reach it!
What are extrusion blocks?
They are hard cubes of bait made via an extrusion process (similar to paste making). During that process, a mixture of grain (flour), lures, binder and a rodenticide (poison) is pressed under pressure through a mold and then cut into cubes.
What are the advantages of extrusion?
- Weatherproof: : they are much harder and more durable than cereal grains or pastes; they are less likely to weather in damp or wet conditions.
- Safe to use: :because they are sturdy and can be secured in a bait box, rats/mice can eat them but are less likely to drag them away (less risk to other animals/children).
- Long-lasting effect: they remain attractive and effective longer, even outside or in damp areas (stables, basements, outdoor areas).
- Selective uptake: because they crumble less, non-target animals are less likely to pick up small scraps.
- Convenient in control: because they remain in solid form, you can quickly tell if they have been eaten.
