D-Block
Control rats either indoors or outdoors with hard block baits.
's active ingredient is Diphacinone – a first-generation anticoagulant. The low risk of secondary poisoning from first-generation anticoagulants makes them a great choice for farm situations and the environmentally conscious.
Use in bait stations for rats like our Run Through, Zig Zag, and Tunnel stations.

- Diphacinone – 0.05g/kg Features
- Small and lightweight – each block weighs 28 grams
- Use indoors or outdoors – in bait stations
- Super tasty – rats prefer fresh grains and nuts to wax (we've sacrificed a longer shelf life to achieve this)
- Low risk of secondary poisoning – its short half-life compares favourably to other toxins
- Prevents target animals hiding and storing bait (bait caching) – each block has a hole which lets you secure it onto internal bait station spikes (or wire, nail or tie in place)
- Used by experts – the Department of Conservation and other leading conservationists and pest controllers
- Antidote is readily available – Vitamin K
- No Controlled Substance Licence (CSL) required
how long a substance takes to reduce its concentration by half Environmental impact
- Breaks down a lot faster than other toxins – its half-life in tissue and blood is only 3 days. Brodifacoum, the most commonly used second-generation anticoagulant, is 130-300 days.
- Minimal risk of secondary poisoning
- Minimal risk to native birds and non-target species Safety for handlers
- Use according to the Safety Data Sheet How to use hard blocks
