Description
Lodi Gems Harmonix Rodent Paste 5kg
Lodi Gems Harmonix Rodent Paste is a ready-to-use, non-anticoagulant rodenticide for the control of rats and mice in agricultural and other approved environments. Containing 0.077% w/w cholecalciferol (Vitamin D3) as its active substance, Harmonix works differently from traditional anticoagulant rodenticides and is designed to provide effective rodent control while using less bait.
Harmonix is supplied in convenient 20g pre-baited paste sachets, formulated with fats and oils to provide a highly attractive bait for rats and mice. The sachets can be placed directly into suitable bait stations, reducing handling of the rodenticide and making application straightforward.
Harmonix has a Stop Feed effect, with rodent feeding reduced after approximately 2–3 days and control achieved in as little as 7 days. Its non-anticoagulant mode of action also means there is no known resistance build-up, making it a useful option where resistance to anticoagulant rodenticides is a concern.

Attractive 20g Paste Sachets
Gems Harmonix is supplied as individual 20g paste sachets, providing a convenient ready-to-use bait format. The paste contains fats and oils that help make it attractive to rats and mice, encouraging feeding when placed in areas of known rodent activity.
The sachets can be used directly in appropriate bait stations, helping to minimise handling and keeping the bait contained. Do not open or tear the sachets unless specifically instructed by the product label.
Reduced Secondary Poisoning Risk
One of the advantages of Harmonix is its cholecalciferol-based, non-anticoagulant formulation. Cholecalciferol is not bioaccumulative or persistent, meaning Harmonix presents a lower risk of secondary poisoning to non-target species, including birds of prey, compared with second-generation anticoagulant rodenticides (SGARs).
This does not mean there is no risk of secondary poisoning. Dead rodents should be searched for and removed regularly in accordance with the product label to help minimise the risk to non-target wildlife.

Use & Application
Gems Harmonix should be used strictly in accordance with the current Irish product label. It is approved for use against rats and mice in specified agricultural and other permitted situations, including approved indoor and outdoor applications.
Place the 20g sachets securely in suitable bait stations or other locations permitted by the product label, positioned where rodent activity has been identified and where access by children, livestock, pets and other non-target animals can be prevented.
Regular monitoring is an important part of an effective rodent control programme. Bait points should be inspected regularly and rodent activity assessed throughout the treatment period. Any dead rodents found should be collected and disposed of safely in accordance with the label instructions.
Always read the product label and follow all instructions and precautions before use. Use rodenticides responsibly as part of an integrated rodent management programme.
Ideal For
Gems Harmonix Rodent Paste is particularly suitable for agricultural rodent control in and around:
- Dairy and livestock farms
- Poultry units
- Pig units
- Farm buildings
- Agricultural storage areas
- Feed storage areas
- Approved outdoor areas around buildings
Its non-anticoagulant formulation makes Harmonix a useful alternative where resistance to conventional anticoagulant rodenticides is a concern, while its lower secondary poisoning risk compared with SGARs can be an important consideration when managing rodent populations around agricultural environments.
