Please sign-in to view pricing and order products.

Harmonix® Rodent Paste is an innovative rodenticide bait that offers several unique advantages for professional users. The product contains the active substance cholecalciferol which has a different mode of action to the predominantly used anticoagulant rodenticides.

Contains: Cholecalciferol 0.075%

Controls: Rats & Mice

Application: Indoors and outdoors (around buildings), burrows, waste dumps and open areas.

Availability: In stock

Harmonix® Rodent Paste is based on the non-anticoagulant rodenticide cholecalciferol, at 0.075%, presented as an optimised paste bait matrix formulation. Cholecalciferol is effective against anticoagulant-resistant Norway rats and house mice. It is not bioaccumulative or persistent and therefore presents relatively lower secondary poisoning risks to non-target species, such as birds of prey, compared to second generation anticoagulants. Areas and types of use for Harmonix® Rodent Paste are indoors and outdoors around buildings, open areas, waste dumps, burrow baiting, permanent baiting, tamper-resistant bait stations and in covered and protected baiting points. Also available is the non-toxic Harmonix® Monitoring Bait as a complementary monitoring option – matching the monitoring product to the rodenticide that may be subsequently employed.

The non-toxic monitoring bait, called Harmonix® Monitoring Paste, has a very similar bait matrix to Harmonix® Rodent Paste. When bait takes of the monitoring product indicate rodent activity, the change to the cholecalciferol product can be made swiftly. This process, of complementary monitoring then switching to cholecalciferol, can help judge the level of initial activity, overcome bait shyness, improve initial bait consumption, shorten the baiting time and therefore reduce the length of time that rodenticides are in place. The kind of complementary monitoring, matching the monitoring product to the rodenticide, is part of a ‘dynamic IPM’ plan as termed by Bayer.

Harmonix® Rodent Paste has a wide application allowance on the label, covering burrow baiting, open areas and waste dumps. Burrow baiting can avoid neophobic response and improve bait uptake. Applying bait directly into the burrow system removes the likelihood of rodents finding additional food sources

Follow-up visits are different to anticoagulants and bait points should therefore be visited at least every 1 to 2 days at the beginning of the treatment and at least weekly afterwards, if not applied as part of a permanent baiting programme.

To be used in tamper resistant bait stations such as: Rotech NG Mouse Box, Rotech Vanguard Rat Box, Rotech Bullet Rat Box
