Deltamethrin for the prevention of nuisance fly and control of biting and sucking lice


Each 1 Liter contains 15 g Deltamethrin.


Use Vetmed Delmax Pour-On when nuisance flies are first seen in the shed (usually late spring).

Treat early to prevent the fly population from building, and every month while conditions for flies are favourable. Delmax Pour-On is a water based synthetic pyrethroid insecticide for control of biting and sucking lice (Bovicola bovis, Linognathus vituli, Haematopinus eurysternus and Solenopotes capillatus) on cattle of any age. It also controls nuisance fly (Stomoxys calcitrans) for a period of up to four weeks. Maximum lice kill is achieved up to six weeks after application, though relief of symptoms is rapid. DO NOT apply Delmax Pour-On to wet cattle. Do not use if rainfall is pending. Delmax Pour-On is a non-systemic. It controls lice by dispersing externally around the body of the animal; therefore accurate application is critical.

Direction for use:

Shake well. Apply using a Vetmed T-Bar Gun. Must be applied in a wide (5 to 10cm) continuous strip from between the ears to the tail, down the midline, to ensure even dispersion of product down both sides of the animal. Dose according to the heaviest animal, see below dose rate table. Clean equipment thoroughly after use.

Withdrawal period:

Meat: 28 Days

Calves: No withholding period is required prior to slaughter for calves born to cows treated in late pregnancy and then allowed to suckle those cows. MILK: NIL
