Elanco Demize POUR-ON FOR CATTLE - 5L Backpack

Demize™ is a fast and easy way to control all four major species of synthetic pyrethroid-susceptible cattle biting and sucking lice, buffalo fly, house fly and stable fly in a convenient, pour-on formulation that doesn't bead, drip or run.

Demize Pour-On is registered for the control of biting and sucking cattle lice (Bovicola bovis, Haematopinus eurysternus, Solenopotes capillatus and Linognathus vituli), House fly (Musca domestica), Stable fly (Stomoxys calcitrans), and synthetic pyrethroid susceptible Buffalo fly (Haematobia irritans exigua) on cattle.


  • Controls all four major types of cattle lice
  • Controls House fly, Stable fly and SP-susceptible Buffalo fly
  • Rainfast pour-on formulation
  • Special applicator produces even band down backline
  • Upright 5 L back-pack minimises operator exposure
  • Less risk to humans than OP compounds



Demize controls all four of the major species of biting and sucking lice found in Australia. Field trials conducted throughout southern Australia have demonstrated that Demize provided equivalent or superior lice control compared to deltamethrin, the active ingredient in a commonly-used parasiticide.

Demize eradicated Biting lice (B. bovis) in 5/5 trials and Short-nosed sucking lice (H. eurysternus) in 3/5 trials. Demize provided better control of Long-nosed sucking lice (Linognathus vituli) in 4/5 trials (P<0.1) and was significantly more effective than deltamethrin against Small blue sucking lice (Solenopotes capillatus) in 1/2 trials (P<0.05).


Demize protects cattle from irritation by significantly reducing the size of Stable fly and House fly populations. In one small pen study, Demize reduced the number of flies infesting treated cattle by more than 80% four days after application.

A field efficacy trial demonstrated Demize was at least 89% effective seven days after treatment and at least 73% effective 11 days after treatment. By comparison, deltamethrin was at least 81% and 65% effective seven days and 11 days after treatment. Efficacy was calculated as the percentage reduction in fly numbers compared to fly numbers three days before treatment.

Demize also provides excellent control of SP-susceptible populations of Buffalo fly. Field trials conducted in Queensland demonstrated Demize achieved more than 95% efficacy against Buffalo flies for three to 14 days after application, depending on the resistance status of the local fly population. Heavy rainfall occurring immediately after treatment had no adverse impact on efficacy.
