Risk of resistance? YES
Resistance of blowfly strike has been reported both in Australia and New Zealand. In Australia it is that high, that triflumuron and other benzoylureas are no more approved for blowfly strike control. For this reason efficacy of this product against sheep blowfly strike may not achieve the label claims. This means that if this product does not achieve the expected efficacy against the mentioned parasites, it may be due to resistance and not to incorrect use, which is usually the most frequent cause of product failure.
- Macrocyclic lactones (mainly ivermectin)
- Neonicotinoids (e.g. imidacloprid). No efficacy against blowfly strike.
- Spinosad. Short protection periods.
- Synthetic pyrethroids (e.g. cypermethrin): resistance of body lice present in New Zealand.
These alternative products may not be available in all countries, or may not be available for jetting.

ZAPP JETTING LIQUID for sheep is a brand from BAYER with original triflumuron.
Triflumuron is a broad-spectrum insect growth regulator (IGR) belonging to the benzoylphenyl-ureas introduced in the 1980s (by BAYER). It is effective against immature stages (larvae, nymphs, etc.) of numerous insects but not against adult stages. It is scarcely used in sheep and horses but only in Australia and New Zealand, not in Europe or the US. It is not used so far in other livestock or in pets. It is also used moderately against agricultural and household pests.
It is important to understand that this and other products containing insect growth regulators do not kill adult lice that may infect sheep at the moment of treatment, i.e. they don't have a knock-down effect. What they do is to interrupt further development of immature stages. Larvae and/or nymphs fail to molt to the next stage and die. Therefore they are used to prevent the further development of immature stages or eggs of occasional adult lice that sheep may catch.
Triflumuron and other benzoylphenyl ureas conquered the sheep body lice market very quickly in Australia and New Zealand after resistance to synthetic pyrethroids exploded and organophosphates that still worked well were progressively withdrawn for safety reasons.
It is interesting to know that neither triflumuron nor other benzoylphenyl ureas are used on sheep in the EU, the US or in Latin America, where body lice is also an important pest of sheep. The likely reason is that organophosphates and/or synthetic pyrethroids are still widely used in these countries against this pest that has not yet become resistant to these chemicals there.
