Risk of resistance? YES.
There are no reports yet on resistance of body lice Bovicola (Damalinia) ovis to ivermectin. However, there are reports indicating cross-resistance with ivermectin in Lucilia cuprina diazinon and/or Diflubenzuron resistant strains, although the resistance factors were low (2-3x). A ten-fold resistance to ivermectin was also achieved after laboratory selection of a Lucilia cuprina field strain over 30 generations. This strongly indicates that Lucilia cuprina field populations may develop resistance to ivermectin if submitted to sustained selection pressure with ivermectin.
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.
- Neonicotinoids (e.g. imidacloprid). No efficacy against blowfly strike.
- Spinosad. Short protection periods.
These alternative products may not be available in all countries, or may not be available for jetting.

JETGARD BLOWFLY & LICE JETTING FLUID is a lousicide and blowfly strike preventative from HUNTER RIVER COMPANY containing generic ivermectin.
Ivermectin is the parasiticide for livestock and pets most widely used worldwide, with hundreds if not thousands of generic brands. It was introduced in the early 1980s (by MS&D AgVet). Ivermectin is probably the best veterinary parasiticide ever developed, highly effective against roundworms as well as against numerous external parasites (ticks, flies, lice, mites, etc.), but not against tapeworms and flukes. Twelve weeks protection against blowfly strike is not outstanding compared with other products available against this parasite that may reach up to 24 weeks protection.
