Thiacloprid and other neonicotinoids (e.g. imidacloprid ) have been associated with bee colony collapse worldwide. In April 2013 the EU prohibited for two years the use of several neonicotinoids on various crops due to suspected detrimental effects on bee colonies. However there is so far no evidence that use on sheep may have a detrimental effect on bees.
WARNING !!!: Never use on humans, dogs or cats.

Risk of resistance? LOW, in sheep body lice.
This means that if this product does not achieve the expected efficacy against the mentioned parasites, it is likely to be due to incorrect use and not to resistance. Incorrect use is the most frequent cause of product failure.
Imidacloprid, a neonicotinoid insecticide was introduced for the cntrol of sheep body lice control in Australia around 2010. So far there are no reports on resistance or tolerance of body lice to imidacloprid in Australia or elsewhere. Thiacloprid belongs to the same chemical class, and if resistance to imidacloprid should develop, it must be assumed that thiacloprid would show cross-resistance. Other pests have already developed resistance to imidacloprid and other neonicotinoids (e.g. houseflies) in several countries. And in the past, body lice have developed resistance to several classes of insecticides (e.g. synthetic pyrethroids, benzoylphenyl ureas) in Australia. Consequently it must be assumed that they will sooner or later develop resistance to imidacloprid as well, particularly if it is uninterruptedly used for years. To delay resistance development Integrated Pest Management (IPM) practices are a must, including product rotation with with lousicides showing mechanisms of action different from that of imidacloprid.
- Benzoylphenyl ureas (IGRs): Significant resistance problems already in Australia.
- Macrocyclic lactones (e.g. doramectin, eprinomectin, ivermectin, moxidectin, etc.) only as pour-ons or for jetting. Injectables and drenches are ineffective against most external parasites.
- Organophosphates (most organophosphates have been withdrawn from the Australian market)
These alternative products may not be available in all countries, or may not be available as pour-ons.

PIRANHA Sheep Dip Lousicice from BAYER (now ELANCO) is so far the only product containing thiacloprid approved for use in livestock in Australia.
Thiacloprid is a broad-spectrum insecticide introduced by BAYER (in the 2000s). There are so far no products containing thiacloprid approved for livestock in the USA, the EU or Latin America. Thiacloprid is abundantly used in agriculture, but not at all in livestock or pets, excepting this product. Thiacloprid is closely related to imidacloprid, another neonicotinoid abundantly used in pets against fleas. Thiacloprid does not affect ticks or mites. It has no effect whatsoever on internal parasites (roundworms, tapeworms, flukes, etc.).
