RESISTANCE PREVENTION

Risk of resistance? YES, moderate in:

There are reports on resistance of fleas and brown dog ticks (Rhipicephalus sanguineus) to carbamates, with cross-resistance to organophosphates. For this reason efficacy and protection provided by this product against these parasites may be lower or shorter than expected.

So far there are no reports on resistance of fleas to methoprene, but this compound does not kill fleas, it only inhibits their development, and it has no effect whatsoever on ticks.

Alternatives to prevent resistance through product rotation:

*F = effective against fleas; T = effective against ticks.

These alternative products may not be available in all countries, or may not be available as collars.

Resistance of fleas and brown dog ticks to pyrethroids is not uncommon in several countries, including the USA.

COMMENTS

POWERBAND is a veteran insecticide-impregnated collar for dogs from VET-KEM containing generic active ingredientsPropoxur is a carbamate effective against fleas and ticks, broadly used in topical products for pets (shampoos, soaps, sprays, powders, etc.) and in crop pesticides. Methoprene (= (S)-methoprene) is an Insect Growth Regulator that does not kill fleas but inhibits their development. It has no effect on ticks. It is also broadly used on pets and agriculture.

According to the label this product provides up to 5 months control of fleas and ticks, but efficacy may be lower and protection shorter than expected in case of resistance. The tick species controlled are not specified in the label.

VET-KEM markets a collar for cats with exactly the same active ingredients under the TM BREAKAWAY PLUS.

Topical products (mainly spot-ons and insecticide-impregnated collars) have some advantages over systemic products (mainly tablets for oral administration and injectables):

  • Most topical products kill or sterilize the parasites before they bite and suck blood on the pet, whereas systemic products kill or sterilize the parasites only after their blood meal.
  • Topical products cannot be vomited.
  • Spot-ons and collars are very convenient to administer.
  • There is a larger choice of topical products.

But topical products have also some disadvantages:

  • Topical products contaminate the pet's hair coat and it is advisable for children and also adults to avoid contact with the pet for several days after treatment.
  • Topical products may not control parasites in some parts of the pet's body (e.g. the ears, below the tail, between the legs, etc.), whereas systemic products reach the blood-sucking parasites through the blood wherever they are.
  • Efficacy of topical products may be reduced or shortened through exposure to dirt, sun, shampooing, washing, rain, baths, etc., whereas efficacy of systemic products is independent from these factors.
