RECOMMENDED DOSE & USE INSTRUCTIONS

CATTLE AND HORSES

For control of Cattle Tick, New Zealand Cattle Tick and Paralysis Tick

  • Use as a plunge dip, recirculating spray race, constant replenishment spray race or hand spray at a dilution rate of 1:1000 (1 litre product per 1000 litres of water) = 75 ppm = 75 mg flumethrin per litre of wash. When spraying, use a minimum of 8 - 10 litres of wash per adult to ensure saturation. Repeat treatment at intervals no more than 19 - 21 days as part of strategic tick control program. However for Paralysis tick and NZ Cattle tick, treat every 10 days from first appearance of ticks. 

DOGS:

For control of Brown Dog Tick and New Zealand Cattle Tick

  • Use as a wash with a dilution rate of 3 mL product to 5L water. The dog must be thoroughly wet with the rinse all over by using a sponge to rub the wash into all parts of the coat. Do not wash out, allow to dry in the coat. Repeat fortnightly for continuous control.

Bayticol Dip and Spray is effective against sensitive strains of cattle tick but resistance may develop to any tickicide. If lowered level of control is experienced, resistance testing of your ticks is recommended.


SAFETY

  • LD50 (acute oral) in rats: >500-<1000 mg/kg (of formulation, according to MSDS)
    LD50 (acute dermal) in rats: >5000 mg/kg (of formulation, according to MSDS)
  • Estimated hazard class according to the WHO: II, moderately hazardous

Suspected poisoning? Read the article on flumethrin safety in this site.

Withholding periods (=withdrawal times) in days for meat & milk (country-specific differences may apply: read the product label)

  • Meat
    • Cattle: AUS NIL (0 days)
    • Horses: AUS 1 day
  • Milk for human consumption: AUS NIL (0 days) 

WARNING !!!: Never use on humans or cats. Synthetic pyrethroids are toxic to cats!

Flumethrin and all synthetic pyrethroids (e.g. cyhalothrin, cypermethrin, deltamethrin, etc.) are extremely toxic to fish and aquatic invertebrates. Do not contaminate dams, streams or waterways with product or used containers. Store original container, tightly closed in a safe place under lock and key.


RESISTANCE PREVENTION

Risk of resistance? YES, resistance of cattle ticks (Rhipicephalus = Boophilus microplus) to all synthetic pyrethroids (incl. flumethrin) is widespread in AUS and elsewhere and can be very high. 

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, although this is usually the most frequent cause of product failure.

Alternative chemical classes/active ingredients to prevent resistance of external parasites through product rotation:

These alternative products may not be available in all countries, or may not be available for dipping or spraying, or may not be effective against all the concerned parasites.

COMMENTS

Flumethrin is a synthetic pyrethroid introduced by BAYER in the 1970s. It is probably the best synthetic pyrethroid against ticks, but less effective against biting flies than other synthetic pyrethroids (e.g. cypermethrin, deltamethrin, etc.). Flumethrin is also available as a pour-ons in many countries, but the pour-on formulation was withdrawn from the Australian market in the early 2002's because of potential issues with flumethrin residues in beef for export to the USA.

Until cattle tick resistance to flumethrin became widespread BAYTICOL was probably the world leading tickicide for cattle. Nowadays it remains a very appreciated product where resistance of cattle tick is not an issue.

Insecticide concentrates for spraying and dipping such as this product often represent the cheapest option for insect control on animals. However the active ingredients used in such products are mostly rather old (introduced in the 1950s to 1970s) and many pests have developed resistance to them. More modern and often more effective active ingredients for the control of external parasites are often not available as concentrates but only as ready-to-use pour-ons, injectables, or in the form of insecticide-impregnated ear-tags. They are often more effective, more convenient and with a longer protection period than the concentrates, but are also more expensive and often not approved for the control of as many pests as the concentrates.

All synthetic pyrethroids are veteran pesticides developed in the 1970s-1980s and are basically contact insecticides. This means that when the parasite comes in contact with it (e.g. during the blood meal, after landing on a treated host, etc), the active ingredient that impregnates the host's hair coat penetrates through the cuticle (i.e. the "skin" of insects and other arthropods) into its organism and disturbs essential biological processes in the parasite's body, in this case its nervous system.

After administration to livestock or other animals, synthetic pyrethroids do not have a systemic mode of action, i.e. they are not transmitted to the parasite through the blood or the host. Topically administered synthetic pyrethroids are very poorly absorbed through the skin of the hosts, and what is absorbed is quickly broken down and/or excreted. Consequently the concentration reached in the blood is too low to kill blood-sucking parasites. But this is why they are considered rather safe for mammals, both humans and livestock (cats are an exception: pyrethroids are toxic to them!) and why they leave rather low residues in meat and milk.

For best results it is very important to ensure a complete coverage of the animals' hair coat (depending on hair coat adult cattle may need 3 to up to 10 liters product for complete wetting). This is best achieved after dipping the animals. Best alternative to dipping are spray races. Efficacy after hand spraying is often poor due to the fact that using these methods some parts of the body may not be properly treated (e.g. inside the ears, below the tail, the udders, etc.), which allows a significant number of parasites to survive, reproduce and perpetuate the infestations. To learn more about correctly dipping or spraying cattle and other livestock read the corresponding articles on dipping and spraying livestock in this site.

It is useful to know that the active ingredients of many synthetic pyrethroids consist in a mixture of various optical isomers, typically those called "cis", and those called "trans". Flumethrin also consists of a mixture of various optic isomers, but all commercial products contain the same mixture, i.e. this makes no difference in the product quality or efficacy.
