In particular this invention provides for spot-on compositions for the treatment or prophylaxis of parasite infestations in mammals or birds which comprise: The invention also provides for a method of treating parasitic infestations or for the prophylaxis of parasite infestations in mammals or birds which comprises topically applying to said mammal treating parasitic infestations or for the prophylaxis of parasite infestations in mammals or birds which comprises topically applying to said mammal or bird an effective amount of a composition according to the present invention.

Spot-on formulations for combating parasites

Direct spot-on antiparasitic skin solution for domestic animals

Method for eradicating fleas in domestic or accommodation premises of a domestic or laboratory mammal is provided. The method involves topically applying, at least monthly, to the domestic or laboratory mammal, a parasitically effective amount of compound of Formula I.

Process and means for the eradication of fleas in the habitats of small mammals

Process and composition, in particular for controlling fleas on small mammals, characterized in that the composition includes, on the one hand, at least one insecticide of 1-N-arylpyrazole type, in particular fipronil, and, on the other hand, at least one compound of IGR (insect growth regulator) type, in doses and proportions which are parasiticidally effective on fleas, in a fluid vehicle which is acceptable for the animal and convenient for local application to the skin, preferably localized over a small surface area.

Insecticidal combination to control mammal fleas, in particular fleas on cats and dogs

The invention concerns a method and a composition against parasites and particularly ectoparasites and, preferably also endoparasites of small mammals and in particular dogs and cats. The composition contains a compound (A) of formula (I) and a compound (B) consisting of an endectoparasiticide of the macrocylic lactone type.

Parasiticidal combination

Direct pour-on antiparasitic skin solution and methods for treating, preventing and controlling myasis

Processes for the antiparasitic control of darkling beetles utilizing 1-arylpyrazole insecticides and for applying said insecticides to animal litter, especially for animal rearing, are described. Also described are mixtures of carbaryl and 1-arylpyrazole insecticides.

Process and composition for the antiparasitic treatment of the surroundings of animals

Methods for removing parasites and in particular ectoparasites of vertebrates, in particular of mammals, and compositions for the implementation of this method. Methods for removing parasites of vertebrates, and in particular arthropods, mainly insects and Arachnida, wherein an effectively parasiticidal amount of a compound of formula (I) ##STR1## in particular of fipronil, is administered to the animal via an administration route which makes possible systemic distribution and good absorption.

Method for removing parasites and in particular ectoparasites of

Insecticidal combination to control mammal fleas, in particular fleas on

Collar or other external device for a pet, in particular a cat or dog, made of a matrix in which is incorporated from 0.1 to 40% by weight, preferably from 1 to 15% by weight, relative to the collar, of a substance which is active against ectoparasites such as fleas and ticks, this active substance being formed of at least one compound corresponding to formula (I) below: ##STR1## this collar or other external device being designed to ensure more than 6 months of efficacy against fleas and more than 3 months of efficacy against ticks, the efficacy being maintained for several weeks even if the collar or other external device is taken off or lost or if there is a variation in the release of the compound.

N-phenylpyrazole-based anti-flea and anti-tick collar for cats and dogs

Method for fighting against myiasis affecting cattle and sheep

Collar or other external device for a pet, in particular a cat or dog, made of a matrix in which is incorporated from 0.1 to 40% by weight, preferably from 1 to 15 % by weight, relative to the external device, of a substance which is active against ectoparasites such as fleas and ticks, this active substance being formed of at least one compound corresponding to formula (I) below: ##STR1## this collar or other external device being designed to ensure more than 6 months of efficacy against fleas and more than 3 months of efficacy against ticks, the efficacy being maintained for several weeks even if the collar or other external device is taken off or lost or if there is a variation in the release of the compound.

N-phenylpyrazole-based anti-flea and anti-tick external device for cats

The external device such as a ring, in particular an ear-ring, intended to eliminate cattle parasites, in particular Haematobia irritans, formed of a matrix including from 0.1 to 40%, preferably from 2.5 to 10%, by weight, relative to the ear-ring, of an active substance which is at least one compound of formula (I) below: ##STR1## this external device being designed to ensure efficacy for more than 30 weeks.
