Methods and formulations for treating animal ectoparasites, effective against parasites such as fleas and ticks are provided. The methods comprise topically co-administering a non-mobile insect growth regulator, a mobile insect growth regulator, and an adulticide to the animal. Parasiticidal formulations for treating animal ectoparasites are also provided, which can be safe to use and avoids the many common deleterious side effects of conventional topical formulations. The topical formulations comprise a combination of two insect growth regulators and an additional insecticide. The topical formulation can be packaged together or packaged so that active components are stored separately prior to administering the topical insecticide formulation to the animal.

Animal parasite-control method using insect growth regulators

Methods and formulations for treating animal ectoparasites, effective against parasites such as fleas and ticks are provided. The methods comprise topically co-administering a non-mobile insect growth regulator and a mobile insect growth regulator to the animal. Parasiticidal formulations for treating animal ectoparasites are also provided, which can be safe to use and avoid the many common deleterious side effects of conventional topical formulations. The topical formulations comprise a combination of two insect growth regulators, a non-mobile insect growth regulator and a mobile insect growth regulator. The topical formulation can be packaged with the two insect growth regulators together or packaged to prevent mixing of the two insect growth regulators prior to administering the topical insecticide formulation to the animal.

An applicator tip is provided for operating in conjunction with a pierceable fluid reservoir. Assemblies in accordance with the invention can lead to an exceptionally easy to use, safe, and convenient system and method of applying a fixed dosage of chemicals to which a user might wish to avoid contact, such as parasiticides. The cap-applicator can have an internal piercing tip capable of piercing the reservoir when the assembly is converted into an active configuration. Projections can be provided, in the form of fins on a tube or a multi-prong structure with straight or curved projections. The tips of one or more projections can include dispensing ports or the ports can be recessed from the distal tip, such as in a notch, so as not to be obstructed if the distal tip of the cap is pressed against an animal to dispense the fluid.
