Evicto Spot-On by Virbac is a monthly topical treatment for medium dogs weighing 10–20kg. It uses selamectin as its active ingredient to protect against fleas, worms, mites, lice, and heartworm disease.

Selamectin provides ovicidal activity against fleas, disrupting the life cycle rather than just killing adult fleas on contact. The formulation also covers roundworm, hookworm, and heartworm prevention in a single monthly application. Tubes are transparent for easy dose confirmation, and the low-volume formula is designed to be non-greasy and fast-drying. Safe for use from six weeks of age.

Evicto suits owners who want broad-spectrum parasite coverage without managing multiple products. The selamectin-based formula has an established veterinary track record, and the monthly dosing schedule keeps compliance straightforward.
