TickHex® Body SprayTicks and fleas are not a minor nuisance. Ticks carry serious tick borne diseases, such as Lyme disease, tick paralysis, and they are hungry! Fleas can also be a nuisance, causing skin disease, allergies and infesting our pets with tapeworm. For ticks, spray TickHex on your dogs coat before walks during peak season to repel them. For fleas, use spray once a week or more frequently in cases of severe infestation.
