Yard Spray Concentrate by Virbac is an insecticide concentrate used for use on outdoor surfaces in order to prevent tick and flea infestations.


Yard Spray Concentrate kills fleas and ticks on the outdoor surfaces, such as lawns or backyards. It is one of the means to prevent external parasite infestations in animals, along with topical products.


Fleas are the parasitic insects that attack humans and animals in order to feed with their blood. Fleas are very fertile; within only one day of their first blood meal on the host, they lay numerous eggs. Their life cycle is completed in four stages, when they develop into adults. The entire cycle lasts for only two to three weeks. Fleas are barely visible by the naked eye, but they move around very quick and are very difficult to detect. In order to suck blood, fleas have to bite and chew through the animal’s skin. Those actions cause a great deal of discomfort for the animal. As a result of severe itch, the animals are biting and scratching the affected areas of the skin, causing the visible irritation with redness, swelling and crusts. Flea feces are usually visible as small black dots between the hairs. It is often – besides the itch – the only visible sign of flea infestation in animals.

Ticks are spider-like parasites that survive by feeding on blood of humans and animals. Their life cycle has four stages. Adults attach themselves onto the skin of an animal or a human and start sucking blood. Ticks are visible between the hairs, especially after they have fed since they grow in size as they feed. Ticks usually cause mild local irritation of the skin around the attachment area. However, in severely infested animals ticks can cause anemia. Young and debilitated animals are especially sensitive to complications of tick infestations.


Flea bites are often associated with allergic reactions and severe skin infections. In young and debilitated animals, fleas can cause anemia. They are the transmitters of tapeworms.

Tick bites cause anemia and allergic reactions in certain cases. Their main significance lies in the potential to transmit various viral, parasitic and bacterial diseases, such as Lyme disease, Babesiosis, Lyme disease or Ehrlichiosis.


Animals of all breeds are susceptible to external parasite infestations.
