Fleas are a distressing pest that are normally associated with domestic properties. However, they can occasionally be transported, on clothing, to the office and other working environments.
Provided the problem is caught early, it can usually be dealt with easily with one treatment with a liquid pesticide. More established flea infestations may require multiple treatments.
To avoid flea infestation on both cats and dogs, use an appropriate, vet provided, preventative treatment on your animals.
