In order to prevent an infestation, it is advisable to avoid densely wooded areas because these can be common habits for ticks. If your pets are commonly in wooded areas, it is wise to invest in anti-tick medication for pets. If your pet constantly scratches, shows signs of a skin irritation or becomes lethargic, you may have a tick infestation. If you do believe that your pet may have a tick problem, contact your vet for the best method to get rid of them. Because ticks can spread, you should also check your home for the pests. Ticks prefer to live in dry, warm places near their hosts, such as bedding and furniture.
