Regular flea and heartworm treatment is important all year round in the temperate climate of Florida.  Fleas are not only a nuisance to your pet by causing itching, possible hair loss and infestation of your home, but if ingested can cause tapeworms.  Heartworms are transmitted to pets by mosquitoes.  The prevention is extremely affordable, ranging from $4.00 - $8.00 per month, especially in comparison to treating heartworm disease, which can be in the hundreds of dollars.
