Fleas & Ticks
Fleas attack a wide variety of warm-blooded vertebrates including dogs, humans, chickens, rabbits, squirrels, rats and mice. Fleas are a nuisance to their hosts, causing an itching sensation which in turn may result in the host attempting to remove the pest by biting, pecking, scratching etc the vicinity of the parasite. Fleas are not simply a source of annoyance, however. Some people and animals suffer allergic reactions to flea saliva resulting in rashes. Flea bites generally result in the formation of a slightly-raised swollen itching spot with a single puncture point at the center. The bites often appear in clusters or lines, and can remain itchy and inflamed for up to several weeks afterwards. Fleas can also lead to hair loss as a result of frequent scratching and biting by the animal, and can cause anemia in extreme cases.
Ticks are often found near wooded and highly vegetated areas. Some species require moisture to survive. All females and males of most species feed on blood of mammals, birds and reptiles. There are four stages in a tick’s lifecycle – egg, larvae, nymph and adult. Ticks have only six legs during their larval stage and eight legs during their nymphal and adult stages. They consume blood meals during all stages. Pathogens, or organisms that cause diseases in the animals they infect, can be passed through the stages of a tick’s life cycle. Ticks not only cause irritation and discomfort, but they also are capable of transmitting serious diseases to humans and other animals.
