Houseflies, or Garbage Flies, gravitate towards and lay their eggs on decaying organic material. Their habits make them incredibly unsanitary, especially in large numbers. If a fly lands on utensils or food, consuming the bacteria can cause serious problems such as food poisoning, meningitis, diarrhea and infections. Because of their small wings, flies land often and can deposit thousands of bacteria each time then do.
Fleas are wingless parasites specially adapted for piercing skin and sucking blood. They attach a wide variety of creatures including humans, cats, dogs, rabbits, and squirrels. While fleas are known to feed on humans, they prefer hairy animals such as dogs and cats. Not only are they a source of annoyance, but they can cause rashes and/or impotence.Female fleas lay eggs on a host or on the ground; the eggs may then drop from the host and infest carpets, bedding and furniture. Flea bites may manifest as clusters or lines of two bites and can remain itchy for several weeks after a host has been bitten. Multiple treatments are often needed to get rid of a flea population. Getting rid of fleas on a pet is not enough to eradicate them completely.
