To continue the interesting theme I started a few days ago, speaking on how insects can affect our pets, and for today's topic, I will be picking flies and analyzing if they hurt our pets or not. Flies are winged insects that belong to a large, complex order of insects called Diptera. There are different types of flies and they are different in terms of development, habitats, size, and even their preference for food. An adult fly for instance, may prefer to feed on saliva, blood, mucus, and tears. Flies are more than just an annoyance we want to get rid of, they can also spread diseases and problems in our pets.
