The main clinical signs/symptoms of equine helminth infections are weakness, rugged hair coat, slow growth, cramps and diarrhea. Refer to the manufacturer’s label for directions for use and cautions for trichlorfon. They are prone to Gasterophilus infections because the pastures where they graze are contaminated with infective stages (eggs and larvae) of Gasterophilus, resulting in continuous infestation and re-infestation. Strongyloides westeri is an intestinal threadworm commonly infecting young foals, and it has been associated with small intestinal enteritis, resulting in diarrhea.The pathogenicity of the parasite remains unclear, however.
A key to the eggs of the equid stomach bot flies is presented.

Myiasis is defined as a condition in which maggots are from certain fly species that utilize living, dead, or necrotic tissue from the host as a feed source for their growth and development and attack all types of vertebrate animals that are warm-blooded including humans. Since the early 1900s until presently (2015), more than 25 products have become commercially avail-able for control of endoparasites in horses.

Organophosphorus systemics for treating warbles were intended for application in the autumn when the entire population is in the larval stage and before the larvae have reached the hide. The presence in some regions of southern Europe of an unusually large number of different species of bot fly suggests a high degree of oestrid biodiversity in this area. The horse botfly (Gasterophilus spp.) may cause restlessness and stamping as the flies hover and lay eggs on the hair of the horse's lower limbs and head.Dermatobia hominis, the human botfly, may infest horses in Central and South America.
