Leila’s three horses mainly live out on 4.5 acres of grazing that is poo-picked daily. Each is wormed for encysted redworm and tapeworm and has a regular faecal egg count, so it surprised Leila ...

If you suspect your horse is suffering from pinworm, eggs can be collected from skin around the tail area on a piece of cellophane tape, which can then be examined under a microscope.

A pinworm or threadworm infection happens when eggs transfer from the anus or contaminated surfaces to the mouth and intestine. It causes itching. Treatment is available.
