Here is my post from 2017 but you need to speak to your vet because they may have better treatment now:

The general consensus now is that Panacur Guard 5 day wormer is the best one to use followed four to six weeks later by another wormer with the right chemical in it - Pyrantel Embonate (found in Strongid P and Pyratape P). These pinworms are becoming more and more prevalent and vets are only now waking up as to how to deal with them.

The pinworms live inside the rear end of the horse. They come out when the horse is resting, normally at night, and lay their eggs around the anus. You might see a sticky substance containing the eggs deposited by them around the anus. The eggs drop off into the bedding and pasture or by being rubbed onto stable walls and fences. Horses carrying these worms will often scratch themselves to the point of making sores which can get infected. But not all horses scratch. They can be a complete nightmare to get rid of and can take up to 18 months to 2 years to eradicate. This is because you need to break the cycle of the horse ingesting the eggs and then breeding again. The eggs can remain viable outside the body for about 6 to 10 weeks.
Ingested eggs hatch in the small intestine releasing the L3 larvae that penetrate into the mucosa. About a week later they molt to L4-larvae that attach to the mucosa of the ventral colon. About 2 months later they complete development to adult worms. Sexual maturity is reached 3-4 months later.

The time between infection and first eggs shed (prepatent period) is 4-6 months, although there are reports suggesting that it may be shorter based on the observation of foals not older than 3.5 months that already carried Oxyuris egg masses in the perianal region.

It appears that normal wormers are ineffective because they are absorbed before they get to the worms in the hindgut. The only success most owners report is using 5 day panacur guard combined with the use of Neem Oil. You can buy organic Neem Oil cheaply on Ebay. You need to paint the Neem Oil on every day, preferable twice, but more importantly at night. This oil prevents the eggs from sticking and also is a powerful insecticide which harms the worms if they touch it. Some people say that it also interferes with the hormones of the worms - not sure about that though. Some owners have also used syringed wormers by inserting them in the anus but some vets say that this does not work.

It is advisable to disinfect the stable, (walls and destroy bedding) tack and the grooming kit.
Apart from being ugly and creepy they don't actually harm the horse unless, of course, the horse is causing sores from scratching.

My youngsters had pin worms in May. HHO users recommended a programme of Panacur Guard 5. That is not available in Ireland so got Panacur 10% from my vet and dosed for five days and that sorted them right out.
