Worming Information

Fecal Examination:
Fecal egg counts should be done on a yearly basis to monitor effectiveness of your current parasite control program.
For horses under the age of 1 year old and for horses with a suspected high worm load consult your veterinarian as adverse reactions could occur.  
 
Ivermectin (Eqvalan):  
Kills most internal parasites in a single dose. It is the cornerstone of most conventional worming programs. It is also effective against external parasites such as ticks and sucking lice.
Used in the late winter or early spring.
 
Moxidectin/Praziquantel (Quest Plus):
This is a very broad spectrum wormer which is effective against internal parasites, including bots and cyathastomes. The Praziquantel is the ingredient used to kill tapeworms.
Used in the late autumn after the killing frost.
 
Fenbendazole (Panacur and Safeguard):
Controls adult and immature roundworms which are the most common equine internal parasites. Used in higher doses, it can control cyathastomes.
Used as part of a rotational summer worming program.
 
Pyrantel Pamoate (Strongid):
Effective against adult internal parasites in horses and foals older than 8 weeks. It can be used as part of a rotational parasite control program and typically is used for deworming foals.
Used as part of a rotational worming program and to deworm foals.

Suggestions to Control Re-infestations

Manure Control:
Manure control is a very effective way to slow down the rate of re-infestations.
 
Remove and dispose of manure from paddocks and corrals at least twice a week.

Harrow or mow pastures regularly to expose larvae and eggs to the elements .

Grooming:
Remove bot eggs that are attached to horses before they can be ingested.

Feeding:
Feed using feeders that are located off the ground.
If possible rotate pastures to prevent overgrazing and reduce fecal contamination.
