About This Item
BioWorma is a biological pasture dewormer for livestock, horses, cattle, goats, and other grazing animals. Unlike chemical dewormers, BioWorma targets worm larvae in animal manure before they can reinfect pastures, breaking the worm cycle at the source.
Its active ingredient, the naturally occurring fungus Duddingtonia flagrans, traps and consumes worm larvae in manure, including chemical-resistant strains. This makes it especially effective for herds where chemical dewormers alone are no longer working.
BioWorma works best as part of an integrated parasite management program. Use it alongside a standard dewormer to eliminate existing worms, then continue daily BioWorma feeding to prevent reinfection from pastures. Over time, this reduces the overall worm burden on your property, not just the animals.
Highly effective for young animals and breeding females. Regular use reduces pasture contamination, lowers reinfection rates, and minimizes the need for repeated chemical treatments.
Available in 15lb size. Exotic Animal Supply is one of only two authorized US sellers of BioWorma.
Instructions
Before starting BioWorma, treat animals with a suitable injectable, pour-on, or oral dewormer to eliminate existing worms. Once treated, move animals to low-worm pasture that has not been grazed by the same species for at least 6 weeks.
Thoroughly mix BioWorma into feed, supplements, premixes, or concentrates at 0.1 oz per 100 lbs of animal weight. Use the heaviest animal in the group to determine the correct amount, up to 1,200 lbs.
For animals over 1,200 lbs, add an additional 0.1 oz of BioWorma for each additional 100 lbs of bodyweight.
Administer the mixture daily under conditions conducive to parasitic activity. Continue daily feeding to minimize pasture infectivity and maintain low worm levels in your herd.
For best results, use BioWorma as part of an ongoing parasite management program rather than as a one-time treatment.
FAQs
Is BioWorma a replacement for regular dewormer?
No. BioWorma doesn't treat worms already inside the animal. Use a standard injectable, pour-on, or oral dewormer first to clear existing worms, then start BioWorma to prevent reinfection from the pasture.
Is BioWorma safe for pregnant or young animals?
Yes, it's noted as especially effective for young animals and breeding females, since these groups are most vulnerable to pasture reinfection.
Why buy BioWorma from Exotic Animal Supply?
Exotic Animal Supply is one of only two authorized US sellers of BioWorma.
Does BioWorma need to be mixed with anything?
Yes. Mix thoroughly into feed, supplements, premixes, or concentrates at the rate listed above, based on the heaviest animal in the group, up to 1,200 lbs.
Bioworma has been having problems with shipping from it's manufacturer in AU. Thankfully this company got a restock (and I find that they are usually more stocked than the only other supplier in the U.S.). Will continue to get my supply here for my animals!
Terrible customer service. Shipping way outside their posted policy. Nowhere on thw site did it say the item was out of stock/not in a stateside warehouse. Claim on the site to have four US warehouses, yet this product had to ship in from Australia first. When the item did finally arrive, the product container inside the box was smashed- NOT the shipping box, that loked perfectly fine on the outside. Inside the shipping box, the actual product container was smashed horribly. Only giving two stars because I needed the product for my livestock and did finally get something. Would not order through this particular company again, though.
