All gastrointestinal worms have their own cycle, but the process is basically the same. The larva is eaten by the horse and migrates through the body. The larva becomes a worm that lays eggs. The eggs arrive on the land with the manure, where a larva hatches from the egg and the cycle starts all over again. Removing manure from the land is therefore very important to prevent (re)contamination.

The larvae of the red bloodworm have the special property of being able to encapsulate themselves. However, the larvae encapsulate themselves, but any worms present still lay eggs. That is why it is important to have manure research carried out throughout the year. For more information, visit www.wormenco.nl/wormen

Horses up to 2 years old have a greater chance of contracting a roundworm infection, after which natural resistance is built up. That is why we rarely see roundworm infections in older horses. For more information go to www.wormenco.nl/wormen

Below you will find the cycle of the liver fluke. We have been seeing liver fluke infections more and more often in recent years. The unique thing about the liver fluke is that the larva needs an intermediate host (the liver fluke snail) to reproduce. For more information, please visit www.wormenco.nl/wormen.

Below you will find a schedule of all active substances available for gastrointestinal worms in horses. We see a growth in resistant worms, which is why it is very important to have a manure test done before deworming.
