What is the difference between chemical and natural treatment against mites in horses?

The main difference between chemical and natural anti-mite products is the build-up of resistance. After some time, mites can become resistant to chemical pesticides. This is impossible with natural products. But this is not the only difference. The effect is also different. Has your horse been struggling with mites for some time? Read the differences in this blog so that you can make the right choice in the approach to mites!

Chemically kills, naturally prevents new eggs

Chemical pesticides kill the adult mites that come into contact with the pesticide. The latter is an important detail. Mites burrow into the skin. As a result, they are not all accessible to external chemical pesticides. In addition, the fur is also sometimes in the way. Chemical control is a fast treatment that does not break the cycle of mites.

This is a different effect than that natural supplement has. Natural supplements do not kill the mites, but ensure that they cannot lay new eggs. In this way, the mite population is getting smaller and the cycle is broken. This way takes longer, but is more effective in the long run.

External vs. Internally

Mites are so difficult to treat because they are virtually inaccessible. They are under the coat and burrow into the skin. External treatment is therefore difficult and not always effective. Treatment from the inside, combined with external treatment, is therefore preferred. This allows you to reach the mites from two sides. With an internal product always choose 100% natural such as Finecto+ Horse.

Neither influence on hatching eggs

Did you know that no pesticides control mite eggs? Neither chemically or natural. This is why mites seem to keep coming back during chemical treatment. The adult mites were killed during the treatment, but the eggs that had yet to hatch were not. That is why it is so difficult to get rid of mites purely because you are dealing with the eggs that have yet to hatch. Therefore, do not stop treating as soon as your horse seems mite free, but keep going for a while. You do not want the newly hatched mites to lay new eggs. A natural internal supplement prevents this.

Harmfulness to horse health

An indirect side effect of chemical pesticides is that they can have an adverse effect on the liver and kidneys when used frequently. Many horse enthusiasts do not adhere to the dosage or use agents that are not actually intended for horses and yet continue to treat them as soon as they see that the symptoms return. This has the effect that the health of the horse can be affected in the long term. This is not the case with natural products. That is why natural supplements are recommended, especially if your horse has more mites.


Chemical pesticides are only effective in the short term because they only fight the adult mites that can be reached. The mites that have burrowed into the skin and the mite eggs are not controlled. This makes it seem as if the mites have suddenly returned after a few weeks. This is because chemical pesticides do not prevent newly hatched mites from laying eggs. This is a property that natural herbs have. These ensure that they can no longer convert the blood or skin flakes into new eggs. This immediately interrupts the cycle as soon as new eggs hatch. In addition, mites cannot build up resistance to natural herbs, but this is the case with chemical agents. And perhaps most importantly: natural control has no adverse health effects for the horse.
