How does fly spray kill flies

Insecticides (kill insects)

Synthetic insecticide. The main active ingredient is very similar to the natural insecticide pyrethrum (obtained from the leaves of the chrysanthemum). Available in stores since around 1977.
Deadly to insects. The insects absorb the active ingredient permethrin through the surface of the body, and it is then distributed throughout the insect's body. Permethrin is contained in many products for dogs, for combating lice, fleas, mites, ticks, etc. Ear tags also mostly contain permethrin, as is the Well-Care product available from the vet. Permethrin must never be used in cats, as they cannot break down the active ingredient and die from it.
Effect: insecticide, deadly to insects
Products containing permethrin: Absorbine Ultra Shield Ex

The insecticide was developed by the U-Marien as early as 1917 and was further developed in the course of the following decades. Sprays containing this ingredient kill insects. Pyrethrins are also used as repellants. Products with pyrethrins are mainly used in products for the home garden or in the greenhouse.
Effect: insecticide, deadly to insects
Products containing pyrethrins: Absorbine Flys-X

Repellent (repels insects)

DEET (N, N-diethyl-m-toluamide, diethyltoluamide)
Chemical insect repellent. Developed around 1946 and is the most commonly used repellent. Insects are repelled, although it is not conclusively explained whether the insects are blocked by the scent recipe, or perceive the scent and taste and avoid the animals that are treated with it.
DEET are found in many commercial insect repellants for humans, such as: B. some varieties of Autan (tropics). The WHO certifies that the product has an excellent effect.
Effect: repellent. Defensive, the animals are no longer approached by insects

Some readers will wonder why one fly spray with apparently the same main active ingredient works better than the other. On the one hand, it is due to the overall formulation of a spray that influences the effect of a repellent or an insecticide. These recipes are carefully guarded by the manufacturers. On the other hand, the manufacturers put the active ingredients in the recipe in different concentrations. Products such as B. the Effol Brake Blocker + have a higher concentration of the main active ingredient DEET than the product from the company Busse. Some sprays such as B. the Ballistol Stirchfrei also have UV protection, other sprays also care for the coat similar to a coat care spray. All of these features may explain the different prices.

So what's better, kill insects or keep them away? We all don't want to breed stinging insects or flies, so it makes perfect sense to treat the barn and the corresponding rooms with a killing spray (Absorbine Ultra Shield ex barn spray) in order to destroy larvae, eggs and insects themselves if they get out of hand . A TAON insect trap also does a good job, as do insect traps that can be hung in rooms. Because the fact is, when the effect of a repellent wears off, the insects come back immediately. Sufficient hygiene in the stable should be ensured permanently so that no unwanted insects can multiply. Effective micro-organisms such as the Emiko stable cleaner do a very good job here.

Logic explains that horses, and we humans too, were more comfortable when stinging insects were kept away, i. H. if we and / or our horses are not even approached. Many horses already react nervously to the noises of stinging insects. Treated horse blankets or fly masks are also supposed to keep biting insects away.

When using insect sprays, it is important to fog your horse over the entire area. The repellent repellants make no sense if you only spray the stomach and neck. Please do not water your horse with fly spray either, but mist it all over. This saves spray in the long term and simply works better.

Basically: All main active ingredients, even if they are of natural origin, have been classified as biocides. Therefore, please read the description on the packaging beforehand and, so that there is no surprise with your horse's allergic reaction, simply try it on a small area and wait 6-8 hours.
