Application of phenaxin from bedbugs: reviews and instructions

Порошок Фенаксин можно применять не только для уничтожения клопов, но также от блох и тараканов

The phenaxin powder produced by Agrovit is a universal remedy for bedbugs, cockroaches, fleas and other insects. Its composition includes pyrethroid fenvalerate, which has a contact-intestinal effect on insects, and also known in the fight against insects - boric acid .

Often, universal remedies do not always have a sufficient effect on individual parasites, in particular bugs, which in general are quite difficult to destroy. So let's see how effective, according to buyers, Phoenaxin is showing himself exactly in the matter of getting rid of bed bugs.


Phenaxin, of course, is well applied to flat surfaces such as the floor under the carpet, but, as it turned out, bedbugs are found not only there. Still inconvenient, that the slightest draft will blow this powder around the house. I scattered the remedy under the mattress and under the carpet, there the bedbugs were killed, but after a while they appeared again from somewhere.

Phenaxin and Phenaxin Plus: what means to choose for fighting bugs?

In addition to the phenaxin powder, one can find on the sale one more remedy with the almost same name - Phenaxin Plus. Since it is produced by the same firm Agrovit, you might think that this drug should have an even stronger effect on bugs, cockroaches, fleas and other insect parasites.

Средство Фенаксин Плюс от медведки очень похоже внешне на Фенаксин

In fact, the distinctive feature of the drug phenaxin plus is its release in the form of granules, which are used in agriculture to combat the bear. Although in its composition - a powerful insecticide of the organophosphorus group called malathion, the effect on domestic parasites, for example, on the same bedbugs, it will not practically do. After all, bedbugs are bloodsucking insects and will not eat this remedy.

Клопы просто-напросто не будут поедать средство в гранулах

In addition, if the powder is able to adhere to the limbs and covers of insects, then the agent in solid granules will not be able to gain a foothold on the chitinous cover of the parasite. Buying phenaxin, this moment must be taken into account.


Fenaksin immediately attracted me by his cheapness. Bugs we did not have much (I do not even know where they came from!), And I decided to start with inexpensive means. I did not like it very much, that it was necessary to disperse the powder through the punctures in the bag: while it was scattering it, probably, breathed, then the sneeze began. But, in general, until after the treatment bugs did not appear.

Powder safety Fanaxin

As already noted above, phenaxin powder contains an insecticide from the group of pyrethroids - fenvalerate.

В составе порошка Фенаксин - пиретроид фенвалерат

Like all pyrethroids, this insecticide has a weak toxicity to humans, but its activity against eggs of bed bugs is also not sufficiently pronounced. Actually, the structure of pyrethroids resembles the structure of natural insecticides called pyrethrins, which are contained in the flowers of some species of chamomile and from which, by the way, Pyrethrum powder is also prepared, which is also quite effective against bedbugs.

В некоторых видах ромашки содержатся натуральные инсектициды - пиретрины

The mechanism of action of these poisons on bedbugs is based on the disruption of the work of their nervous system, followed by paralysis and insect death. Modern synthetic pyrethroids are quite stable in the light, and therefore have a long-lasting effect on parasites (about a month), refer to the 3rd class of danger for humans and domestic animals. Nevertheless, in accordance with the instruction, during the treatment of the premises it is necessary to transport your pet to another place, or at least try not to lick the treated surfaces with animals.


Pyrethroids have a pronounced toxic effect on fish and bees, so when planning to use the phenaxin drug, it is best to remove the aquarium from the room for a while if you have it.

The advantages and disadvantages of the tool

Speaking about the merits and demerits of the drug phenaxin, it should be noted that it is effective only with a small number of bedbugs in the apartment, and people's testimonials about this are good evidence. Moreover, the already laid and well hidden in the folds of the mattress or in the cracks on the wall of the egg bed bugs it will not have practically no effect.

Клопы могут хорошо прятаться внутри матраса

It should also be understood that the boric acid powder commonly used to control cockroaches in the phenaxin will not have any effect on bed bugs, because these parasites feed exclusively on human blood. The action of boric acid on cockroaches is based on the ingestion of this substance inside the insect and the subsequent dehydration of its body.

На таракана борная кислота еще может подействовать, а вот на клопов - нет

Also, due to the fact that bed bugs, unlike cockroaches, move relatively little about the dwelling and practically do not carry the product on their paws, the insecticide in the form of a powder will not have a massive damaging effect on the whole colony (nest) of parasites, so its it is better to use in combination with any additional insecticide.

Nevertheless, phenaxine, as a remedy for bedbugs, also has a number of advantages when compared with some other drugs. First of all, we note the following positive points:

  • low price (about 40 rubles per package);
  • sufficient safety for humans and pets;
  • not too pronounced smell.

The main disadvantage of the remedy is, perhaps, that the eggs of bed bugs in places inaccessible for powder processing can safely continue to develop, which means that after some time after treatment the bugs will necessarily appear in the house again.

Если яйца не были уничтожены при обработке, то вскоре клопы появятся вновь


In the student years in the dormitory I had to fight mercilessly with bugs , and the phenaxin powder (because it was the cheapest of other means) was poured on them and sprayed with aerosol and the girl's bedding was boiled. Only while the mattress on one of the beds in the block did not change, nothing did not help!

How to use the product according to the instructions

The drug is sold in bags of 100 or 200 grams. One package is usually enough to process an area of ​​about 30 square meters. m. (at the rate of 5 grams per 1 sq. m.). According to the instructions, a bag of phenaxin to get rid of bedbugs should be pierced at certain points and scattered powder through the resulting holes in the places of the supposed congestion and movement of bedbugs: these are the surfaces of furniture, the floor under the carpet, the bed under the mattress,

Фенаксин нужно рассыпать ровным слоем во всех местах скопления клопов

The powder can keep its activity for about a month, so in places inaccessible to children and animals, it can be left there for a long time. However, everyone knows that in a house where there is a child or a curious pet, such places sometimes simply can not exist. Therefore, after a few hours after treatment, it is best to wipe the surface with a damp sponge soaked in a soap-soda solution, and ventilate the room itself.

If the effect of the drug Fenaxin was low, this may indicate that the number of bed bugs in the house is clearly greater than the estimated. In this case, the treatment can be repeated after a while, combining the phenaxin powder with another insecticide in the form of an aerosol.

In addition, it must be understood that in itself no miracle cure for bedbugs will help, if you neglect the complex treatment of a home, including washing in hot water of bedding.

    For about 3 years I have been using phenaxine against cockroaches. I recommend a very good remedy, it works 100%, cockroaches just 5 minutes after the spill go crazy, and through the night they die. A very small number survives, but the sneaker does the trick.) The downside is that it affects little cockroaches.

      Applied phenaxin against black cockroaches, the result is! Began to die, only on the 3rd day the effect was asleep. These Chernobyl cockroaches, already on the third day of free running. The trouble is that in my city phenaxin is all overdue. The drug is good, even with the expired term kills cockroaches. Travle these creatures in the yard, it works very well! I recommend. The most effective drug against cockroaches.

  4. Irina :

    How many people, so many opinions. Bedbugs are almost impossible to withdraw. Only by own strength. And about the call of disinfection is an empty number, a waste of money and time.
