Cockroaches have been living side by side with humans for centuries. Until the 18th century, Europe was familiar only with black individuals called Prussians.
Thanks to transit from America, we also got red cockroaches, which significantly displaced their black counterparts.
Red cockroach
These insects don’t look too nice, but that’s far from the worst thing.
They are capable of carrying serious diseases:
- gastroenteritis;
- diarrhea;
- dysentery.
When molting, their chitinous cover is destroyed, its remains cause allergic reactions. It is not easy to remove these insects. You can't do without pesticides here. Many people successfully use Fipronil against cockroaches: a description of the active substance and reviews of drugs based on it will help you choose the right way to fight them.

Chemical composition of Fipronil
The empirical formula of this substance is C12H4CL2F6N4OS, but it does not reflect its complex spatial structure.
Chemical formula of fipronil
The presence of toxic halogens such as chlorine and fluorine in the composition determines the insecticidal and acaricidal properties of Fipronil.
Its name is quite complex and sounds as follows: [5-amino-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-[(1R,S)-(trifluoromethyl)sulfanyl]-1H-pyrazol-3- carbonitrile]. This insecticide belongs to the class of phenylpyrazoles.
Preparations based on Fipronil have a very wide spectrum of action and are used for medical and household disinfection, in veterinary medicine and for pest control.
The effectiveness of cockroach repellents based on Fipronil
The main problem with most insecticides is that insects quickly become accustomed to them. When used against cockroaches, fipronil is the active ingredient in many pesticides, resistance, i.e. does not cause stability.
Therefore, the drug can be used repeatedly. Most other pests quickly become accustomed to fipronil-based insecticides.
These substances have both systemic and contact activity against cockroaches. Their peculiarity is that they do not alarm them with smell and taste.
This makes it possible to use Fipronil against cockroaches in traps as food bait.
Insecticides of this class have a nerve-paralytic effect, blocking nerve impulses and disrupting the function of the nervous system of insects.
Death of a cockroach
Paralysis usually occurs within 8 hours after application. The protective effect lasts approximately 2 weeks.
Not only the insecticides themselves pose a danger to insects, but also the corpses of cockroaches, as well as their feces. Therefore, the effect of the toxic substance becomes hurricane and takes on a cascading effect. Typically, up to 95% of cockroaches that have ingested poison die within 3 days. This is very high efficiency.
Operating principle
The basis of the drug is fipronil. This substance has the ability to influence the GABA receptors of external parasites. Under the influence of the active component, fleas, lice eaters and other insects quickly die due to paralysis, which occurs as a result of disruption of the nervous system. When used correctly, all insects parasitizing the animal die within 24 hours.
The drug has a contact effect. Its active substance does not penetrate into the bloodstream, but accumulates in the sebaceous glands, hair and upper layer of the epidermis. Thanks to this, the antiparasitic agent does an excellent job of killing ticks and fleas, but does not have a negative effect on the liver, kidneys and other internal organs.
If Fiprist for cats is used according to the instructions for use, it is considered a safe drug. But the composition contains toxin substances, so the solution should not be allowed to enter the body or mucous membranes.
Popular remedies for cockroaches with Fipronil
Despite the fact that Fipronil was invented in France, at the moment the largest German concern BASF is the holder of full patent rights to manufacture and sell products in Russia and many other countries.
In different countries, Fipronil-based insecticides can be found under the following names:
- Regent;
- Goliath;
- Termidor;
- Combat Ant-Rid;
- Baron.
Quite a few products are available in the form of gels: Domovoy Proshka, Kapkan; Combat Super gel, Eslanadez.
Let's talk about some of them in more detail.
Spray Baron
This product is available in the form of bottles with a volume of 100 ml.
Spray Baron against cockroaches
Active ingredient - Fipronil has a concentration of 0.3%. This is quite a bit, but quite enough to effectively kill insects.
After treatment, even a large colony of cockroaches will die within a week.
Places where cockroaches can hide in the kitchen
The can is convenient to use. Spraying is carried out from a distance of 20-25 cm from the surface to be treated.
The areas where cockroaches most often accumulate are sprayed most thoroughly:
- under and behind the kitchen stove;
- along the perimeter at the bottom of the refrigerator;
- under the sink;
- where the trash can is located;
- next to the microwave;
- under the bathtub and sink;
- next to the ventilation holes and inspection hatch;

Sometimes a single treatment is enough, but to get the result for sure, it is better to repeat the procedure after one or two weeks, this will kill the young individuals that hatched during this time.
To kill cockroaches in an apartment of 50 square meters, just one can of Baron is enough.

- Fipronil at a concentration of 0.03%;
- Imidacloprid at a concentration of 0.5%.
In addition to them, the composition includes gelling agents, a preservative and stabilizer, and sugar. The bitter substance Bitrix, specially included in the composition, will not be to the taste of pets, this will protect them from poisoning.
The gel has an intestinal-contact effect, guaranteeing effective destruction of insects.
Eslandez gel
The protection period is very long - up to 2 months. It is gratifying to note that the gel has only a 4th class of hazard for humans and is considered a low-hazard substance.
The product is available in the form of a syringe containing from 20 to 50 ml of gel. Tubes with a convenient tip contain from 30 to 75 g of the substance.
The gel is a colorless and sometimes white substance, which may have a yellowish tint. Due to its sugar content, the gel is very attractive to cockroaches.
Imidacloprid and Fipronil against cockroaches in the form of a gel are used as follows.
- They clean thoroughly, leaving not a crumb of food behind.
- Squeeze out a thin layer of gel 2 cm long in the form of a dotted line in places where insects accumulate.
- If there are few of them, the distance between the gel strips can be 4 cm. If there are a large number of cockroaches, this can be reduced.
- It is allowed to apply the product to the substrate.
It is especially convenient for use in places that are not accessible to other processing methods.
You can reapply the gel after 2 weeks. This is usually not necessary, since the mortality rate of insects from Eslanadez gel is very high - up to 95%.
Conclusion
The fight against cockroaches is quite difficult, especially if there is a constant source of their possible appearance - living in a neighboring apartment or the presence of a catering establishment in the house.
In this case, not only immediate actions to destroy insects are important, but also constant prevention of their appearance. Correctly selected and effective Fipronil-based products will help you cope with the problem.
