Fipronil: sanitary and agricultural insecticide

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.

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:

1. Gel against cockroaches "Hector";
2. Regent;
3. Goliath;
4. Termidor;
5. Combat Ant-Rid;
6. 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.

Gel bait against cockroaches "Hector"

Gel bait (syringe) "Gektor" has a fipronil concentration of 0.05% in its composition! This gel can quickly exterminate pests such as cockroaches. Self-treatment of a room with gel is a big blow for all cockroaches and does not create inconvenience in the form of an unpleasant odor or wet surfaces as after the work of exterminators. The long-term effect of the gel makes it impossible for newborn insects to survive.

The gel is considered effective until it dries completely! In rooms with high humidity, the gel retains its properties much longer!

Hector gel can attract cockroaches within a radius of up to 1 meter. No matter what the insect ate before, it will definitely eat this toxic gel.

After the cockroach is poisoned, it will be able to penetrate the nest of its fellow tribesmen and infect them there. When contacting infected cockroaches, their healthy “relatives” can also become infected.

You can simply lightly touch the cockroach with Hector gel to infect it. Infected insects cannot expand their species. As a result, the entire group of cockroaches will die out.

Gel against cockroaches "Hector"

The Hector gel treatment method for cockroaches is as follows:

• First, remove the cap from the syringe tip;
• Then press the tip of the syringe onto the surface to be treated;
• Gently squeeze a small amount of gel, no more than 1 ml, onto the surface. (the size of a small “drop”);
• The consumption should be 4 drops per square meter;
• After use, wash your hands thoroughly with soap and water.

When processing, pay attention to the following areas:

• Along and inside the baseboards;
• Behind the door panels;
• The back surface of cabinets, refrigerators, stoves;
• Gaps between shelves and walls;
• In ventilation;
• Behind the sink;
• Under the bath;
• Areas behind and under furniture;
• Near the trash container;
• Behind the peeled wallpaper.

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;
• baseboards in the hallway;
• in the area of ​​the entrance door along its entire perimeter, including platbands.

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.

1. Fipronil at a concentration of 0.03%;
2. 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.

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%.

Fipronil contamination of eggs, 2022[edit]

Main article: Fipronil contamination of eggs 2022

The 2022 fipronil egg contamination is an incident in Europe and South Korea involving the spread of eggs and egg products contaminated with insecticides. Chicken eggs have been found to contain fipronil and are distributed in 15 European Union countries, Switzerland and Hong Kong. [34] [35] It is believed that around 700,000 eggs were put on the shelves in the UK alone. [36] Eggs from 44 farms in Taiwan were also found to have excessive levels of fipronil. [37]

fipronil: ecotoxicity

Side effects

Fipronil has low (grade 2) dermal toxicity and moderate (grade 3) oral and inhalation toxicity. When applying the drug to the dermis, short-term skin reactions may occur: redness, itching, rashes, loss of fur at the site of application.

If the drug enters the intestines, symptoms of neurotoxic damage may occur:

• tremor of the limbs;
• vomit;
• increased salivation;
• convulsions;
• abnormal gait;
• depression;
• increased nervousness;
• hunched over.

The same signs may appear when Fipronil is inhaled if the spray is handled carelessly. In case of severe poisoning, lethargy, convulsions and death of the animal may occur. It has been found that dogs are more sensitive to the substance than cats.

An overdose can also provoke an allergic reaction, breathing problems, and heart palpitations. Symptoms of poisoning can be eliminated by administering barbiturates.

Action

Fipronil is a neurotoxin (nerve poison) of intestinal and contact action. In animals, it binds to γ-aminobutyric acid (GABA), the most important mediator (regulator) of the passage of nerve impulses through the chlorion channels of nerve cell membranes. Without the mediator “turned off” by fipronil, the nervous system becomes overexcited to the point of convulsions, followed by a reaction - paralysis and death.

The specific mechanisms of transmission of nerve impulses to muscles in different groups of animals are significantly different. Fipronil is quite highly selective against insects, incl. resistant to carbamates, pyrethroids and FOS. However, the objects of elimination develop tolerance to this substance, therefore, in agricultural technology, pesticides with fipronil are used in rotation to avoid resistance of pests or occasionally during their mass invasion. In the fight against resistance, fipronil is used as a replacement drug, because actively accumulates in plants, and moves along the soil profile slowly and to a depth of no more than 30 cm.

The speed of action of fipronil as an agrotechnical insecticide is low - the death of insects begins 8-10 hours after treatment. The effectiveness is also not 100% - after a day, up to 15% of pests survive. However, the protective effect is long-lasting, 14 days or more, and the drug is not washed off by rain. Therefore, on land areas, fipronil is most effective against massively migrating pests: when the density of individuals and the total volume of the wandering mass decreases below a certain limit, it stops migrating, and the surviving individuals scatter across the area and, “not feeling the shoulder of their fellows,” quickly die, leaving no offspring, like ants isolated from an anthill.

Note : Since 2003, fipronil has been recommended by the FAO (Food and Agriculture Organization of the United Nations) as the primary control agent for desert locust infestations.

Insecticide "Brownie Proshka"

Gel "Proshka Domovoy" showed high efficiency

This product may seem unsightly, and it is not at all advertised. But it is worth noting that the drug is domestically produced, comes in a convenient gel form, and contains a high percentage of such an effective substance as fipronil against cockroaches. By purchasing this gel, you already receive a ready-made bait, which you only need to apply at home to the expected places of movement of pests.

“Domovoy Proshka” has many advantages: it contains the effective component fipronil, the product is convenient to distribute and apply, has a low cost, but is of good quality. But when working with any insecticides, do not forget about the rules of personal safety.

Fipronil is a toxic substance that is included in many effective drugs for killing various household pests. Due to its high toxicity, the drug cannot be used to treat rooms where children or pets live. Often, if you work carelessly with fipronil, a person experiences headaches, nausea, dizziness and skin irritation.

Reviews from owners and veterinarians

Ekaterina, 45 years old, Murmansk: “A cat and a dog live in my apartment. Bobik and I often walk in the forest belt and go into nature, so we need a strong anti-tick remedy. Marusya stays at home, but she can become infected with insects from the dog.

Instead of drops, I decided to try Fipronil spray. It is not only effective, but also economical. For 2 adult animals, a 250 ml bottle is enough for 4 treatments.”

Vladimir, 32 years old, Moscow region: “I live in my own house. That's why my 2 cats roam freely around the yard. Last year it was a hot summer and the fleas were overwhelming. I had to look for a good, reliable product with a prolonged effect.

At first I bought Fipronil drops, but the seller recommended a spray. There is much more of it and you can treat your pets during the entire period of flea and tick activity. I bought a 100 ml container. There’s even left for next year.”

Olga, 23 years old, Nikolaev: “3 kittens were dropped off at my place of work. We took them home. The babies were heavily infested with fleas. I washed them with special shampoos, tar soap, and combed them. But after a while they appeared again.

On the advice of the veterinarian, I dropped a few drops of Fipronil onto the withers. The kitten was approximately 2-3 months old. I watched the reaction for 24 hours, but everything turned out okay. But I didn’t see any more fleas.”

Kaleria, veterinarian, Tambov: “I use insecticides with fipronil myself to treat pets and recommend them to my clients. If you follow the rules of use, the product is safe, effective and relatively inexpensive.”

Sergey, veterinarian, Vladimir: “For fleas and ticks, I recommend Fipronil spray. It is capable of killing adult parasites and their larvae. The spray is convenient to use for treating cat beds, but after that they need to be thoroughly ventilated and fried in the sun. I recommend testing for an allergic reaction before use so that you don’t have to treat your pet later.”

Instructions for use

Fipronil is included in a variety of drugs, each of which has its own purpose, so there are no universal instructions for it - in each specific case you must follow the instructions provided by the manufacturer. The only condition common to all drugs is compliance with standard safety measures:

1. While working with the substance, drinking, smoking and eating are prohibited. The face should be protected with a special mask, hands with gloves, and body with tight-fitting clothing to prevent the drug from coming into contact with exposed skin.

   
   Take precautions when treating with Fipronil to avoid poisoning

2. The dishes that were used to prepare the working solution should not subsequently be mixed with kitchen utensils.
3. Fipronil should not be used near ponds or aquariums. During treatment, there should be no small children or pregnant women nearby. If the drug is used as part of a food bait, the latter is positioned so that the child cannot reach it.
4. At the slightest symptoms of poisoning (dizziness, nausea, vomiting, general weakness, etc.), you should immediately consult a doctor.

Anti-flea products with Fipronil are contraindicated for puppies and kittens under two months of age, as well as adult animals with weakened immune systems.

The substance has the first and third classes of danger for pollinating insects (depending on the purpose of the drug, which includes Fipronil). Hazard classes for humans - second and third.
