Active ingredient of the drug Tanrek: Imidacloprid
Method of penetration of the insecticide Tanrek into the pest body: intestinal, contact, systemic.
Tanrek effectively fights the following pests:
- aphids;

- whitefly;
- leafhoppers;
- Colorado potato beetle;
- apple blossom beetle;
- codling moth;
- cruciferous flea beetles;
- cabbage flies;

Important!
The insecticide Tanrek destroys sucking and gnawing pests, including beetles (ground beetles, weevils), but has no effect on ticks.
Operating principle
The active substance included in the drug Tanrek binds the nerve receptors of the central nervous system of insects, as a result of which paralysis begins in pests, and then death. Due to paralysis, these “harmful” bugs cannot eat, therefore, from the moment the poison penetrates their body, they become harmless to garden and vegetable crops.
There are two lines of this drug:
- Tanrek, VRK against aphids, whiteflies - effectively affects these pests on various garden and vegetable crops;
- Tanrek, VRK from the Colorado potato beetle.

Ways to control cockroaches
Exterminating cockroaches is not just an event that may seem simple at first glance.
The bottom line is that these pests are highly adaptable and also have excellent adaptive mechanisms that have evolved over the course of their evolution. Important! If you are exterminating yourself, then do not use the same cockroach repellent for too long, because they can get used to it and the drug becomes completely ineffective. .

Boric acid is the best folk remedy for cockroaches

In cases where the use of chemicals is impossible (allergies, small children and animals in the house), many are saved by folk remedies. The most famous and best folk remedy for cockroaches is boric acid, which, when ingested by insects, guarantees them a painful death. To prepare the bait, you need to take a raw or boiled egg yolk, pour one packet of boric acid into it, roll into balls and place them in insect habitats. You can also prepare sweet baits with borax powder. Dry boric acid powder can be sprinkled where cockroaches travel (for example, under the sink where they go to drink water). Cockroaches catch the powder on their paws and then lick it off when they clean themselves. But this method is less effective; baits work better.
Advantages
- Safe for people and animals.
- Inexpensive.
Flaws
- The method is effective if there are few cockroaches and the apartment is kept clean. Otherwise, some insects may go to feed, for example, in a trash can, and will not try the bait.
- The balls need to be renewed regularly until the insects disappear completely.
From reviews of boric acid:
“We recommended boric acid for cockroaches. Of course, I didn’t believe that she could really help me, but I still decided to try. I bought a packet of acid, boiled an egg and mixed 1/3 of the yolk with the acid. I made balls, placed them around the kitchen in the evening and couldn’t sleep for a long time, because... I was worried that the balls, on the contrary, would attract even more cockroaches. I had no reason to be afraid! There have been no roommates in the house for a week now! In my opinion, boric acid is the best remedy for cockroaches!
“Whatever recipe you use: with potatoes, raw or boiled eggs, you need to understand that cockroaches run towards the food and eat it along with the acid, because boric acid has neither taste nor smell, they cannot identify it immediately and it corrodes them from the inside and they leave this apartment forever, periodically they send messengers there, so it is better for the messengers not to remove the balls from under the cabinets.
Rating: 8 out of 10.
Preparation of a working solution of the drug Tanrek
How to prepare a working solution of Tanrek:
pour a couple of liters of water into a container, measure out the required amount of product with a syringe, add it to the water, mix thoroughly, then add the remaining amount of liquid.
Advice!
For spraying indoor plants, it is more convenient to prepare such a solution (and spray it) in a plastic bottle.
Prepare the solution immediately before treatment; it can be stored for no more than 2 hours. Remaining liquid should be disposed of immediately after completion of work.
Terms of use
Instructions for use of Tanrek provide for strict adherence to all points. Otherwise, harm is caused to humans, animals, and the environment.
- Spraying should be done in dry, windless weather in the morning or evening. Contact of the active component on a plant on a sunny day leads to burning of the leaves.
- While working, you should use rubber gloves and a protective suit. If spraying against aphids and whiteflies is carried out on tall trees, it is necessary to protect the respiratory tract with a respirator.
- It is advisable to use the finished solution immediately; it is allowed within 2 days. Over time, the product begins to lose its properties. The remains of the unused mixture are allowed to be poured into the soil near the cultivated crops.
- Repeated treatment should be carried out after 20 days. However, the time of harvest must be taken into account. At least 20 days must pass from the last spraying to the consumption of crops.
- It is recommended to use Tanrek VRK in early spring with the first leaves blooming, after harvesting. In special cases - after flowering.
For better adhesion of the active components to the leaves of the plant, a soap base is added to the solution. Safe laundry soap is best suited for these purposes.

Efficiency
Reviews about Tanrek are positive. Experienced gardeners, novice gardeners and flower lovers share their impressions.
I planted petunia seedlings on the balcony. At one point she began to lose strength, and upon examination she discovered small black bugs. Aphids are like a plague to petunias. It will be devoured in a matter of days. Sprayed with Tanrek. The result is obvious the very next day. Within a week my seedlings came to life.
We have a large garden with cherries, plums, apricots and currants. We always use Tanrek for aphids and whiteflies. Initially it was used after flowering, when parasites were discovered one day. It didn't take long to see the effect. After this, we do everything according to the rules - the first treatment of the garden with the drug in early spring, the second - after harvesting.
Saved indoor plants from aphids. Unbeknownst to me, by the end of summer, pests had multiplied in the flower garden on the windowsill. I sprayed with the windows open and did not take flowers outside. One spray was enough to destroy the aphid colony. To consolidate the effect and protect against re-infection, I treated the flowers with the drug after a month. I poured the remaining solution into the pot and worked the soil.

The drug Tanrek: reviews of use
Elena, 45 years old, Moscow region: I have been treating tomatoes and cucumbers in my greenhouse with Tanrek for several seasons, dealing with whiteflies and aphids. In this case, one spraying is enough for these “harmful” insects to die. This drug was recommended to me by a neighbor at my summer cottage, who treats not only vegetable crops with this insecticide, but also fruit trees and berry bushes.
Natalya, 50 years old, Saratov region: I usually use the Tanrek insecticide to treat garden crops as a last resort - when the number of pests is too large. But I can say that despite the number of parasites, this drug kills them all at the same time. The first signs of poisoning in pests appear within 3-4 hours, and they die within about a day.
Nikolay, 38 years old, Volgograd region: My wife and I have a huge garden plot where we grow potatoes for sale. The most difficult period is when the Colorado potato beetle attacks our potatoes. On such a plantation it is impossible to collect it by hand. We tried different products, but Tanrek turned out to be the best - in one treatment this insecticide destroys adult Colorado potato beetles and their larvae. It’s easy to dilute the product and spray it – we usually manage to treat the area in one day, taking a break during hot weather.
The insecticide Tanrek is one of the best drugs in the fight against many pests in the garden and vegetable garden, especially the Colorado potato beetle, aphids and whiteflies.
It effectively copes not only with adults, but also with their larvae, and the plant protection period of Tanrek is at least 2 weeks.

What is the problem?
Tanrek is an insecticide from the neonicotinoid class. These are new synthetic organic compounds unknown in nature; Today, only 5 neonicotinoids are known. At first, neonicotinoids seemed like a godsend: they are highly effective against targets, like pesticides, they have a number of valuable qualities (see below) and seemed low-hazard for vertebrates, incl. fish
However, firstly, all neonicotinoids were immediately assigned the first class of danger to bees. A little later it turned out that these substances are no less dangerous for crustaceans. But a hazard class is a generalized factor with a certain range of hazard parameter values. Tanrek's active ingredient, imidacloprid, is closer to its upper limit. For example, its LD50 for bees is 4-17 ng/individual for oral administration and 24 ng/individual for contact (!). Cypermethrin is from the same chemical class and also has hazard class 1, respectively. values 160 and 120 ng/individual. Those. Imidacloprid is tens of times stronger than its weak “chemical counterparts”, and the ratio of its intestinal and contact activity is the opposite of what they have.
Secondly, the translaminar activity of imidacloprid according to the totality of indicators is also many times higher: in 3-4 hours. it saturates literally the entire plant - from root caps to nectar and pollen. As a result, any non-predatory insect that visits a plant treated with Tanrek, even by chance, is doomed to death. Recent studies have finally confirmed: the main reason for the widespread death of bees and the pestilence of wild pollinators in Europe and a number of American countries is the result of the use of neonicotinoids.
But domestic bees are the main and irreplaceable pollinators. The role of “savages” in plant pollination is several times less - plant biocenoses have long managed to adapt mainly to bees, because As pollinators, they are consistently highly effective, and wild bees have not been able to withstand competition with domestic bees for thousands of years. Plants provide food for all living things, and the complete death of bees is an environmental disaster of historical proportions. Not human history, geological. Therefore, at present, neonicotinoids in the EU are allowed to be used only on protected ground, and imidacloprid is unconditionally prohibited. Are we too late? Time will tell...
And that is not all. All nicotine derivatives, as poisons, have a cumulative effect: their effect increases sharply when they accumulate in the body to a certain threshold concentration. The long-term consequences of systematic use of neonicotinoids are generally the same as those from tobacco nicotine. But imidacloprid also stands out among neonicotinoids for its persistence: its half-life in soil is 100 days and depends little on temperature. In fruits it breaks down faster, but still quite slowly, see below.
Imidacloprid is contained in many pesticides; of the most popular are Confidor, Iskra Zolotaya, Biotlin, etc. But they contain complementary active ingredients that reduce the danger of drugs and simplify their handling. Tanrek – pure imidacloprid, a very high concentration for this class of substances, 20% (200 g/l)
And its preparative form - water-soluble concentrate (WRC) - makes the Tanrek insecticide particularly demanding in terms of technology of use and compliance with precautions when working with the drug.
Therefore, the main rules for using Tanrek:
It is permissible to treat plants with this pesticide only once in the current season; Tanrek should be used only in case of pest invasion on a scale that threatens the entire crop or the existence of a perennial plant; Do not use Tanrek in conditions and/or at times when plants can be visited by pollinators, as well as on plants that they can at least “test”; Although Tanrek is classified as a hazard class 3 for humans, the precautions necessary for working with the drug in private household plots (see below) must be observed with the strictest class higher.
