Let's try to figure out whether tansy can help in the fight against bed bugs in the apartment

Along with the wormwood tansy from bedbugs is considered one of the most effective herbs. This small and widespread plant that fills with its small bright yellow flowers of wasteland, meadows and roadsides, has long been known for its poisonousness and ability to cause the bitter taste of milk in a cow grazing on its thickets.

Tansy is considered a medicinal plant that is effective against insects.

In agriculture, even in ancient times, decoction and infusion of tansy was used to treat plants in vegetable gardens for pests. Even today, in many farms that work on the principles of environmental friendliness and organic farming, tansy is still used to protect potatoes from the Colorado potato beetle, and trees from caterpillars feeding on leaves.


“In the village, this is just a tradition - a decoction is prepared on tansy, with which potatoes and apples are sprayed. And the remnants of a simple broom are applied on the joints of the floor and walls, baseboards and furniture.I even when I was little, walked like that with a broom around the house and squirted - my grandmother told me that tansy from bugs very well protects. ”

Julia, Ulyanovsk

Against bedbugs Tansy is applied by analogy with its use from insects in gardens and vegetable gardens. But there is an important nuance: if against the same Colorado potato beetle or potato moth, the remedy works like a poison, poisoning an insect that has eaten it, bed bugs in a room, in principle, cannot eat tansy or something that can be processed by it. After all, the only food of bedbugs is human blood.

The tansy is not as effective against bedbugs as it is against some pests of the vegetable garden, since the bugs feed only on blood.

How and at the expense of what then the tansy works against bed bugs? Let's try to understand this issue in more detail.


How does tansy on bedbugs?

First of all, tansy is an effective repellent: its smell frightens off all kinds of insects, even mosquitoes. The bugs are also afraid of this smell.

However, if these parasites were bred in an apartment and relatively long ago established their nests here, it is almost impossible to destroy them with the help of tansy. In order for the bug to die, it must literally be dipped into a decoction of tansy so that the agent in a liquid concentrated form gets into the body of the insect through the respiratory tract (spiracle).

Tansy can only be used to scare away bedbugs, but not to destroy them.

If a surface is simply treated with a decoction, then the bug can run around such places in the house without any harm to itself.


“We also tried tansy. Does not help. Bugs run away from her, but do not die. Crush them with a sneaker lazily, and pour this broth so that they die - it’s necessary to flood the neighbors from below. And the branches under the bed lay down, also did not help. Probably because part of them lived in the bed itself. ”

Ilya, Saratov

Effective use of tansy from bedbugs in order to temporarily weaken their activity. Having felt the smell of this substance in the room, insects for some time (usually up to 3-4 days) will avoid appearing in places where this smell is the strongest. However, later they still get to the person.

If there are many bugs in the room, then tansy will not be able to scare them away from the person for a long time.

This does not mean that tansy from bedbugs does not work at all, just the hunger for parasites is always stronger than the “fear” of the smell of grass.


Tansy: instructions for use against parasites

The use of tansy against bedbugs is quite identical to using wormwood for the same purpose. In the simplest version, freshly picked or already dry sprigs of the plants are laid out under the bed mattress, in sofas and armchairs, in the corners of the room and under linen closets and bedside tables.

To scare away bedbugs, you should chop tansy and place fresh or dried parts of the plant under a bed or sofa.

If such a valve from the plant is located between the refuge of bedbugs and the resting place of people, then until the parasites get very hungry, they will not cross it. However, later they will still decide to break through such a “cordon”.

Although bugs are afraid of the smell of tansy, it will not stop them for long.

A little more difficult is the use of tansy as a decoction. In this case, a glass of dry grass is boiled for a minute in five liters of water, then cooled.

Prepared from dried flowers of tansy broth, you can handle the corners of the apartment and the floor under the bed.

Broth sprinkle plinth in the house, parquet, linoleum corners and cracks. Usually after such processing, the bugs try to leave the cracks, and already in the open space they can be simply crushed or destroyed by other means.

Of course, tansy has no effect on bedbug eggs at all.

“Bedbugs appeared last year in the spring. I do not know where, but there were few of them, and only in the child’s room. We did this: carried the crib to the loggia. Fortunately, the weather allowed. The room removed the carpet and carried it to the sink. After that, the whole room was literally poured with a decoction of tansy with wormwood. We bought a kilogram of wormwood and half a kilo of tansy at the market, cooked it in an enamelled bucket, poured all the plinths, drawers in the closet, a radiator. The bed itself was also processed, the mattress was thrown out of it, all diapers were washed in a washer at the maximum temperature.You should have seen the bugs run away from under the baseboards. Exodus bedbugs just some. We crushed them all right there, both big and small. And so - three weekends in a row. And that's it, they brought everyone out. But we were lucky that they were only in one room. ”

Pavel, Nazarovo

Much more effective is the use of tansy in conjunction with industrial insecticides. As the second component, you can use any aerosol or concentrate from insects.

It is best to combine tansy with any modern insecticide, for example, with an insect repellent Get.

On a note

One more folk remedy for bedbugs is a tincture of tansy on alcohol. The tool turns out to be both frightening and deadly for bedbugs: alcohol burns the parasites and causes them to die if they hit the insect directly. This infusion previously recommended to handle the nests and accumulations of bedbugs.


Tansy for the prevention of bedbugs in the house

Tansy is more effective as a preventive measure against bedbugs: with its help, it is quite possible to protect the premises from the penetration of isolated parasites, for example, from neighbors.

The most effective tansy with a small number of bugs in the room.

For this, it is usually recommended:

  • lay the plant under the mattresses of the bed and in the internal cavities of the sofas
  • add a decoction of tansy in the water, which wash the floors
  • decorate the ventilation ducts in the apartments, external slopes of windows and walls around the entrance doors.

Prepared bunches of tansy should be laid out in places where it is desirable to scare away bedbugs

With this treatment, cases of penetration of bedbugs from neighboring rooms and just from the street are almost excluded.


Can tansy be dangerous?

Generally speaking, tansy is a poisonous plant, and when working with it you need to exercise some caution. For example, it is necessary to keep the preparations out of it away from children, not to allow the plant to enter the cells with domestic rodents.

Treat with decoction or infusion of tansy bed bugs places on the body can only be in accordance with the instructions for the use of these funds.

When bedbugs bite, you should not self-medicate and use tansy uncontrollably, which is a rather poisonous medicinal plant.


“The first thing that came to my mind when the bugs appeared was tansy, but somehow it was scary to process the whole apartment with it. This is a poisonous plant, even the cattle it is poisoned. But then she decided, brewed broth, squirted everything. For a while they did not bother after that, and then reappeared. Probably, it needs to constantly process the apartment, but I do not have time for this. Therefore, we planned three weekends and called the SES. They processed everything, we cleaned the house and left for the country. After that the bugs were gone. ”

Hope, Fominskoe

In general, you can not be afraid to use tansy: take it with your hands, sniff and use its broth in the room is quite safe.

Once again, we note that if the bugs in the room are wound up, it will not work to bring them out of the tansy alone - it simply will not act on them like an insecticide. Therefore, initially it is necessary to focus on special modern insect repellent pests.

    Just some kind of crap, well, kindergarten right. Are there people who believe that tansy can destroy bed bugs? And how long will it last? Week, month, year? Who will have so much patience to try all this time to poison these parasites with a decoction of tansy? Maybe it is better to take a normal remedy, Geth, for example, and do away with bedbugs in one fell swoop?

    • Alexey:

      The only means by which you can destroy bedbugs in one go is a fire.

  2. Roman, Yekaterinburg:

    We stopped to live in an old house, called pickers on the ad. They said that we would forget about all the living creatures for half a year ... And for sure, day after day, we climbed out again. I bought Combat superspray plus, and after that I will cover all with tansy, as prevention. By the way, the bedbugs nest can not find.

  3. Tatyana:

    I live in Podolsk, I called Klimovsky DEZ 5 times, there are bugs. And they bite me alone, but they don't bite my husband and children. I do not know what to do, help!

    • Helena:

  4. Artie:

    50 g bag of tansy once a day. Bought at the pharmacy. I prepare the tincture as follows: 400 grams of water, a bag in a small saucepan. I boil for 1 hour, then add another 1 liter of hot water. Waiting for 1-2 hours. Then I spray all over the apartment, where wooden objects. The second day we feel the result. And I hope that the bugs will go back to where they came from (to a neighbor). So I will continue until the summer. I will bring fresh tansy, 100 kilograms. I’ll shower it all over the house, that's all.

  5. Sasha:

    In the apartment building with wooden floors, the bugs move from apartment to apartment, under the floors freely. If in some apartment they are poisoned by sharp odors, then they leave to the unsuspecting neighbor. They fought with cockroaches like this: they glued Kotofey mice for glue on the thick cardboard around the perimeter, laid them under the refrigerator and other places on the floor. And in the middle they put pieces of food.
