What to do if mice have gnawed grapes?

The snow came down, it got warmer – I went to the vineyard after wintering and found that many bushes were thoroughly gnawed. Why would this happen and what to do with the affected bushes now?

Some grape growers, as soon as the snow had melted, decided to check the grapes. And, unfortunately, they found vines damaged by mice under the tunnel dwelling. They especially complain about the fact that the bark and the eyes of annual vines are severely stroked. It is noted that mice damage to vineyards is observed in areas of remote dachas with forest belts or forests and agricultural land nearby. Why did this happen and how to save the vineyard now?

The past winter brought many surprises. It snowed several times in many regions. At the same time, the snow cover sometimes reached more than a dozen centimeters. If snow was wet or if it rained, an ice crust would form on the ground, covered with a thick layer of snow. In such conditions rodents lost free access to their usual food: seeds of plants, their shoots, etc. Mice move quickly and easily under a layer of loose snow. But the ice crust on the surface of the ground is a serious obstacle for you. Therefore, in search of available food. Exactly such food can be vines under tunnel housing (under crates, slate, film, etc.), which you can chew through cleaner than all rabbits. Vineyards under vineyards near forests or wooded areas, fields that have been occupied by cereals or sunflowers are especially hard hit. There are fewer mice in residential areas and usually the threat of vineyard damage is much lower.

So what should be done if such a mishap has occurred and rodents have damaged a vineyard? First of all, the extent of the damage must be assessed after being free of Winterheim. If only individual barriers are damaged (some years sleeves and stamps are rarely gnawed by mice), then the shoots on which rodents completely nibbled the bark and took out the buds, let the eye on the base of these shoots. On them, young shoots will develop, from which fruit boles or replacement nodes can be formed the next year. If only individual pruning areas are damaged, you should cut off the most damaged ones and those with no intact eyelets left. From the remaining, even short vines, it will be possible to save a small harvest and form new fruit connections at the expense of the grown shoots. The main thing, if the vineyard turned out to be very strong, even very strong, there is no need to rush to take up the shovel and fold the grape bushes. Over the season there is every chance to restore them and get a full harvest next year.

Grapes are being damaged by mice

In the fall, gardeners spray wine bushes for pests and protect them from frost. Plants also need to be protected from rodents. If mice have gnawed grapes and found it in the spring, there are ways to combat this plague.

What to do if mice have gnawed the bark of grapes?


In early spring, just after the snow melts, it is necessary to check how the vineyard has overwintered. It is not uncommon to find that mice have gnawed the vine under the protection of the tunnel.

The bark and eyeballs of annual plants suffer the most. Mass attack of rodents is usually observed in gardens located near the forest belt or fields.

Why does this happen?

There are winters with large temperature variations. Snow falls, melts, and freezes again. An ice crust forms that prevents rodents from grabbing their usual food: seeds, sprouts.

Mice dig holes in snowdrifts very easily, but the ice crust becomes an insurmountable obstacle for them. Therefore, the rodents look for other food, which they do not pay attention to in normal winters. Vines under cover are easy prey.


Immediately after recognizing plants that have been found, assess the extent of damage. If individual vines are damaged, the most affected shoots are cut off, with the eyelets remaining at the base.

Several years of rodents are usually unaffected. New shoots grow from the rescued eyelets, which need to be shaped or replacement nodes formed. This will occur the following year after pruning.

If only certain areas have been affected on the vine, they should be carefully cut off. The main thing is not to panic and remember that the vineyard can be restored and harvested in the same season.

If the flow of grape juice has not yet been used, treat the gnawed areas with a garden planter. Do this very carefully to avoid damaging the affected branches even more.

The most affected vines can be supported by tying rubber with insulating tape or wire.

How to prevent?

Grapes and mouse

Many gardeners spray bushes for prevention to prevent plants from drying out for the winter:

These folk remedies require almost no effort, but their effectiveness is not as high.

You can sprinkle rodent poison, but this method is not ideal and does not prevent the invasion of large numbers of mice.

Ultrasonic rodent and mole repellents are more effective than poisons. When choosing, however, you should familiarize yourself with the ratings of the model, as they vary greatly.

However, you will achieve the greatest effectiveness only if you combine several methods. With a set of measures, you will get rid of uninvited gray guests once and for all.

There are several simple methods to protect your vineyard from mice. You can use ordinary polyethylene film, which is available in every home. By surrounding the vine, it makes it difficult for rodents to access. But it must be removed in time, when they get established, otherwise rotting will begin.

There are more effective methods:

  1. Bring the vineyard down into a level ditch. Backfill it with small branches, needles or leaves. This method mechanically prevents rodents from getting into the grapes.
  2. Cover the roots of the bushes with black root or spruce branches. Black root (black root) is popularly called “rat root” as it has proven to have an effect on rodents.
  3. It is very effective for summer time to plant the vineyard area with dandelions. This is a popular mouse treat, and it distracts gray guests from the grapes.
  4. Waterfalls are easy to make out of plastic bottles. To do this, cut off the neck, dig the container next to the grapevine and place an edible bait at the bottom. To enhance the smell, pour sunflower oil on the food. Such a trap is very tempting for the mouse.
  5. Be sure to use a covering material to mechanically protect the vine. Do this only after the beginning of frost, otherwise the vine will begin to rot.


Special chemical preparations are more effective in the fight against rodents than folk remedies and improvised means. However, it is very important to follow the instructions on the website, so as not to harm plants, animals and people.

The most popular poison for mice:

  • Flocumem;
  • Brodifacoum;
  • Diphenacin.

The vast majority of chemicals contain not only poison, but also components that attract rodents. These can be flours, flavorings. The main purpose of these additives is to let the mice eat the poison.

Be afraid of scents.

You can protect your vineyard with scents:

  • Kerosene;
  • Naphthalene;
  • tar;
  • liquid smoke;
  • VICTORY ointment.

The source of fragrance covers the vine, impregnating the cover material on the roots of the plant. It is very important to renew the fragrance in a timely manner, as it fades quickly.
