Mole cricket (cabbage weed, crayfish, crayfish) belongs to the group of dangerous pests of agricultural crops. A voracious and prolific insect causes serious damage to plantings, damaging roots, root crops, and young plant shoots.

Despite the huge number of means, methods of destroying and repelling the pest, it is not always possible to achieve the desired result. Therefore, gardeners are always looking for: how to deal with mole crickets, what technology is effective, and at the same time as safe as possible for humans.

  • Features of pest control

    The mole cricket on the site lives in the soil, arranging numerous burrows, nesting places, and storerooms underground. It rarely appears on the surface, quickly runs away from danger, flies, swims quickly, which seriously complicates the fight (see photo of the mole cricket).

    It prefers garden plots with manured, moist soil, vigilantly standing guard over its possessions, protecting nests with clutches of eggs and larvae.

    To destroy the pest in a summer cottage, various methods and technologies are used. A number of means are used to repel cabbage grass, others are used to exterminate and reduce the population. In the list of funds:

    • traps;
    • bait;
    • electronic and homemade repellers;
    • insecticides;
    • biological drugs;
    • compositions according to folk recipes;
    • mechanical methods.

    There is no single effective method of control; it is advisable to take an integrated approach using various means. The use of folk recipes gives results as a preventive measure, as well as with a small number of insects on the site. If there is a massive pest invasion, then “chemistry” has to be used. It is difficult to get rid of mole crickets in the garden forever, but for some period of time it is quite achievable.

    On a note! To destroy the mole cricket, you need to involve your neighbors in the country. Only through joint efforts will it be possible to cope with a serious “enemy”.

    Damage to mole crickets in the garden

    The mole cricket (cabbage moth) looks extremely unattractive, but a much greater danger is the damage that the insect causes to garden crops. If cabbage weed has been spotted on your site, it is imperative to combat it, since the insect will definitely lay eggs, from which larvae will later hatch and the pest population will increase significantly, and with it a danger to garden crops.

    Note: One adult can gnaw on the roots of more than 10 plants per day, which will invariably lead to a decrease in yield. Insect larvae that appear at the end of summer only enhance the negative effect.

    Adults and larvae dig deep passages and tunnels in the ground, in the process gnawing the roots of any plants encountered along their path. Most often, the pest is found on cucumber plantings, but absolutely any plant can be damaged by insect activity (Figure 7).


    Figure 7. External features of the pest

    If a mole cricket has damaged a young plant, it will be greatly weakened and pulling it out of the soil will not be difficult. If already mature and mature specimens are damaged, diseases and a decrease in yield may appear.

    Cabbage weed is especially dangerous for potatoes and root vegetables. The insect eats the pulp of such vegetables. As a result, large cavities form in the root crops, which reduces their marketability and does not allow the crop to be stored for long-term storage. It is no less dangerous for the garden. Despite the fact that this pest is not capable of gnawing the roots of adult plants, it can significantly damage the root system of young seedlings of fruit and berry and ornamental crops.

    The use of folk remedies

    Gardeners have accumulated a wealth of experience in various means of exterminating and repelling cabbage grass. Some of them are unusual, others are traditional, known to summer residents of various regions.

    They save themselves from the voracious earth mole with the help of birch tar and ammonia, onion peels and crushed eggshells. As assistants for summer residents:

    • garlic;
    • coniferous branches;
    • kerosene;
    • matches;
    • chicken droppings;
    • laundry and tar soap, shampoo;
    • naphthalene;
    • iodine;
    • turpentine.

    When using the products, we must remember that thoughtlessly watering the beds with kerosene or laying out large quantities of naphthalene will lead to contamination of the area and deterioration of the quality of the soil.

    The effectiveness of each method is tested in practice, and in any case it is necessary to approach folk recipes and recommendations wisely and without excessive fanaticism.

    Setting up traps

    To exterminate insects, traps are built in gardens and garden plots, luring mole crickets with honey, beer, and fermented jam. The basis of the traps are containers (plastic bottles, glass or tin cans) buried in depressions in the soil. A little beer or other bait is poured into them and covered with a board or piece of tarpaulin on top.

    Holes are dug in places where the pest is expected to live, and traps are checked every 10-15 days.

    Terradox

    The remedy for mole cricket Terradox is an insecticide with a prolonged effect. It is used to protect vegetable, berry crops, and fruit seedlings from pests. Characteristics of the chemical:

    Lures

    In a summer cottage, it is easy to make baits to kill crayfish using different grains. Poison (boric acid, insecticides) is added to cereals as active ingredients.

    Several recipes:

    • steamed grain (corn, wheat) + Metaphos;
    • steamed peas (1-1.5 kg) + Regent preparation (ampoule);
    • 0.5-1 kg of porridge (buckwheat, pearl barley, oatmeal) + Parachute (ampoule);
    • crumb of black bread + sulfur of matches.

    Baits are scattered between rows in beds, under plants, and placed in pest holes.

    On a note! To attract mole crickets for scent, add a couple of tablespoons of unrefined vegetable oil to porridge or steamed grain.

    Such baits must be used carefully, keeping domestic animals, chickens, geese, and ducks away from the area.

    Boverin

    A new generation insecticide, Boverin, is a biological product. By adding it to the soil of a site, you can simultaneously get rid of several types of insect pests. Characteristics of Boverin:

    • Release form: liquid or light powder.
    • Active ingredient: spores of the fungus Beauveria bassiana, located in the nutrient substrate. When ingested by a parasite, they begin to grow and cause the death of the insect.
    • Duration of action: fungal colonies continue to grow in moist soil even after the death of the pest, so their action is active throughout the warm season.
    • When to use: the optimal time for the growth of a colony of Boverin fungi is spring-autumn, when the ambient temperature is in the range - + 18-28 ° C with a humidity of 80-85%!
    • Directions for use: add 2 tbsp to 200 g of the drug. spoons of vegetable oil and stir until smooth. Spread the resulting mass into holes and row spacing to a depth of 2–10 cm. Product consumption is 200 g per 100 m².
    • Toxicity: Boverin is not toxic, but all manipulations with fungal spores must be carried out using personal protective equipment (gloves and a respirator) to prevent them from entering the human body.
    • Price: 200 g – about 50 rubles.

    Plants are protectors

    It has been noticed that some strong-smelling herbs and flowers repel cabbageweed. The insect has a well-developed sense of smell; foreign specific odors depress and disturb the pest. This is used by summer residents who plant marigolds and chrysanthemums around the perimeter of the beds.

    The mole cricket cannot stand the smell of aspen, but in this case they do without planting trees. Prepare aspen branches or pegs and stick them into different places in the garden. It has been tested that the pest soon leaves uncomfortable places, preferring to breed in favorable conditions.

    What do affected plants look like?

    Mole crickets feed on the roots and stems of vegetable crops and damage young shrubs, grasses, and bulbous flowers. When examining the plants, it appears that someone has cut the stems. In beds with carrots or beets, all the tops lie on the ground, as if a scythe had been passed over it. Marks remain on root vegetables and flower bulbs: the mole cricket completely gnaws through them, leaving behind voids. As a result, such vegetables are no longer suitable for further use.


    Reasons for the appearance of pests: 1. Use of fresh organic matter as fertilizers. Moreover, this way pests can spread from neighboring gardens. 2. The insect overwinters in manure heaps and compost pits, and then is introduced into the soil. 3. Waterlogging of mulched areas or close proximity to groundwater. The moisture does not have time to evaporate, and the soil remains constantly wet. This environment is ideal for mole crickets.

    Natural enemies of cabbage grass

    Birds are not averse to feasting on insects: rooks, starlings, crows. In the southern regions, storks actively exterminate cabbageweed; the main thing is to attract the insect’s natural enemies to the site.

    To do this, they build birdhouses, feed the birds, and do not destroy the nests.

    Hedgehogs will help reduce the population of earthen crayfish. For these useful animals, secluded places are arranged in areas (in lowlands, near rotten trees, near hedges). Another group of helpers are ground beetles, lizards, shrews, and centipedes.

    A species of burrowing wasp, Larra anathema, poses a serious danger to cabbageweed. The solitary black wasp is known for its care of offspring and its original way of laying eggs. She chooses a mole cricket for the nest, looking for insects in the underground labyrinths of burrows. Drives the pest to the surface, stings, causing temporary paralysis and during this time manages to lay one egg under the insect’s foot.

    After some time, the mole cricket comes to life, crawls into its hole, and the sand wasp larva successfully develops, parasitizing on the body of the insect. Shortly before the wasp pupates (approximately 15-30 days after laying), the mole cricket dies. This is how the Larra wasp helps a person fight a dangerous pest.

    Terradox

    Rating: 4.4

    In sixth place in the ranking is a drug that affects all harmful soil insects. It is used to protect potatoes, tomatoes, cucumbers, berries, coniferous and deciduous trees, and ornamental crops, providing reliable protection and accelerating their growth. The product belongs to a low toxicity class. Humans, animals, birds, earthworms are out of the risk zone.

    Biological drugs: is it worth using?

    Nowadays, biological products that are considered environmentally friendly are actively used in pest control. Another “advantage” of such products is the lack of resistance in insects, which is often noted with traditional insecticides.

    Operating principle: colonization of the pest’s body by fungi or predatory insects that parasitize at the expense of the host (mole cricket, wireworm).

    The following remedies will help you get rid of mole crickets:

    • Nemabact is a symbiosis of bacteria and a certain subspecies of nematode. The predator is distinguished by its reproduction speed, when used it gives an effect of up to 70-80%;
    • Antonem-F is a drug similar to Nemabact, differing only in the type of nematode;
    • Boverine is a drug based on the spores of a fungus of the Deuteromycetes species, which causes the disease muscardinosis. The peculiarity of the action is germination in the body of the mole cricket, poisoning of larvae and adults, infection of insects in the entire population.

    But the use of biological agents is associated with difficulties:

    • effective only at certain soil moisture and temperature levels;
    • The preparation of biological products requires strict adherence to the recipe and deadlines.

    Description of the insect and the damage caused

    The mole cricket is a dark brown insect. The length of the body is 5–8 cm. The pest has a gnawing type jaw apparatus. The body of the mole cricket is covered with a hard shell. At the base of the insect's cephalothorax are digging legs. Thanks to them, the mole cricket moves underground.

    At the end of the pest's abdomen are thread-like appendages. The front claws are well suited for digging in the soft soil of beds and agricultural fields. The activity of the insect depends on the time of year and the state of the environment. The peak of the harmful activity of the mole cricket occurs in the summer. The insect is omnivorous.

    The mole cricket absorbs the root part of cultivated plants and leaf mass. By digging through winding underground passages, it sprinkles soil on the seedlings, which leads to suppression of their vital activity and death. Owners of dachas and vegetable gardens are trying to get rid of mole crickets forever in order to ensure good productivity of their plots.

    Repelling mole crickets

    Simple but effective repelling methods include the installation of special devices (turntables, electronic devices).

    On a note! Widely advertised ultrasonic devices are not suitable for repelling mole crickets and moles. Digging species of animals and insects do not perceive ultrasound, so repellers with infosound (oscillations at low frequencies) are used for them.

    There are various models of devices on sale that operate at radii from 400 to 1500 meters.

    Craftsmen make turntables with blades in their summer cottages using ordinary plastic bottles. Placed on stakes, such weather vanes rotate in the wind, creating vibration in the surface layers of the soil. This scares away the cabbage grass, and the pest leaves the area.

    Chops

    An effective, brightly colored granular insecticide designed to kill pests living in the soil. These include mole crickets, beetleworm larvae, and wireworms.

    Release form

    This medicine for mole crickets consists of red and green granules placed in waterproof bags. Weight - 100 g.

    Chemical composition

    The main substance is malathion 50 g/kg.

    Mechanism of action Once in the insect's body, malathion is converted into a physiologically active substance with a very high toxic ability.

    With frequent use of the product, insects begin to develop resistance to malathion . The body of such pests develops the ability to destroy the chemical, turning it into a non-toxic compound.

    Duration of action

    Death occurs 3 hours after the drug enters the mole cricket’s body. The duration of toxic activity is up to 20 days after placement in the ground.

    Compatibility with other drugs

    Malathion, among other organophosphorus compounds, combines well with most known insecticides and fungicides.

    When to use?

    The first laying of granules is carried out 8-10 days before planting seedlings and sowing seeds in moist soil. It is advisable to carry out the procedure after rain or shortly before it starts.

    Mode of application

    The poison from the mole cricket is placed in grooves or holes up to 5 cm deep , placing Rubit in the places most often visited by the mole cricket - heaps of manure and compost, beds and holes, row spacing, tree trunk circles. The granules are covered with earth on top. The consumption rate is 6-10 g every half meter.

    Toxicity

    Rubit is a moderately toxic product and belongs to class 3 hazard for people , mammals and birds.

    The mole cricket is extremely voracious and she doesn’t care at all about how much work and effort we put into our dacha affairs. Read the advice of our experts on effective methods of combating this insect, including folk remedies.

    Features of the use of insecticides

    In case of mass pest invasions, there is no other way but to use “chemistry”. Not every summer resident agrees to use insecticides, but faced with the threat of crop loss, one has to make a choice.

    The list of chemicals includes both universal remedies for garden pests and specialized ones (only for mole crickets). Approved medications are used, strictly observing processing times, dosages, and protective measures during work.

    It is necessary to follow the instructions regarding the time intervals between the procedure and harvesting (waiting periods), take into account the hazard class of the insecticide (for humans, for bees, for inhabitants of water bodies). The permitted frequency of treatments is also indicated in the instructions.

    Among the popular remedies among summer residents, we note:

    • chops;
    • Thunder;
    • Parachute;
    • Frontier;
    • Grizzly;
    • Wofatox.

    The use of these chemical insecticides is described in detail in articles on our website.

    Other modern insecticides (concentrates, granules, powders) are also used in the fight against mole crickets (see table).

    In addition to treating plantings, insecticides are added to baits as poisons.

    Seedling protection

    In farms where crops are grown over large areas, seedling treatment technology is used to protect against mole crickets. The most commonly used solution is the insecticide Aktara, known to gardeners as a remedy against the Colorado potato beetle on potatoes, tomatoes, aphids, and thrips.

    On a note! The manufacturer of Aktara is Singenta. It is advisable to purchase the insecticide in the manufacturer's original packaging.

    For treatment, prepare an aqueous solution (take 15 grams of Aktara per 10 liters of water), soak the roots of the seedlings for 1-1.5 hours, then plant them in a permanent place in greenhouses or on ridges without washing. From experience, the mole cricket is careful not to attack such plants, so the seedlings adapt well and grow quickly.

    We are expanding the range of drugs

    In addition to traditional insecticides designed to combat mole crickets, gardeners have recently been using other preparations. This is due to the fact that insects become accustomed to certain types of chemicals, which reduces their effectiveness.

    For baits (adding steamed grain or peas to porridge), use Regent 800 in granules, as well as liquid concentrate Regent 25. These fipronil-based products have gained popularity in the fight against the Colorado potato beetle, but summer residents also successfully use them to protect plantings from cabbage weed. .

    Security measures

    Potent synthetic compounds designed to combat harmful insects require compliance with certain safety rules.

    When carrying out disinfestation:

    1. Wear a suit made of thick rubberized material.
    2. To protect the eyes and respiratory tract, use sealed goggles and a gauze bandage or respirator.
    3. Pesticides dissolved in organic liquids can cause burns and allergic reactions upon contact with the skin. To work with them, wear closed overalls.
    4. Solutions are prepared in the fresh air or in a well-ventilated area.
    5. When treating crops with such potent chemicals as Fastak, take breaks every half hour.

    At the end of the disinfestation procedure, take a warm shower. Chemical protective equipment is not brought into residential premises.
