Efficiency
According to reviews from gardeners and gardeners, it is impossible to free the area from ants at one time. But, thanks to Thunder-2, it is possible to significantly reduce their number (the effect is observed after 2-4 days). When using granules against pests that live underground, the duration of action of the insecticide is 2-3 months. The active substance helps to destroy not only adults, but also larvae.
Thanks to aromatic additives, the product quickly attracts insects. To get rid of fungus gnats, granules are embedded in shallow grooves around the plants. After 3-5 days, a significant decrease in the number of pests is observed. Since the microgranules are effective for more than two months, the insecticide can be used once per season.
Advantages and disadvantages
The disadvantage of the drug is its danger to the inhabitants of water bodies. It is necessary to ensure that during treatment, even a small amount of granules does not fall into lakes or rivers, since they are poisonous to fish, frogs, etc. For the same reason, the insecticide should not be allowed to enter the aquarium. The product is dangerous for birds, so the granules should be stored away from ducks, chickens, and geese.
The benefits of the product include:
- Safety for earthworms and other soil inhabitants.
- Safety for plants, flowers and fruits.
- Safety for people and animals subject to direct contact.
- Thunder 2 allows you to quickly get rid of ants, fungus gnat larvae, and mole crickets.
- A long period of protective action, which is 2-3 months.
- Easy to use.

Purpose and principle of operation
Preparations based on diazinon are used for spraying crops to destroy pests that chew or suck:
- aphids, cutworms;
- cabbage fly;
- wireworm in corn plantings;
- bugs, weevils on seed alfalfa;
- flea beetles, aphids, weevils on beets.
When released into the soil, the drug “Grom-2” is absorbed by the root system of plants. Distributed over the above-ground parts of plant crops, the drug provides protection against midges and other insects. Diazinon disrupts the functioning of the nervous system of insect pests, provokes the development of paralysis and leads to death.

general characteristics
“Thunder” from the mole cricket is a Russian-made insecticide, and its name sounds intimidating. It appeared from adding the first letters of the phrase “pellets from mole crickets.” The main active ingredient is diazinon, 30 g of which is contained in each kilogram of the drug. In addition, the product contains 8 food components. Their purpose is to make the poison very attractive to crayfish.
The pests liked this delicacy; they prefer the deadly granules to the roots and leaves of plants.
After consuming the bait, 92 to 100 percent of mole crickets and their larvae die. This is the highest figure among similar drugs used to control soil pests.
The drug does not have a contact effect, so the mole cricket does not die immediately after applying the insecticide to the soil. To do this, diazinon must enter the digestive system of insects, after which it will completely block the function of digesting food, which will lead to the death of the pest within three to five days. After application to the soil, “Grom” retains its properties for 2 weeks.
