After the end of the summer season, the pests burrow into the soil, where they wait for warmth and new plantings.
As soon as the soil warms up to approximately +15 °C, the Colorado potato beetle becomes active again.
Some summer residents do not like or do not accept chemicals as the main measure for pest control.
Often this category wants to grow environmentally friendly vegetables, without harmful chemicals and other components that can affect health.
Such gardeners try to cope with folk remedies, which allow them to achieve the desired result without the use of special preparations.
Moreover, it is known that beetles get used to a certain product in 2-3 seasons, so the pest has to be poisoned with a different composition.
Experienced gardeners have noticed that the Colorado potato beetle hates the smell of walnuts. On its basis, gardeners prepare an infusion, which is a real poison for the pest.
Take the shell and dried leaves of the nut - 300-350 g per 10 liters of water. They are pre-crushed and then filled with liquid.
The solution is infused for 5 days, then filtered, poured into a spray bottle and sprayed.
