    I combat them using 1.25ml dimethoate diluted in 1L of water and spray the affected plant with an atomizer, it also charges all kinds of aphids and thrips, soap foam also works but the stain remains on the plant or garlic curing ( 1 head of garlic and 3 cigarettes in 1L of alcohol, it rests for 1 week) the affected plant is sprayed with that, kills aphids, mealybugs and drives away the ants that raise them as cattle and even smells rich XD

    Good morning, I have ball bugs in the house, I need to know how to eliminate them, I usually find them under the counter in the kitchen and near the washing machine in the bathroom; I moved in two months ago.

    Outside I have almost no plants, I am just putting together the garden, and from what I saw, in the few plants that I have there are none.

      Ball bugs are in principle not dangerous to plants.
