When it comes to insecticides, they can be organic with plant-derived active ingredients, like pyrethrin and neem oil, or synthetic pesticides.

While birds feeding on these pests and wasps parasitizing their eggs is helpful, this is certainly no substitute for sustainable pest control.

What is the best insecticide for caterpillars?

Since it is recommended as a solution against young pests, take care to use B.t. with the first signs of the damage, otherwise, it may be too late for this type of control. Scientists from the University of Minnesota Extension point out that B.t. targets specifically caterpillars and the pest has to eat the substance to be killed by the bacterium. Therefore, to obtain a result, you should treat the area thoroughly to make sure that the bacteria is in abundance in the soil. The downside of this active ingredient is in its short residual.
