Not all bugs that approach your plants are harmful. Some even help your plants grow by pollinating or even feeding on insects that are harmful to your plants.
However, this does not mean that you should not take action when you find aphids on your pods, but you can spray your plants with a homemade insecticide.
Natural insecticides are pest selective, i.e. there is not a single natural insecticide for all pests, but there are different compositions depending on the pest to be treated. Thanks to this, we can reduce the potential damage to non-target species mentioned before, such as pollinators and other beneficial insects.
