The use of neem oil insecticide is very popular in certain parts of the world, particularly the Indian subcontinent, where neem is such a cultural staple.
Is Neem Oil Effective Against Insects?
Neem oil is highly effective against insects, but unlike many other insecticides and pesticides, the effects are not immediate. Neem is a highly valued plant in many cultures around the world and is not known for its toxicity in humans. This leads to many people doubting the efficacy of this oil against insects. That being said, the effects of this oil on insects is quite unique; the impact that it can have on hormones will disrupt normal pathways in their brains. This may result in their inability to eat, mate or perform other basic processes necessary for survival. Therefore, extended exposure to this oil will gradually decrease your insect infestation, without damaging the crops, other animals, children or end-consumers of crops and products. Additionally, neem oil has a powerful scent that many insects find unappealing, causing them to avoid the areas with that scent.
This delayed effect of neem oil is particularly good for eliminating sucking and chewing insects, which are common pests for agriculture. Many farmers dismiss the efficacy of this oil, but with a bit of patience, you can enjoy a side effects-free method of cutting down on your insect problem.
