Neem Oil Insecticide

Neem Oil Insecticide contains a variety of compounds which can act as an effective insecticide in your garden. Unlike toxic chemical insecticides, the compounds of neem act on the insect’s hormonal system, disrupting the insects reproductive cycle.

‘Limonoids’ from Neem Block Insect Growth

Neem compounds called ‘limonoids’ make it a effective insecticide, pesticide and fungicide. The most significant liminoids found in neem with proven ability to block insect growth are: azadirachtin, salanin, meliantriol and nimbin. Azadirachtin is currently considered as neem’s main agent for controlling insects. It appears to cause 90% of the effect on most pests.

It does not kill insects immediately – instead it both repels and disrupts their growth and reproduction. Research over the past years has shown that it will repel or reduce the feeding of many species of pest insects as well as some nematodes. In fact, it is so potent that a mere trace of its presence prevents some insects from even touching plants.

Azadirachtin Deters Insect Reproduction

Certain hormones are necessary for growth and development of insects. These hormones control the process of metamorphosis as the insects pass from larva to pupa to adult. Azadirachtin blocks those parts of the insect’s brain that produce these vital hormones. As a result, insects are unable to molt. It is through these subtle hormonal effects that this important compound of neem breaks the life cycle of insects. The insect populations decline drastically as they become unable to reproduce.

Neem oil insecticides can deter insects in the following ways:

• Disrupting the development of eggs, larvae or pupae.
• Blocking the molting of larvae or nymphs
• Disrupting mating and sexual communication
• Repelling or poisoning larvae and adults
• Sterilizing adults
• Deterring feeding
• Sending metamorphosis awry at various stages

Neem Oil Insecticides are generally harmless to most insect eaters, humans and other mammals, with the exception of certain marine life such as crabs, lobsters, fishes and tadpoles.
