Organic insecticide, products on the market

Neem oil, as well as pyrethrum, are two completely natural compounds, highly appreciated in organic farming.

Neem oil

L'Neem oilcan be used asnatural pesticideto be applied for the care of ornamental plants both indoors and outdoors. This particular natural product is obtained from the Indian "sacred tree" Neem and is a powerful natural pesticide that acts on the reproductive system of the parasite, preventing it from multiplying. The Neem tree extract allows a healthy approach to the control of infestations because it intervenes with great effectiveness on reproduction and not with the direct killing of the animal. The bodies of insects absorb theNeem oil and their endocrine system is blocked, in other words they become sterile and cannot reproduce.

Being anatural pesticideit is possible to apply it once a week even as a precaution only. In case of infestation already in progress, it will be necessary to proceed with an application for 2 consecutive days and resume the weekly applications after 3 days. A single pack ofNeem oil it lasts a long time as it is used diluted: a single teaspoon per 1 liter of warm water to be sprayed abundantly directly on the plant, especially on the underside of the leaves.

A bat devours up to 2000 insects per night. Very convenient for those who have a garden or a small artificial pond which leads to the development of dipteran larvae. The bat box indicated in the link above is an artisanal product (handmade) and is made in Italy; is made with marine plywood. The bat nest is delivered already assembled and with a coat of ecological transparent varnish; for each cassette purchased, the manufacturer will donate € 1 to Lipu.
