1. It works!
Tests conducted by researchers around the world show that neem oil controls more than 200 insect pests. (Check out Neem: A Tree for Solving Global Problems, published by the National Academy Press or the National Institutes of Health at www.pubmed.com for more information.)
2. NimBioSys neem oil is EPA-registered to control what most of us recognize as the worst pests on our plants:
· Aphids
· Beetles
· Stink Bugs
· Caterpillars
· Leafhoppers
· Leafminers
· Mealy Bugs
· Midges
· Mites (especially spider mites, particularly if you catch them early and use neem as a soil drench)
· Nematodes (also when used as a soil drench)
· Scale
· Thrips
· Weevils
· Whiteflies
3. Neem oil is less toxic than aspirin or salt.
In fact, it’s so non-toxic that we sell more neem oil in skincare products than we do as a pesticide. Our lotion has 10 times as much neem oil than we recommend that you use to spray your vegetables. That’s a really nice feeling when you’re spraying vegetables and the wind shifts. You get a face full of neem oil — not malathion!
And ongoing studies show that it’s safe for bees and other beneficial insects that aren’t eating your plants unless you drown them in oily water. (It does kill caterpillars though so don’t spray it on larval food for butterflies.)

Important Note:
Many people who tried neem oil purchased in a “big box” garden center haven’t been particularly impressed with the results. That’s because they bought clarified hydrophobic extract of neem oil — which is neem oil with the azadirachtin removed. Since azadirachtin is the most important compound for controlling insects, the hydrophobic extract is nowhere near as effective as a full-spectrum cold-pressed neem oil like NimBioSys.
And from a sustainable perspective, the “inert” ingredients in those big-box brands may also not be the best choices for our planet. At least one inert ingredient has been implicated in killing bees in California (https://www.scientificamerican.com/podcast/episode/pesticide-additive-could-be-one-culprit-in-bee-deaths/?WT.mc_id=SA_ENGYSUS_20170126)

Hi, please tell me how to use your product. Is it to be diluted? At what rate? Does one use a wetting agent or surfactant in order to spray? How much product can I expect to get when diluted?
I’d order today but I’d like more info than your website provides.
Hi Roy,
There are all kinds of ways to use neem oil, here are our recommendations: https://neemtreefarms.com/neem-soap-emulsifier/
Thanks for asking!
Hi R:
I thought I had answered this earlier. Here’s how we use neem: https://neemtreefarms.com/neem-soap-emulsifier/

I grew 3 neem from your seeds do I need to pinch cut the tops of to get them to branch out they are a single trunk? They are approximately 4 and 3.5 feet tall and one thats two feet tall. The two young trees i purchased are doing wonderfully fully branched out so I am wondering what I am doing wrong. Thank you for making these lovely trees available.
Hi Karen,
Neem needs to be cut back, and probably cut back often. The trees you purchased from us almost certainly had been cut back at least once. Here’s a blog on how to prune your trees. If you’re far north and not far off from freezing temperatures, just trim a little bit now and then plan on chopping off the top of the trees in the spring.

Does neem tree grow in cold climates?
No, I’m sorry it doesn’t. You can grow it in a pot for use as a medicinal herb, but not enough to use on a vegetable garden.
Hi! Can I use this with a hose spreader for my yard? If so, how would I do this?
Also, my Doodles are in love with the Neem Chews 🥰
Good news and bad news..
Neem oil doesn’t work in a hose-end sprayer, it needs a lot more surfactant than we’ve been able to identify to stay emulsified.
The good news is that neem, taken internally, appears to boost my pups’ immune systems to the point where fleas just don’t make it. You’ll want to use the ground neem bark on their food so you know how much they’re getting. The general recommendation is 1/8 teaspoon per 10 pounds, so my 50-pound Shar-Pei rescues get a heaping half-teaspoon.
