Chemical pesticides are the best way to get rid of them but they back up cancerous activity and are detrimental to the environment, that is why using natural pesticides for the garden are the safest and best option as they are inexpensive and Eco-friendly.

1. Neem Oil

Neem Oil is among the most powerful natural pesticides and insecticides; it covers more than 200 species of chewing and sucking insects. It’s completely nontoxic and does not have any adverse effect on plants if used accordingly.

Take one-liter warm water and mix a half teaspoon of insecticidal soap. Stirring vigorously mix one teaspoon of neem oil in it. Fill it in a sprayer.

  • Always wear gloves and eyeglass, when dealing with pepper and Neem.
  • Avoid spraying plants on windy days, spray in late afternoon or evening for better results.
  • Don’t use a dish soap that contains bleach.
  • Make sure to spray the underside of leaves because it is pest favorite place to hide.

  1. HELP!! JapanesebBeetles are eating my roses and Crrpe Myrtle buds. I hand pick 100’s and kill them by dropping them in soapy water; however, I kill 1 hundred and 300 hatch out! I’m fighting a loosing battle but I can’t give up. Out of desperation I sprayed with a strong solution of Spectracide and cried when I saw all the dead “good guys”!…, that is not an option.

    Is there any help for my nightmare??

    • I don’t know how big your Crepe Myrtle is, but if practical, you could try Diatomaceous Earth. It’s a powder-type substance that consists of ancient fossilised shells (I think?) that have sharp edges on all sides. The way it works is that when a insect crawls over the powder, they are sort of injured in that their soft body or even the hard shell will be pierced or sliced. This allows crucial moisture to leave their bodies, leading to dehydration and death. Apparently it will affect the adults as well as the young, but even if only effective on soft-bodied new crawlers, eventually your infestation will have to end because no more hatchings means no more adults. Pretty sure it does effect the adults too, though.

      IMPORTANT!!!: MAKE SURE YOU BUY DIATOMACEOUS EARTH AT THE GARDEN NURSERY. THERE’S ALSO A KIND OF DM USED IN POOL FILTERS THAT IS NOT SUITABLE FOR PEST CONTROL (might have chemical component you don’t want in the garden) Diatomaceous Earth in pure form is acceptable for Organic Methods used in Vegetable Garden. Probably not a bad idea to waer a dust mask and eye protection while in use. You probably could just put a little in the crotches of the branches, and eventually the bugs will have to crawl around in it; if most of the activity seems to be on the leaves, put the DM there. You don’t need to create a huge cloud of powder around your tree for it to be effective. GOOD LUCK!

  2. I just spent a whole month picking the beetles off by hand. Unfortunately that is the safest way to get rid of them for the environment. Also I save and crush eggshells in my food processor to use as the diamatious earth substitute. They don’t like to walk on it. Also a weak solution of cinammon and water also helps. Then after all that they just disappeared. They had been attacking my crepe myrtle and fruit trees and also my wild roses. Good luck with those beasts!!!!

  3. I have to admit that this one is new to me, but I ve seen enough mentions of it now to warrant its inclusion here as a natural pesticide. Tomato plants are part of the nightshade family, and as such, contain alkaloids such as the aptly named tomatine, which can effectively control aphids and other insects. ? ? To make tomato leaf spray for a natural insecticide, chop two cups of fresh tomato leaves (which can be taken from the bottom part of the plant) into one quart of water, and let steep overnight. Strain out the plant material and spray onto plant foliage.

  4. My lemon tree is in a pot, the first time it produce 5 lemons, the lemons remain very small, started to turn yellow and drop off the tree, the lemon tree is four years old. I give the it citrus fertilizer. I’m from Barbados, a very warm climate.
