Soapy Water, Neem Oil and a copy of Good Bug Bad Bug by Jessica Walliser will take you far in your fight against bad bugs. It is important to know that in the garden, all bugs aren’t bad. Experienced gardeners love bugs (as long as they’re the good kind) because they know beneficial insects are an effective natural solution to garden pests. Jessica's book has taught me a lot about who is who (good and bad) in my garden and it is a reference I frequently consult.
In the case of my tomato worms I have to admit, I didn't yet own a copy Good Bug Bad Bug. If I had I would have spared myself the gagging torture of hand picking off every tomato worm I found (something about the marshmallow squishy texture of hornworms makes me want to vomit). It was fully a season later that I bought the book and learned that my efforts of hand picking probably had less to do with my successful eradication than the fact that they had little white sacs hanging off them. I assumed the sacs where an army of baby hornworms in waiting, but in fact, they were the cocoons of beneficial parasitic wasps. The wasp larvae in these sacs kill the worms and grow into wasps who will lay eggs on future hornworms. I clearly have a good natural cycle going because I haven't had tomato worm trouble since.
Soapy water (an easy mix of your favorite dish soap and water) will kill 90% of bugs you find. Make sure that the bugs you have are not beneficial first and if not, you can either spray the pests with the solution or carry a cup full around the garden. As you encounter trouble makers, flick them off your plants and into the cup where they will perish.
Neem oil which is made from the seeds of the tropical neem tree is an all purpose organic pesticide. It repels insects, preventing a problem before it starts, as well as suppresses feeding and molting, interrupting their lifecycle. During the winter, I spray my indoor plants with a light mix of of Neem oil and soapy water as a preventative measure and in the summer I carry on outdoors as needed.
Year of practice and experimentation have taught me a lot, but I still have some mysteries....like how do the wasps find the hornworms? I have no idea.
Do you have any handy organic gardening tricks to share?
