Beneficial Insect For Corn – Pest Control

For years, in the garden, I struggled with earworms in my corn. Those are the nasty larva, of certain moths, that eat away the ends of the corn and grow into bigger and bigger worms. I hate them. They gross me out when I am trying to shuck the corn.

A few years ago I found a natural predator for these worms at the Planet Natural online store. They are called, Trichogramma wasps, and are tiny parasitic wasps that destroy the eggs of the corn worm moth. This prevents having to treat the corn with chemicals. It also saves time, since all you have to do is walk out to the garden and place the cups containing the wasps in your corn patch.

There is a natural timing to the cycles of these pests,  and I have found if I purchase the wasps when the corn in about 2 inches higher than shown in this picture…..

I have ten rows of corn. These are the longest rows.

The corn needs to be about knee high when you order and release these beneficial insects.

… the wasps arrive at the perfect time to break into the moth’s cycle and take care of business.

The wasps come in egg form, attached to little pieces of what looks like sandpaper. You place them around the garden in shady spots and away from ants, because ants are their predator. When they come, many of the eggs have already hatched and you can just barely see them crawling around in the little plastic cups that they arrive in.

So… if you want to have a chemical free pest control for corn, this is it. Planet Natural also has a wide array of other beneficial insects you may want to try for other problem areas.

I am on a new mission to find references in the Bible to everything I deal with in life, even the small things.


here goes…..

“And the Lord God prepared a gourd, and made it to come up over Jonah, that it might be a shadow over his head, to deliver him from his grief. So Jonah was exceeding glad of the gourd. But God prepared a worm when the morning rose the next day, and it smote the gourd, that it withered.” Jonah 4:6-7

Too bad Jonah didn’t know about Trichogramma wasps! 🙂
