Cornmeal as Ant and Weed Control
Looking for something organic for ant control around your home or in your
gardens? Has crabgrass invaded your lawn, and you're seeking an environmentally
friendly way to treat your lawn. Cornmeal is the answer!
Researchers at Iowa State University discovered that cornmeal, a by product
of corn wet milling, can control ants, and is an effective pre-emergence
crabgrass preventer. Commonly called Corn Gluten Meal (CGM), it sure
beats the environmentally harmful herbicides you've been putting on your
lawn every spring. It is also used to feed cattle, fish, and poultry..
In the lawn and garden, cornmeal prevents crabgrass, dandelion, chickweed
and some other weeds from sprouting. It is important to note, like chemical
pre-emergence herbicides, cornmeal is only effective on weed seeds, keeping
them from sprouting. It is applied before the seeds have sprouted and the
plant begins to grow. It is not effective against weed plants after that
Important Garden Note: Do not use cornmeal in the garden when planting
seeds, until after the plants have sprouted. It can keep some garden seeds
Apply cornmeal in your lawn in early spring. Follow the instruction on the
packaging for the most effective use of this organic product.
For controlling ants, spread cornmeal around the outside of your home for
safe and effective control. The ants take it back to their nests. They can
not digest cornmeal.
Apply cornmeal every 4 weeks, or after a heavy rain.
Did You Know? Counter to what you may have read, cornmeal is not for
use as a fungicide.
