I need to wage some all out war on the ants that are getting into my strawberries! Any suggestions? Need something organic of course! Thanks!
I use a sugar based product called Terro, and it is very effective. I am not sure if it’s organic. We just put a dime-sized dollop on several pieces of cardboard near our baseboards and it works every time.
In the event that it’s not organic, you might try diatomaceous earth, which is. However, I haven’t read about its efficacy on ants.
You can always consult an entymologist with your state’s cooperative extension service. Here’s a link to the University of Minnesota’s extension brochure on ant control: http://www.extension.umn.edu/distribution/housingandclothing/dk1015.html
I just realized you were talking about ants on your strawberries, not in your house. To reframe — I think diatomaceous earth is a good place to start, if it’s effective on crops. It will not harm plants or pets or people.
Otherwise, contact the entymology dept. at your local cooperative extension service is the way to go. Also, a horticulturalist specializing in fruit crops at your extension service may give you expert advice.
We have used beneficial nematodes before for ant control. They don’t offer immediate relief, but you will see improvement within a week or two and they will ultimately eliminate the ant population in following seasons if used correctly. I would say that seeking advice at a local organic nursery is always a great option as well! Best of luck.
cucumber peels have worked best for me. Or powdered cinnamon and black pepper mix.
Nematodes have also helped me with grubs, fleas, ticks, and mosquitoes. Great beneficial insect! They do need to be reapplied once or twice a year to be completely effective but anything to keep the villains of nature under control is worth my dimes and nickles. I have never tried the cucumber peels but I always keep an open mind, sounds like a good idea. Cucumbers contain a compound known as “trans-2-nonenal” that repels ants as well as cockroaches. Thank you Kiskin for the hot tip!
