Our backyard became a mass of tunnels last year (moles I suspect) and we would like to take action early this year to eliminate the grubs we suspect they are feeding on. We hear that nematodes are a good solution but had a couple questions.

First, does anyone have experience with them?

Second, how warm does it need to be before we release them?

Third, we have located a website that seems reputable and with decent prices (growquest.com). Has anyone dealt with these folks or is there another recommended source?

Thanks

See if this will help.

Grub Control

I have worked with nematodes for years. First of all were are you in the US? This makes a difference in what nematode species you get. Not all nematodes species are the same. Whom ever you buy them from should be able to tell you what species your getting. Dont let them tell you its a secret... that means they may not know.

I always get my nematodes directly from the nematode producer (never from reseller)

I did a trail a few years back comparing products and i found that the product from www.nematodary.com was the best. That is who I always buy from.

One thing though you missed your application window for optimal grub control. Insecticide or nematodes should be applied in the fall, usually around Sept. You can catch another small window in the spring but you need to make sure grubs are near soil surface and not down in the soil pupating. Again this will vary with your location.

Here is a web page from my website that might help you out.
