I've had the biggest problems with Asian Stink Bugs (an invasive species that is terrorizing the Midatlantic USA region) and Asparagus Beetles. Oddly enough the asparagus beetles (right pic) are mostly found on my radishes, turnips and brassica, and only occasionally on my (young) asparagus. The stink bugs (left pic) are the worst, since the birds won't even eat them.

I've been hand picking and squishing them all, and I've occasionally used neem. But I'd prefer to scare them away or confuse them with some flowers or herbs so fewer of them will show up in the first place. Any suggestions?

Basil, Calendula, Nasturtium, Parsley, Petunia, Tansy, Tomato, and marigolds are all good at preventing bugs and especially the asparagus beetle. Companion planting of flowers and herbs with your veggies will make a big difference! Good luck!

  • Calendula and Tansy; hadn't heard of those. Thanks. Unfortunately, the Asian Stink Bugs love some of my tomatoes, although they leave others alone. I wonder why... Jun 10, 2011 at 16:26
  • Stinkbugs eat ripe tomatoes.

Marigolds are the standard repellent for both of these insects. I plant marigolds all over my garden, particularly around my tomatoes and asparagus. You can also try catnip or mint, although you need to be careful because mint has a pretty aggressive root system and can take over anything you plant it in. I put mint in a medium sized pot near my raised beds so I can contain it.

A good resource for learning about companion planting is this website: http://www.companionplanting.net/

  • Marigolds are great. I've got a dozen interspersed through my garden, but I guess I should use them even more aggressively than I already have. :) Jun 10, 2011 at 16:32

    Marigolds are supposed to repel rabbits too. However, I had japanese beetles living inside my marigold blossoms last year. Jun 10, 2011 at 16:49

I have had the asparagus beetle problem this summer. I bought some petunias and planted them all through the bed. I also sprinkled marigold seeds throughout. I then let a big bag of ladybugs loose on the bed. They seemed to get the majority of them under control. But, here is a homemade tonic the bugs really hate. I got it on this link.

I still have to check the plants each day and do some squishing, but it is getting less and less.
