It eats the leaves. Squish the eggs and bugs whenever possible. Negative matt5797 On Jul 30, 2006, matt5797 from Gallatin, TN (Zone 6b) wrote: This bug is devastating if left on squash plants. At first, they may be noticed greedily feeding, with no visible plant problems--They look much like a stink bug and carry the odor also. The plant then starts to lose its older leaves, and younger leaves may wilt and turn yellow toward their edges. While the plant is still at least one half unharmed, you must hit them with Sevin or another harsh pesticide or your squash plant will likely die. Apply in dry conditions so the pesticide remains active for hours and make sure you get the whole plant. Pay attention to the undersides of the leaves. Organic sprays are usually no match for the hardy bug. Negative city_of_refuge On Jul 31, 2006, city_of_refuge from Chesapeake, VA wrote: I had some beautiful hollyhocks that were doing really well. I started noticing that the leaves were starting to turn brown and die. I don't know if the heat did them in (the seeds came from my father's hollyhocks in Vermont) and I never researched to see if they could stand the weather here in Virginia. I did find these bugs all over the leaves though, as well as their eggs. I killed as many as I could, bugs and eggs. Maybe I was too late. I saved a couple of the bugs--put them in a jar. I was going to try to find out what they were. Now I know, thanks to this site! I lost that patch of hollyhocks--I do have others growing though. Hopefully they'll bloom this year! Thanks for the informative site.

I rarely see them on my melons or cucumbers but I have read they will attack any cucurbit family plants. I have also read some companion plants will deter or repel these bugs but I am just now planting them so I have nothing to report on results yet. Two of the plants I am trying are nasturtium and tansy.

I went away for a short vacation and noticed when I returned that my cucumbers were over-run by Squash Bugs. What a mess! Luckily I got them away from most of the tomatoes and other plants. I yanked all my cuke plants and am trying to replant at this late date. We get veggies until the late fall so I may be able to recover some crop. Does anyone have a favorite bug killer I could use on these little beasts?

Wasn't sure what they were at first or if they were a good or bad bug, but after watching, noticed them sucking on the stems of new growth. Picked them both off & researched. The coreopsis did fine this summer with regular deadheading & I've not seen any more of these bugs, but will be on the lookout now & in the future.

Went on a trip for 10 days, came home to wilted zucs, buttercups, butternut...these armoured $ob's were even sucking on the "fruit", causeing funky shaped cuc's and skabby patches on the winter squash. I got down to thier level and noticed it was a baby boom!! Nymphs & eggs everywere! I'm going to try to "heat sanitize" the soil this fall and again next spring...it's got to help...it can't get much worse!!

Put some boards all around the plants. For some reason the squash bugs like to live under them. This way it is easy to catch them. ~~~Jeff~~~" Negative stephaniadawn On Jan 9, 2007, stephaniadawn from Agra, OK wrote: once it finishes with your squash and runs out of that it will move on to other plants. it devistated most of my garden one year. only thing that i have found will get rid of them is picking oand squashing and spray with polya from gardens alive. they lay there eggs on underside of leaves. i remove leave an burn. also spray all heavly with poyla. Negative Raine_Bradford On Mar 2, 2007, Raine_Bradford from Paonia, CO wrote: Once squash bugs find your garden, they are going to be there permanently, as they winter over in protected areas nearby. That's the bad news. The good news is that they can be controlled to the extent that they don't ruin your cucurbits. The best way to control these nasty predators is to start before you see them. Use sevin dust on your plants once the plants are just a few inches tall. Weekly applications will insure survival of your plants. If you are worried about staying organic, rotenone will also work, but it doesn't kill the adults. So you have to really stay on top of the spraying. Unless you have a very small garden or lots of time on your hands, forget hand picking the bugs.

I was unaware that they would attack tomatoes....... This year I am thinking of planting a sacrifice crop.

One day the plants were gloriously healthy with many flowers and fruits, the next the leaves looked wilted, and within a week everything was brown and crunchy. Negative dovey On Sep 5, 2008, dovey from Columbus, OH (Zone 5b) wrote: These things are devastating, we had several healthy squash plants and one huge pumpkin plant. In a matter of days the plants were over run with squash bugs. We trimmed off leaves with eggs on the backside and sprayed with neem... 10 out of 12 squash plants have died. I'm ready to dig up the last 2 just to be rid of the bugs. After some research this is what I found regarding organic control. Organic Control: There are few if any effective organic control options for squash bug. However, natural enemies of the squash bug include Tachinid fly, Trishopoda pennipes and Sceleonids, Eumicrosoma spp. These biological control options may prove useful. Sabadilla may provide some control and is organic certified. Apparently Neem Oil is not the answer. Negative jadira On Sep 6, 2008, jadira from Mantua, OH (Zone 5b) wrote: I found this bug this summer on my first ever crop of pumpkins. Nasty. They have turned leaves brown and even munched on the fruit itself, although this could also be slug damage. (According to Dept of Entomology at U. of Minnesota, anasa tristis will even eat the fruit. [HYPERLINK@www.vegedge.umn.edu]) See my photos! I haven't yet decided how I will manage them other than with boards and cleaning up debris. I hesitate to spray since this will also kill pollinators.
