Remember these from when I was a kid, never messed with me and I even handled a few, I remember others kids would try to squish them and I felt bad so I'd put them in trees (but again, I NEVER put the bugs near my eye since I was always scared of something going in my eye).

Only seen one once in the backyard but I hope they return, they're so cool-looking. I fear that since everyone uses pesticides but me that they might be extirpated from my neighborhood.
Wish I could take the ones people keep trying to eliminate :P

this has been a particularly bad late summer for these walking sticks. it seems like they are always hanging out eye-level on the house so i spray and kill every one i see. i use liquid castile soap and water and soak each one from a spray bottle. it kills them within a minute.
if they didn't have the potential to cause such eye harm to me and my dogs, i would certainly leave them alone but having five or six every night around the house outside is just too much to deal with.

Wehave a smaller similar species in our area-
they smell bad but are not as dangerous to
pester as yours are- in a jar they die if they spray
so they are not immune to t he stuff!

Oh my, I didn't know that they shoot out a chemical that can do that. It seems that they are very accurate. I found 4 or 5 of them (like a family) different sizes. They freaked me out and I killed them. I didn't know what they do at the time and I usually don't have that reaction to insects or "bugs" but that one set off all of my internal alarms. Happy I listened to them. Diana in Louisiana.

I had a neighbor's dog sprayed by one in the eye and it suffered terribly. As it was on the weekend, the emergency vet bill was something else too. I had been unaware of this aspect of this insect until this event and now it seems we have them growing in some adjacent oleanders, rose and palm plants on our driveway. I will eliminate everyone I come across as I have two small and curious dogs to protect. I thought they were perfectly safe until this happened
and really didn't believe it to be true when I first heard it. Oh, well.

Location: Lafayette, LA. July 2009.

Although I've seen these bugs before over several years, it's been very long in between sightings and is rare that we encounter them. I saw a mating pair, at night, on my front porch on July 2nd. I left them alone. I have oleanders and monkey grass, so there is lots of ground cover to hide in near the front porch. On the 4th of July, our Maltese stuck his face near what we believe was a Two-Striped Walkingsitck on the back patio. It was dark and the event was captured on security camera, but you can't see exactly what the insect was, only the dog's reaction. We did see a large 3 to 4 inch long slim dark object scurry away under the fence board when it actually happened. We reviewed the security tape in hopes we'd see more.

(Note, my "negative" is about the BUG!)

I had one of these shoot that stuff at me. I was bending down working in the yard and didn't see there were tons of them on the leaves of a palmetto scrub. All hooked up together, if you get my drift. Tons of them.

Next thing I knew, I had a horrible taste in my mouth. I'd been breathing hard and my mouth had been open and the stuff went right in! I must have had my face down near them and didn't realize it until too late.

Needless to say, I started spitting as fast as I could and was very careful not to swallow the horrible tasting whatever-it-is. I ran to the kitchen and flushed my mouth out with water for a good 10 minutes; the taste was that awful and took that long to get rid of.

For those who have small children, or fear no bugs please read this!! These walking sticks will shoot a white substance from their bodies for defense. They can aim up to 1 ft with accuracy.
****Medical Importance***
The first account of its effect on humans that could be located was by Stewart (1937), who wrote about an incident in Texas: "The victim was observing a pair of Anisomorpha buprestoides . . . with his face within two feet of the insects, when he received the discharge in his left eye. . . The pain in his left eye was immediately excruciating; being reported to be as severe as if it had been caused by molten lead. Quick, thorough drenching with cool water allayed the burning agony to a dull aching pain. The pain eased considerably within the course of a few hours... read more
