I found an article from TAMU suggesting some controls.

Pam

Here is a link that might be useful: Leaffooted Bug controls

The Leaf Footed bug family is a fairly large group that includes the Squash Bug, Stink Bug, Box Elder Bug, and others. Some are predators of other, more destructive, insects while others are simply destructive in their own right, and some are fairly innocuous . Controls are similar to those used for Squash Bugs and Stink Bugs, when necesary. Floating row covers, hand picking, searching for egg masses and squishing those found, Insecticidal Soaps, Neem oil Sprays, and as a last resort pyrethrin dusts or sprays.
Since there are many predators of these pests using the broad spectrum sprays suggested in the link above will kill off any of those predators making the problem even greater.

Thanks Pam! I have been plagued by these critters for the last several years. I have put a row cover over the tomato's, hope this helps!(what respectable creature trys to eat citrus?)

p.s. sorry for listing this in the wrong place folks!

During the fall, the leaf-footed bugs and certain other insects, among them the Asian lady beetles, hang out on the sides of structures.

The time when they are garden pests is during the active growing season. But now -- fall and winter -- they are considered nuisance pests, only. In general, pesticides do little if anything because the insects aren't feeding nor are they breeding.

That said, insecticidal soap can knock them down. And a wet/dry shop vac, with some slightly soapy water in it, can suck them up so that they drawn.

Typically, these critters arrive at the same time each fall. So jot the date on a calender and NEXT year, schedule a pest control company to spray the side of the structure where they congregate a WEEK prior to the bugs' expected arrival.

The spray won't kill them but will repel them.

The reason they return yearly is that the previous year's crew put pheromones on the wall which, in effect, tell next year's bugs that "this is a good place to spend the winter."
