Yellow stick traps placed in between the plants will catch them (but may

I use these traps every year and they seem to do the job just fine.

Just cut a sheet of yellow poster board into strips, fasten them in your
garden somehow about 12" off the ground and smear with a bit of Tree
Tanglefoot or similar product.

Weak plants have a yellow tinge to the leaves that the whiteflys can see.
Normally this means an easy meal for them. Unless, of course, the "leaf" is
actually a strip of paper with goo smeared on it.

Vaseline on yellow card stock will work too.
