I know that Palmetto bugs HATE eucalyptus. If you can find a tree, take a few small branches and put them behind your furniture. It smells nice, and the roaches HATE it. This is what I've been doing for over 19 years here in Florida, and it works. Change the branches once a month or so
You could also get some eucalyptus essential oil and apply that to the baseboards with a q-tip once a month.
