Demon WP can be reapplied every 4 weeks. If you are still seeing Palmetto Bugs, then the best course of control is to find the source - Palmetto Tree? If that is the case treating the tree can help and also spraying under the canopy of fronds (where the like to hide). If this is not the case, then any organic source where they can hide such as under mulch, firewood, rocks, etc can be an problem. American cockroaches are also called Palmetto Bugs in some areas although they are different. But American roaches love sewers, drains, etc. They will actually crawl from a sewer system up the drains in your house and enter that way.
Bottom line is that simply spraying a little here and a little there sometimes won't work. If they problem persists its because they are living somewhere and you have to find the source and eliminate it.
