In other parts of the country, cockroaches move in and out and from house to house and apartment to apartment with such regularity that people who want to maintain their sanity have monthly visits from pest control operators to remedy the problem. And make no mistake--they are a problem, tracking around disease vectors, causing allergic reactions, eating each others' fecal matter, and just generally being disgusting.
We recommend an extremely thorough cleaning of the home first. I mean, pull-the-fridge-out-remove-the-oven-drawer-and-get-out-the-bleach-and-sponge-and-go-to-town type of cleaning. All hyphens aside, what we're trying to do here is eliminate food sources they can use. Even a tiny spot of jelly is equivalent to a cockroach banquet, so you have to start with a clean slate before the baits work well.
Then we come in, and use state-of-the-art baits and occasionally insecticidal dusts (boric acid, etc), growth regulators (to prevent more reproduction), and aerosols to give them a massive punch. Even then, we recommend two follow-up visits, because eggs will keep hatching and nymphs will keep emerging for several more weeks.
