In most cases, termite services take about an hour to complete. Here is the breakdown: - A standard Sentricon installation can be completed in 45 min to an hour. Special conditions may require more time. - An annual bait check and reinspection will usually take about an hour, depending on the number of stations to inspect. The best way to figure this out is to expect 1 min per station at a minimum, plus 30 minutes for the reinspection of the outside and crawl spaces of the home.
