The proper way to solve a rat or mouse problem is to fully investigate the house or apartment and find out how the rats/mice are getting in. Identify all of the points of entry, and then seal them shut – permanently. Then trap and REMOVE all of the rats and mice with traps, and the problem is solved for good, without any of the problem of stinking rodent carcasses.
General inspection from exterior to the interior is first. Discovery and closing the entry points are the most important in providing effective rodent control. We look for areas around the windows, garage doors, utility lines, dryer vents, door thresholds, downspouts and the most common area, the construction gap. This is an area at the roof line left open for ventilation purposes and is the most common area of entry for rodents and squirrels. Other factors to consider are areas that provide water, food and harborage for the pests. Examples of these areas around the home that may provide this are overgrown vegetation, wood piles, wildlife feeders, creeks, streams, storage areas, crawl spaces, dog or cat feeding sites, attics, garages and other areas that may be found during inspection.
