How to inspect a house for house mouse entry holes.

House mice can enter a home or building in many ways. One main area to check for is your pipes. Often there are gaps that we don’t see at first but can later cause issues by providing unwanted entryways for our little rodent friends to enter. Another area is ground level venting around the base of your home. Such areas allow easy access into your home. The third way is by roof corner intersections.

Mice will enter a structure in any way that they can.
Generally, a hole will be chewed through a wall and this will allow access into your home. This will allow wires or pipes to break through and give mice access to your utilities, which will allow open entry into your home. You will never solve the rodent problem in your home, office or building unless you learn of their way of entry.

The house mouse and other similar-sized mammals only need the size of a quarter or a gap that is about 3/4th of an inch to 5/8th of an inch to enter your home. Always be sure to check vents, such as gable, roof, ground-level, crawl space and laundry vents. Check all doors, windows, and every area of your roof, including your fascia where the eave meets the roof. Check all roof lines (if you have a tiled roof), every plumbing stack, air conditioner chase and all power line entry points. Essentially, checking every square inch of your dwelling or work place for rodent entries is your goal in order to put an end to the vermin infestation.

Perhaps you aren’t experienced with ladders or heights; it can be a very frightening experience, but it quite possibly will be necessary to use a ladder to check all the critical entry points that I have mentioned. You must be very careful, however, to be cautious and wear a safety harness, as well as have someone else with you as a “spotter”. If the need should arise to check your attic, under your home, building, etc., wear protective clothing and gloves as a measure to avoid any possible injury or irritation to your skin.

Many rodents are infected with diseases, causing humans severe health problems.
When determining how these havoc-causing beings are invading, overlooking an entry can cause a more serious issue. Inspect the entire structure, literally from the “ground up”. Know the signs to look for, such as brown staining, grease at entry points, gnawing marks, an attic with rodent trails, etc. Being aware of such indications will provide you with an idea of how to repair these areas as well as areas such as gnawed piping and wires.

Clean areas soiled with rodent urine and feces are a good indicator. Soiled areas allow vermin continued entrance. Repairing damages and extermination is quite costly; therefore, you must get rid of the problem as quickly as possible to avoid more damage. Storing all foods in air tight containers will provide a lesser risk of disease transmission as well.
