Mice Infestation in Holmdel, NJ Home

I was sent to Holmdel, NJ to help homeowners who were dealing with a mouse infestation in the void above their basement ceiling. After finishing up exercising on their basement treadmill,  the homeowners heard some strange noises above their heads — the scratching and scurrying noises of mice above their heads. Mice prefer to stay away from well-lit areas and stay in out-of-the way places like wall voids and above ceilings where they can come and go and move around the house as they please. When things are quiet, these sounds tend to amplify, and often, homeowners think that they are dealing with a much larger problem like squirrels or even raccoons. Of course, no homeowner should ever think that it’s “just mice.” Mice and their urine and droppings can contaminate food and counter tops. Like any wildlife, they are a health risk to a home’s occupants.

Needless to say, the homeowners were right. Mice had entered their living space from outside. Mice usually enter homes around gaps and cracks in the foundation, and I began my inspection in the basement, first popping out some tiles near where they had heard the unwanted visitors so I could get a better look. There were some mice droppings on to of the ceiling tile. I immediately saw how the rodents were gaining access. There was some daylight coming from a small opening on the outside wall. There was a hole drilled through the foundation, possibly for a exterior water spigot. However, nothing was ever installed and the hole was never sealed. Mice exploited the opening and came into the home.  Mice only need a hole about the size of a dime to squeeze through. These rodents are even smaller than they look because of all their fur. They have no collarbone, so if they can stick their head through an opening, the body will follow.

I always carry disinfectant and a hepa vacuum with me. I first sprayed the the droppings before cleaning them up. It is dangerous to disturb dry droppings because microscopic particles containing dangerous pathogens like potentially fatal hantavirus are released into the air.   

Preventing entry is key to rodent control. I stuffed the entry points with copper mesh that rodents are unable to chew through. Finally, I secured a rodent bait box on the home’s exterior near the hole. The combination of these strategies will soon put an end to the mouse problem for these homeowners.
