Mice find easy entry into Long Branch, NJ home

Recently, I was dispatched to a home in Long Branch, NJ that was plagued by mice. Vermin were running around the basement and first floor of the home as if they owned the place. And based on the level of infestation, I have to admit, they temporarily had the upper hand!  But now that I was here, it’s game over for these rodents. 

Mice are overwintering pests that make their way into homes as outdoor temperatures drop. They can potentially contaminate food and leave droppings wherever they go. Mouse and other rodent infestations pose a serious risk for transmitting Hantavirus Pulmonary Syndrome (HPS) and other serious diseases. HPS is an infectious disease that starts with flu-like symptoms and can progress to life-threatening respiratory problems. Any activity that puts you in contact with rodent droppings, urine, saliva, or nesting materials can place you at risk for infection. Also, when mouse droppings dry and are disturbed, particles can become airborne and you can actually breathe them in. That’s why you never want to go into a small enclosed area where there is a rodent infestation without proper personal protective equipment like HEPA masks.

Mice tend to enter homes through access points in and around the foundation to get inside the basement or crawl space. Once there, they use wall voids to speed throughout the house, usually finding their way to the kitchen because of all the food attractants. Since mice are so small, there are often many entry points we are unaware of. They only need an opening about the size of a dime to make their way in. As such, they can easily squeeze their way inside through gaps and cracks in the foundation. Also, I’ve seen many homes where the mice have run along the sill plate until they find gaps around piping entering the home, such as a gas pipe behind the stove or water lines under the kitchen sink. 

During a rodent inspection, I generally start with the kitchen since this is their usual target destination. I then work backward to see how they are gaining access to the kitchen. With this home, after inspecting the kitchen for evidence of mouse activity, I moved to the basement where the homeowners had noticed most of the rodent activity. I inspected the entire home and even found mouse droppings in the attic, indicating to that mice had made their way throughout every floor of the home. 

While baiting for mice in the different areas of the home, I noticed daylight by the sill plate in the basement right by some wires. If daylight can shine in, it’s a good indication that there is enough of an opening for mice. A mouse can enter a home through a hole as small as the diameter of a dime. Since mice don’t have collarbones, if a mouse is able to poke its little snout through a hole, the rest of its body will follow. Upon further inspection, I found a large hole in the foundation — a hole large enough for a rat to enter let alone a tiny mouse. Someone had stuffed the hole with a rag. With the teeth and claws of a rodent, a rag would do absolutely nothing to deter a determined mouse or rat from getting into the house. I stuffed the access hole with chew-proof copper mesh to block any more rodents from entering. With the bait stations set up throughout the home, it will not take long for the rodent population to substantially decline. The objective, of course, is to get the rodent population down to zero. One mouse roaming around a home is one mouse too many!

I scheduled a two-week follow up to reinspect, replace the bait in the stations as needed, and determine if additional bait stations are necessary. With a heavy mouse infestation, it is important to have successive follow-up visits until there is no more observable rodent activity.
