Before & After Photos

One of my biweekly commercial accounts, a restaurant in Keyport, was having ongoing issues with mice, despite our best efforts in locating and sealing possible entry points. According to the day manager, mice were running back and forth between a two-door area (see photo). So, I began my inspection by carefully looking for entry points in this area. Each door frame had a slight opening behind the baseboards. Mice had created their own point of access by chewing themselves a pathway to get around the bar area of the restaurant (see photo). 

I patched each hole with copper mesh. Now, with the mesh blocking them, the mice had lost their route to get back into these areas. I then placed several “tin cat” glue boards around the utility closet adjacent to the entry point. The utility closet was the perfect harborage area for mice — it was small, dark, and easily accessible. 

During my next follow-up, I made significant progress with the infestation. My “tin cats” had snared several mice now that these entry points were plugged. I’m confident that as long as I stay on top of closing possible entry points into the restaurant, their rodent problem will be eliminated. 

The most important line of defense for mice is keeping them out of the structure in the first place, and the only way to do that is by being vigilant about inspecting the building’s exterior perimeter, finding entry points and sealing them. Also, inspecting for mice is an ongoing process. Just like what happened here, new entry points can pop up between visits. Mice are persistent, focused creatures. If they are determined to find their way inside a structure, they will keep plugging away, either by finding a new entry point or by making their own. Mice are able to gnaw and chew their way through wood and other building materials.

Homeowners in Old Bridge, NJ, recently converted their front porch to a year-round living space. There is a small crawl space underneath the newly converted area. As they started to use the area, they soon noticed a musty, earthy odor wafting up from the crawl space. Also, the floor was quite cold. They contacted Cowleys for some crawl space renovation that would buffer the cold air and remove the odors, and one of our crawl space encapsulation teams was sent over. 

To stop the cold air, we installed Silverglo insulation on the exterior walls. SliverGlo is a lightweight, rigid, and closed-cell insulation that is much more efficient than over-the-counter batt and foam insulations that just isn’t designed for crawl spaces. Its closed-cell structure provides minimal water absorption and low vapor permanence. Other types of insulation act like a sponge in damp crawl spaces and, once wet, loses its ability to effectively insulate. We then installed a CleanSpace liner (vapor barrier) to encapsulate the area.This heavy-duty 20-mil liner is much thicker and sturdier than the generic “contractor bag” liners. 

With the crawl space sealed from the outdoor elements, the homeowners will no longer have a “freezer box” underneath their flooring and the odors will be gone as well. Considering that there were odor problems during the winter month, once summer rolled around, the problem would have gotten even worse. With the encapsulation, there will be far less likelihood of mold formation and the crawl space will stay nice and dry — the homeowners can now even use this “dead” crawl space area for storage if needed.

As I was performing a routine service for a Home Protection Plan customer in Keyport, NJ I noticed a viable entry point in the foundation of a house. Believe it or not, this opening is the perfect size for not just pests, but mice to enter the home. In fact mice can squeeze through an opening the size of a dime!

First, I stuff the opening with copper mesh. Copper mesh is an excellent way to exclude rodents from crawling into tights spaces because they are unable to chew through it. Next, I used black caulk to seal the opening. Afterwards I finished treating the home for their regular service. 

April showers bring May flowers, including heavy rains into crawl spaces! Recently, we received a call from a homeowner in Farmingdale, NJ who had an issue with their crawl space. During heavy rainfall, their crawl space kept getting flooded and the sump pump wasn’t working properly. Not having a clean crawl space can have a major impact on your family’s health in so many ways. In fact, 40% of the air in your home comes up through the crawl space. This means that moisture, mold, dust, and pathogens can seep into your home, where you're breathing it in. Asthma or allergy symptoms could be a response to this. Once we arrived at the property, we put on our Personal Protective Equipment (PPE), full-face respirator masks and began our inspection. After thoroughly inspecting the crawl space, we discussed with the homeowners what they needed. A crawl space encapsulation. 

Crawl space encapsulation eliminates moisture, prevents damage from moisture, keeps unwanted critters out, and saves you money on your utility bill. First, we removed all the debris out of the crawl space. Then we laid down drainage matting which will allow any water to work its way over to the sump pump. Once that was done we dug a hole to remove the old sump pump and installed the new sump pump. Then we filled the outside of the hole with stones to allow water to make its way into the sump pump. Finally, we lined the entire crawl space with a vapor barrier liner. The vapor barrier is a 20-mil 7-ply sandwich of high and low-density polyethylene with a polyester-cord reinforcement. It's also treated with an antimicrobial finish that protects against mold and mildew growth. This vapor barrier is made-to-take-a-beating and is puncture and tear-resistant. Now the homeowner will no longer worry about their crawl space getting flooded.

A homeowner in Hazlet contacted Cowleys after finding a mouse infestation in his basement. Once temperatures drop, mice and other overwintering pests try to make their way into our homes to shelter themselves from the harsh winter elements. 

Mice are nocturnal creatures that do their foraging in the dead of night, so they tend to stay out of sight. More often than not, you’ll notice signs of mice activity well before actually seeing one of these scampering pests. If you do see a mouse during the day, it may be a sign of a heavy infestation. The most common sign that you have a mouse problem is their small and dark droppings that they leave behind, often inside cupboard tops or along skirting. While mice and the size of their droppings are small, the quantity of droppings is a whole different story — a single mouse can produce upwards of 70 droppings a day! Mice also leave behind hairs, rub marks along regularly traveled routes, and track footprints in dusty places. Besides their droppings, other signs are smells (the ammonia-like smell of urine and the stench of a dead rotting mouse carcass are particularly pungent), and scratching noises, which often heard at night when they are moving about.  In addition, you may find easy-to-shred nesting materials and track footprints in dusty places.

Whenever I am dispatched to resolve a mouse infestation, after talking to the homeowner to get an idea of where the creatures are nesting and harboring, I first perform a thorough inspection. During the inspection, I meticulously do an inch-by-inch inspection of the interior and exterior perimeter of the home in order to find possible access points. Mice entry points can be easily overlooked and are a challenge to locate — they only need an opening about the size of a dime to squeeze their way inside. My inspection includes checking all of the utility lines and pipes entering the home to ensure sealed tight and that their are no gaps. With this particular job, even after re-tracking my steps at least three times, I could not find a single possible entry point around the foundation. From my early pest control days, I knew that a common access point was the garage door area. I checked the garage and the weather strips and garage door jams were perfectly intact. Finally, I checked around the home’s siding. And bingo - I found a very obvious entry point that would lead the mice into the garage, and from the garage into the basement. 

I sealed the gap in the siding. In the basement’s interior, I placed RTU bait stations that automatically lock once a rodent enters, and placed LP (low profile) bait stations around the exterior of home along with a dozen snap traps. I was confident that this internal-external trapping arrangement would capture most of the mice, if they were still around. After a three day follow-up, I returned to the home. No mouse activity was found other than a deer mouse caught in a snap trap. 

Two weeks later, I followed up once again, and still there was no activity. At this point, there was no longer an active infestation and mice were not gaining access into the home. I told the homeowner to always be on the lookout for mice activity, and if there was a problem, we’d be back to handle it. Mice infestations are not a one visit and your done problem. You often need to set additional traps and re-inspect, so it may take a few visits by the pest control tech to make sure that these pests are out of your home for good.
