Before & After Photos

I arrived at a home in Fords, NJ to inspect for possible rodent activity in the attic. The homeowner, who was hearing light “pitter-patter” noises in the wall voids and attic at night, suspected a mouse infestation. 

I’m often asked why attics such a popular location for mice to live and breed. Well, from their perspective, this “penthouse” location offers everything that a mouse could ask for in a home — it’s warm, dry, small, dark, safe, and out-of-the-way. Also, there is little human traffic up there. Other than using the attic to store clothing and other household items, a home’s occupants rarely venture up there, so mice have the place all too themselves. Attics also offer mice a ready supply of comfy insulation that they use for nests, and there are a virtually infinite number of nooks and crannies to explore and hide in. 

Once mice infest the attic, they not only destroy expensive insulation with their droppings and urine, but they can also chew on electrical wires, creating a potential fire hazard. Mice in the attic are a health hazard for the entire home. While mice may live in the attic, they are scavengers that venture throughout the entire home in search for food. And they inevitably find their way into the kitchen where they bore through cereal boxes and other cardboard containers, contaminating food and spreading disease. Mice are especially attracted to homes where pet food is left out all day. For a mouse, there is nothing better than a continuous supply of food left out in the open for the taking. 

While in the attic, I observed several areas with the most obvious sign of a mouse infestation: distinctive pellet-shaped mouse droppings. A single house mouse can deposit up to seventy-five pellets daily. Multiply that by a dozen or more mice and it doesn’t take long for these filthy droppings to accumulate. I also observed rodent burrows, those little tunnels and runways, in the insulation. Finally, during my inspection, I look for potential access points. In this attic, there were gaps and open voids around electrical lines and pipelines, giving them easy potential entry points.

I started my treatment by setting a tracking powder inside all rodent burrows, pathways and entry points. Mice may hide in the attic, but they have to leave in order to feed. Mice come into contact with the tracking powder because these creatures of habit use the same runways and entry points over and over. This potent powder, which adheres to a rodent’s fur and paws, is ingested when the rodent grooms, killing them soon thereafter. I also sealed and patched the rodent entry points with copper mesh. Finally, I set up rodent bait and snap traps in the attic. After finishing my interior service, I moved to the outside of the home, inspecting for possible entry points. I found a large potential rodent access point around the A/C unit lines going into the home. I sealed that opening and treated around the area. Finally, as an extra precaution, I set up some exterior rodent bait stations.

I explained my findings and treatment to the homeowner. He was pleased that he was well on his way toward having this troublesome mouse infestation permanently resolved. 

This Woodbridge, NJ homeowner had a mouse infestation in her basement. We set up a baiting system, and, fortunately, there was no indication that there was still an active infestation. However, mice and other rodents are messy home intruders, and they left behind a toxic mess of fecal pellets and urine stains. We completed a thorough clean-up of the basement, sanitizing and deodorizing the area. 

After completing the cleanup, we returned to remove unsightly stains left my the mice. Mice not only leave urine stains, but they also leave behind runway tracks (rub marks). Mice have poor eyesight, and they facilitate movement by hugging walls as the travel. The mice memorize these routes and rarely stray, enabling them to run rapidly along a path, even in the dark. Over time, they leave a faint, dark trail of body oil and dirt. 

We also replaced a rotted piece of fascia under the rear slider that was an entry point for the mice. For long-term rodent control, it is critical to exclude them by blocking all of the known entry points.

The homeowner could not have been more pleased. She was happy to have her basement back with no more “reminders” that there once was a rodent infestation down below.

A homeowner in Keasbey contacted Cowleys after hearing strange wildlife scratching and scurrying noises in her basement and inside her wall voids. Mice use wall voids to travel unseen inside a home when foraging for food. Even though mice inevitably find their way into the kitchen for food, they may be nesting anywhere. Rodents have a “gift” for staying out of sight since these nocturnal creatures do their foraging at night. Often, you’ll see signs of rodent activity well before spotting a live rodent, and it is important to keep your eyes, ears, and nose open. Mice populations increase rapidly, and you want to address these infestations as early as possible.

This homeowner was quite happy to see me when I arrived, and was thankful that I was sent out immediately to deal with the infestation. For a homeowner, those unfamiliar squeaks and scratches can be quite disturbing, and she wanted whatever trespassers were hiding in her home to be gone.

All indications were that this home has a mouse infestation. I inspected both the home’s interior and exterior for rodent activity. Although the mice themselves may be hard to spot, they are messy creatures that leave behind plenty of signs, including clusters of their tiny, dark pellet-like droppings, smelly urine, chewed wires, and clumps of insulation, paper, cardboard, or other nesting materials. Sometimes you’ll see mouse markings on walls, which are stains left from the dirt and oily residue in their hair.

Also, during a rodent inspection, I am always on the lookout for potential access points. Entry points need to be identified, so an exclusion can be performed. Exclusions prevent more animals from finding their way inside your home using the exact same routes. In this home, I found several gaps around pipes and other areas, as well as a small basement window that had been left open for some time giving the rodents an open invitation for entry.  

I closed the window and spoke with the homeowner about making sure that all ground-level windows stay shut. After setting a rodent tracking powder inside the gaps and voids, I sealed them with copper mesh. Copper mesh effectively blocks out mice. Mice can chew through wood and a lot of other material, but not this stuff. After treating burrows and patching the holes and gaps, I set up rodent bait stations around the exterior of the home and inside the basement in order to trap any mice still lurking in and around the home. 

We received a call from a homeowner in Freehold, NJ who was suffering from raccoons in her attic. After our wildlife team took care of the raccoons and blocked up their entryway we needed to take care of the damage they did in the attic. Her attic had been decimated by raccoons. There was an abundant amount of raccoon feces and urine all over her attic. Raccoon feces and urine are harborage areas for viruses, bacteria, and parasites. Most notoriously the parasite Bayliscacariscc procyonis — also known as "raccoon roundworm.”  Once it enters a human, serious symptoms can emerge within days. This parasite invades the lungs, liver, heart, eyes, and brain and sparks serious inflammation throughout the body. While some people make a full recovery, the infection can leave others blind, in a coma, or with permanent brain damage. It's sometimes fatal. 

First, we put on our personal protective equipment and removed all of the soiled fiberglass insulation that contained raccoon droppings and urine. Once raccoons made their business in your attic and on your insulation, you have to get rid of it. Afterward, we carefully removed all the contents and then sanitized and deodorized the attic. Not properly cleaning up your attic can lead to serious health risks. By using a broom or vacuum, you increase the risk of dangerous air particles raising, hence increasing the risk of contracting the roundworm parasite. Finally, we blew in cellulose insulation. Cellulose insulation is made from ground up recycled paper. It is treated with different types of applications that aren’t hazardous to humans and provides resistance to mold, pests, and fire.

This homeowner in Avenel, NJ contacted Cowleys for a crawl space improvement. Cowleys has an experienced crew that handles various crawl space improvements, up to and including full encapsulation and whole-house dehumidification for homeowners with water and moisture issues. These issues often result in mold growth that then affects the indoor air quality of the home.  

This particular installation job was more limited, and we are more than happy to adjust the scope of our work to meet the particular needs of the homeowner. The homeowner did not require full encapsulation (Cleanspacing”) because the crawl space was dry and did not have humidity levels that would be conducive to mold growth. However, the customer decided that it was time to replace his flimsy 6-mil “contractor bag” vapor barrier with something more durable and substantial in order to deal off the dirt and prevent dust and odors that periodically permeated the living areas above. 

To meet the needs of this homeowner we removed the old barrier and replaced it with our tear-resistant heavy-duty 20-mil CleanSpace vinyl vapor barrier. This vapor barrier is only available to licensed Basement Systems dealers. Our barrier is a specially engineered film made of layers of high density and low density polyethylene, and you  can walk on it without worrying about rips and tears. With its mil thickness, this barrier has the durability of a plastic tarp. 

The homeowner was quite pleased with our installation work and informed us that if he ever needed additional crawl space renovations, he’d have us back in an instant.
