Before & After Photos

Here are some “before and after” exclusion pictures that I had taken as part of a job to resolve a mouse infestation for a homeowner in East Brunswick, NJ. When dealing with rodents, it is critical to determine how they are gaining access inside the home. You can go ahead and set up bait traps and apply applications to deal with the mice inside the home, but to permanently resolve the problem and prevent re-infestations, you need to locate the entry points used by the mice to gain access into the home. Sometimes you know they are actual entry points because of nearby rodent activity near the gap or crack. For example, if you find tiny, dark pellet-like droppings or smelly urine near the gap or crack, you are pretty much guaranteed that some mice availed themselves of the opening to gain access into the home. Other times during the inspection, the technician may find potential entry points that need to be sealed. 

Finding the gaps and cracks can sometimes be a challenge. Mice are tiny creatures and they can fit through a hole the size of a dime. A good inspection requires a thorough visual of the home’s entire foundation. Often, mice enter into the crawl space or attic and then use wall voids to maneuver their way around the home, eventually making their way to the kitchen to forager for food. Sometimes, the gaps are small and it takes a lot of detective work to find them. However, there are occasions where you’ll find a huge gap that for a mouse would be the equivalent of the Holland tunnel! That was the case here. With this home, there was a huge gap around a utility pipe entering the home. The gaps around pipes and wiring entering the home are always treated as one of the “usual suspects” to check when looking for rodent entry points. Here, you can see the large gap around the pipe.

To seal this gap, I filled it with chew-proof copper mesh. Rodents are persistent creatures that can tear and chew there way through many materials. For example, using caulk to close gaps is never enough. With the copper mesh firmly in place, this access point for mice has been permanently blocked.

This homeowner in East Brunswick, NJ had a bat infestation a while back. Our wildlife team had taken care of the issue and he had a bat warranty with us should there be a later re-infestation. This year, he decided it was time for a new roof. Given his bat issues in the past, he wanted us to come out to the home to make sure that there were no new entries into the home before replacing the roof. We were happy to help out. 

During my roof inspection, based on the earlier infestation and how the bats had gained attic access, I recommended that he consider installing Ridge-Guards over the ridge vents. Ridge vents are an important, necessary part of a home’s roofing system. These vents allow damp, warm air to escape from the attic, which increases the home’s energy efficiency and helps protect asphalt shingles from overheating and warping in the summer. Unfortunately, these vents come with a downside. They are often exploited by small wildlife, especially flying squirrels, bats, and sometimes mice, to gain attic entry.  

This homeowner did not even want to think about another bat infestation after what he had gone through. I recommended that he consider Cowleys for installing a Ridge-Guard system. A Ridge-Guard is a breathable protective cover that we install over the ridge vents. This covering guards against animal entry through the ridge vents. We’ve used this product for homeowners looking for an effective way to prevent bats and other wildlife from gaining access through the ridge vent instead of having to deal with the messy, and often expensive to fix, aftermath of a wildlife infestation.  

As a wildlife technician, I must admit that I enjoy the challenge of capturing and outsmarting wildlife. However, for homeowners, preventing potential wildlife issues from happening in the first place is a far better alternative to dealing with an actual infestation. Cowleys has a separate contractor division with an experienced construction crew that handles various homeowner services including repairs caused by wildlife. 

I was recently sent out to a senior citizen development in Monroe Township, NJ to resolve a mouse infestation. The homeowner, who had quite a sense of humor considering there were rodents in her dwelling, told me that she was seeing “Mickey and friends,” but she was stumped as to how these little critters were gaining access to her home.

Usually, when inspecting for rodents, you’ll only see signs of rodent activity and not the pests themselves. Here, i found one of the most common signs of rodent activity — their droppings that they leave behind. Here, I found mouse droppings Considering near one of the poles in the closet. This pole happened to extend all the way up from the crawl space, and there was enough of a gap around the pole for mice to squeeze through to reach her closet. 

I applied a tracking powder along the pole and also excluded the space around the pole to seal off access. For rodent infestations, it is also important to conduct a thorough inspection of the home’s perimeter. During my outdoor inspection, I noticed a large opening underneath the exhaust. I took a picture of the potential rodent entry point to show the homeowner, and then proceeded to seal up that hole as well. 

After returning for a follow-up visit two weeks later, I was greeted by one happy homeowner. She told me exactly what i love to hear. She said that there were no further mouse sightings, mouse droppings, or any other signs of mice activity since my first visit.

A resident in Monroe Township, NJ contacted our office after finding squirrels in his attic. Squirrels can be very dangerous and destructive when in a home. Not only do they carry disease, but they like to burrow and make a mess of areas they can get into. Squirrels are rodents that need to chew, and they like the texture of wires or electric wires in the attic, which can present a fire hazard for the homeowner.

We began inspecting the exterior and discovered that the squirrels had chewed their way through this gable vent, which was their main access point to the attic. We then inspected the attic thoroughly and found squirrel feces in the insulation. To safely remove the squirrels, we temporarily sealed off the gable vent and installed a one-way device. A one-way device allows the squirrels to safely leave the attic, but prevent them from getting back in. We also set up a few baited traps in the area.

In a short amount of time, all the squirrels were safely removed from the attic. We then returned, removed and replaced the contaminated insulation, sanitized the attic area, and then replaced the gable vent with a brand new metal one. We also used fine 1/8 hardware cloth and screened it from the outside. The reason why we screen from outside is that it doesn't allow anything to roost or nest in the vent fins.

I was recently sent to a home in Edison, NJ for a Cowleys home protection plan (HPP) scheduled service. The homeowner had issues with rodents around the home and I found out why she was concerned.

In my inspection, I found an exterior rodent bait station by the shed that was completely depleted from the last service. The interior rodent bait stations in the garage and crawl space were also empty.

After completing the service around the home I rebaited all the existing bait stations. I then performed a thorough inspection around the house to determine how the rodents were entering the structure. I found a sizable gap around the piping where the gas line was passing through the foundation. To close up this access point, I used a copper mesh material which does not rust or disintegrate like steel wool. 

Since this customer's rodent pressure was so high. I added an additional large rodent bait station (LP) to the exterior of the home.
