Pests We Treat Before & After Photos

Recently, I was sent to a home in Rumson, NJ to resolve a troublesome mouse infestation. The homeowner had observed mouse activity in the garage and utility room, and contacted Cowleys before they found their way inside the living areas of the home. Here, the back wall of the utility room directly abutted the garage. Garages are common entry points for mice and I inspected the area to determine how they could be gaining access inside. There was no shortage of entry points. The mice had numerous ways to get inside the garage. I showed the homeowner what needed to be done to stop the mice from gaining access. Both the garage door and side door had openings that needed to be fixed. Often, weather stripping can deteriorate leaving openings and garage doors do not close all the way down. If you can see daylight coming in, assume a mouse can as well. 

I went to work plugging the the hole in the wall into the utility room from the garage with a chew-proof copper mesh. I also installed three RTU (Ready-to-Use) bait stations. These stations have a special key needed to open up the boxes to apply the bait cannot be accessed by non-target animals. These stations also allow me to monitor the level of rodent activity when replenishing the bait. After finishing up with the garage, I plugged up the holes in the utility room and installed two more RTU bait stations there. The homeowner did the right thing by contacting Cowleys at the first sign of rodent trouble. It is far easier to deal with an infestation before they gain access in the kitchen and other living areas of the home.

We were sent out on a service call to a home in Rumson, NJ to treat for hornets. When we arrived, the homeowner mentioned that the nest was right above her backdoor. Sure enough, when we checked, we found an active bald-faced hornets! Bald-faced hornets are social stinging insects that are a close relative to yellow jackets. The surface of their upper midsection almost looks triangular from the side, and they have white markings on their face. One very important fact that you must know about bald-faced hornets is that they are EXTREMELY aggressive and will not hesitate to sting anything that invades their space. Their stings carry venom that makes the stings hurt, itch, and swell for about 24 hours!

First, we equipped our personal protective bee suit and treated the nest with a knockdown dusting application and then a knockdown liquid product. Both of these treatments will exterminate the bald-faced hornets almost immediately. Once a majority of the hornets were eliminated, we removed the nest, properly disposed of it, and then treated the area with a residual product to eliminate any returning bald-faced hornets & prevent them from building another nest. 

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. 

Recently, I went on a service call for a new residential client in Long Branch, NJ who contacted us to resolve an issue with birds nesting inside her home. Before beginning my inspection, I spoke to the homeowner about the bird infestation. Whenever possible, I always try to speak with homeowners about whatever rodent, pest or wildlife issue they are dealing with. This preliminary information helps me identify the problem, target my inspection, and find the best solution. Here, the homeowner told me that she saw a bird hovering around on the exhaust vents on the side of her home. Birds are attracted to exhaust and dryer vent ducts to nest because they are private places to lay their eggs hidden from potential predators and they like the warm air that flows through them. So, I already had a good idea of the problem.

As I inspected the exterior of the home to find the birds’ point of access, I came across a damaged plastic exhaust vent. Contractors debate plastic vs metal vent covers, and plastic has certainly become more popular in recent years, especially the new plastic resins like polypropylene. Unfortunately, there are also cheaper plastic vents installed that are prone to cracking and breaking down from exposure to the sun and the harsh outdoor elements. Over time, plastic exhaust vents can get beaten up pretty badly. Occasionally, when the fan turns on, the vent fins get stuck open, and that was the case here. As often happens, birds exploit the vent opening to build a nest inside the home. Damaged exhaust vents not only allow birds and other critters to gain access to your home but also allow moisture to come in, which can lead to mold and mildew problems. However, the biggest risk of all is the nesting material obstructing airflow and creating a fire hazard.

After carefully removed the nest, I sanitized and deodorized the vents with a solution that targets bird mites. Bird mites are parasites that feed on the blood of birds. When birds leave their nests, the mites are left behind without a suitable host for their next blood meal. They will make their way into a home, and once inside they will take over, climbing all over your walls, ceilings, and beddings. To make matters worse, bird mites are tiny and semi-transparent, so they are extremely difficult to detect.  Bird mites are the main reason why extreme care is needed when removing a nest. The last thing you want to do is disrupt the mites that are crawling in and around the nesting material. 

After removing all remnants of bird activity, I replaced the vent with a newer, upgraded exhaust vent with new fins. As added security, I placed a screen on the inside of the vent to prevent any more birds from attempting to access that area. Now, after completing this job, this home is bird-free with a new and improved exhaust vent. Best of all, there is a homeowner who is immensely relieved that her bird problem is gone!
