Pests We Treat Before & After Photos

Recently, I was sent to treat and remove a paper wasp nest for a homeowner in Oakhurst, NJ.  

Paper wasps have that typical appearance we associate with wasps — a slender waist and long legs. They are called “paper” wasps because of how they build their nests. These wasps gather fibers from plant material and mix it with their saliva to make a brown or grey papery material for nest-building. They will build a small paper nest with a single tier of open cells to lay their eggs and rear their young. The nest has no external covering and looks like an umbrella, (that’s why paper wasps are sometimes called umbrella wasps). These nests are commonly attached to the underside of some structure by a short stalk.  

Paper wasps, like any social insect, live in large colonies with a queen and the supporting workers that keep the colony thriving. Other social wasps that we regularly receive calls for are hornets, and yellow jackets. Although paper wasps are considered less aggressive than these other wasps that’s of little consolidation to anyone stung by one of these guys! Any wasp will aggressively defend its nest if it perceives someone as a threat, so a wasp nest that’s in an area where people are regularly walking to and from is a potential hazard that must be removed. If a nest is located somewhere on the property where it’s out of the way and not likely to be disturbed, I recommend to just leave it alone. Wasps can be beneficial insects by reducing other insect populations on the property.

For this nest, I used a quick knock-down aerosol and then removed the nest. These stinging insect jobs are particularly rewarding to me because I know that I likely prevented some awfully painful stings. 

A property manager of an office building in Oceanport, NJ spotted an active hornet's nest along the roofline of his building and was terrified that his workers could get stung, so he called our office for help and I was sent out.

Once I found the nest, I took a closer look and several angry bald-faced hornets came flying out. Bald-faced hornets are social stinging insects with white markings on their face and are a close relative to yellowjackets  — which means that they are extremely aggressive. Their stings are extremely painful and, because their stinger isn't barbed, they can sting multiple times.

I grabbed my extendable pole, attached an aerosol knock-down application to it, and began treating the nest. This product will exterminate the bald-faced hornets almost immediately. A short while later, I removed the nest, disposed of it, and applied a residual along the entire roofline of the office building to prevent future stinging insects from infesting the area. 

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.
