Pests We Treat Before & After Photos

As temperatures drop, mice will seek refuge in your home to escape the harsh winter elements. For a mouse, your home is paradise — it’s always warm and cozy, there are plenty of nooks and crannies to hide, there’s plenty of nesting materials,  and your kitchen offers an unlimited food supply. , 

Whenever we are called out to resolve a rodent infestation, we not only treat the infestation. It is critical to determine how these disease-carrying animals are accessing your home. Here, in this home in Keansburg, I determined that mice were gaining access through gaps around AC lines entering the home. Utility and telephone lines entering your home to are common access points for small rodents like mice and they are always on the top of my “must inspect” list. A small gap around wiring or pipes that we easily overlook is, for a mouse, a wide-open entrance way that offers 24/7 access  into your home. Unfortunately, because of their diminutive size, mice can slip through the smallest of gaps and cracks, and these openings can sometimes be a challenge to find. I set up traps in the home and sealed the entry point to prevent further access. These pictures show the “before and after”  sealing of this entry point.

I’ll be returning for a follow-up visit in two weeks to make sure that these overwintering mice are gone for good. 

Summer is not only a busy time for us, but for insects as well. This is time of year when many insects are most active. They are at their population peaks and working hard to expand their colonies. Hornets in particular rear their heads (and stingers!) in the summer. During the summer, we see hornets busily doing their construction work. They build their nests not only in trees, but often on man-made structures as well. We will find their perfect hexagonal chambers attached to soffits, inside garages, attics, on window sills and door frames, attached to exterior walls, and pretty much anywhere they can attach their nest “building materials.” Hornets make their own nesting material by mixing chewed-up wood pulp from tree bark mixed with their saliva, forming an enclosed nest around the comb where the queen lays her eggs.

Hornets nests can grow quite rapidly, with a surprising number of hornets living in what we would consider cramped quarters. Often, homeowners don’t even realize that they have a wasp infestation until the nest grows to a decent size, especially if the nest is formed in an area of the home or surrounding property that isn’t visited too often. Often, by the time a Cowleys tech is called out to the home, the nest has grown to the size of a melon. Once these guys get going building their nest, they mean business. Nest sizes can double in just a week!

These particular homeowners in Toms River, NJ called us after discovering a hornet's nest that was built, of all places, on the side of a raised playhouse in their yard. Fortunately, no one had yet been stung, but this was a potentially dangerous situation. Hornets usually don’t go out of their way to bother anyone. The problem is when someone unknowingly walks into the path of foraging wasps. With kids playing around this structure, there was a high risk of a swarm of wasps stinging children. This nest was not noticed immediately because it was built pretty high up on the playground— about twelve feet up a side wall of the structure. 

To treat this hornet infestation, I used an aerosol pyrethrin application attached to an extension pole to access the nest. After spraying, I waited for about 20 minutes for the application to take effect. This product immediately knocks down the wasp population, and after waiting, there were no more visible wasps swarming around the nest. Now, with a nest that was substantially inactive (of course, there could always be a few live wasps still hiding in the nest), I removed the nest with a scraper attached to the pole. I then bagged the nest to take it off the property. Finally, I treated the area where the nest was attached that would help prevent the Hornets from trying to reconstruct the nest. 

This type of stinging insect assignment is very satisfying to me. When finished, I knew that by removing this nest, I likely prevented some innocent kids from being attacked by a swarm of hornets just because they happened to be in the wrong place at the wrong time.

Recently, I was called out to help homeowners in Toms River, NJ, who were having a troublesome mouse infestation problem. As temperatures drop, rodents will seek to overwinter inside our warm houses to escape the harsh outdoor elements. Their very survival depends on it. The objective for a homeowner is to eliminate potential entry points into your home so they go elsewhere. Mice will find the tiniest gaps, cracks, and opening around the foundation to enter the basement or crawl space and once inside, they have no problems traveling through wall voids throughout the home, usually winding up in the kitchen foraging for food debris.

Conducting a careful exterior perimeter inspection, I determined how the mice were getting in. Mice only need an opening around the diameter of a dime, so you have to be systematic and methodical, inspecting every inch of the perimeter. Here, I found holes in the crawl space vents and access door as well as spaces in the garage door jambs (the trim around the perimeter of the garage door that helps keep out insects and small critters. Because this trim is exposed to the elements, they are susceptible to splitting, rotting or warping, creating an opening for pest entry. I sealed the openings with an expandable foam, and also set up some rodent bait traps in strategic locations. I set up a two-week follow up to re-inspect and check the bait in the traps to determine the level of rodent activity. With the access points blocked and traps set, this mouse infestation should be quickly resolved.

A homeowner in Lincroft had been dealing with mice in their basement, attempting to handle the problem on their own for quite some time. According to the homeowner, they would trap some mice, and drive them 4-5 miles away to a wooded area, and release them. Thereafter, new “replacement” mice would soon appear. This cycle went on for a while. Finally, they decided that their DIY plan of action was not working, and they contacted Cowleys for a permanent resolution of the problem. 

A mouse infestation will not be resolved unless and until their access points into the home are identified and sealed. Without doing this exclusion work, you’ll be in the same situation as these homeowners and dealing with a never-ending stream of mice. Also, I pointed out to the homeowners that, although they had good intentions by not immediately killing the mice, they did not do them any favors by releasing them into a strange area. These relocated mice would likely die because they don’t know where to find adequate food, water, or shelter in their new surroundings, and in their weakened state would likely succumb to predation. 

Upon arrival, after speaking with the homeowners, I grabbed my flashlight and began my inspection. Finding the access points for mice presents a challenge for pest control technicians, especially if they really want to do the job right. Unlike larger wildlife that will use of carve out readily noticeable entry points into the home, mice can get through extremely small cracks and gaps. Because of their fur, mice are even smaller than their appearance. They only need a 1/4" diameter hole (about the size of a dime) to squeeze through. Mice don’t have collarbones. The rule of thumb is that if a mouse is able to poke its little head through a hole, the rest of their body will follow.

Looking for any potential entry points, I thoroughly inspected the basement perimeter, paying careful attention to any gaps around utility pipes or wires going through the foundation wall. These are often the preferred entry route for mice. I found two areas of concern: A PVC pipe discharge line from the sump pump and an outdoor water spigot. Both had sizable gaps that would easily allow rodent entry. 

Before laying out my equipment that I’d be using to control the mice, I first grabbed my hepa-vac to vacuum up all of the rodent droppings. Mouse droppings are toxic, and may contain many dangerous pathogens, including hantavirus. When the droppings dry out, spores can become airborne if the droppings are disturbed, creating a potential health hazard, especially in an enclosed area like a basement. After cleaning the area, I set up some rodent bait stations around the sill plate in the basement, dusted the two openings with a tracking powder, and sealed the holes from the outside with copper mesh. 

The homeowners were relieved that they would no longer be dealing with mice, a problem that had been going on for far too long. 

I was sent to Middletown, NJ with my colleague Alfonso to help a homeowner who had contacted Cowleys after finding mouse droppings in several areas of their home. With any rodent infestation, our priority is finding any actual or potential entry points. Finding mice entry points is a challenge since they can squeeze through the smallest of cracks and crevices. A mouse needs only about a quarter-inch gap to find their way inside your home. If a mouse is able to poke its snout through a hole, the rest of its body will follow. To successfully resolve a mouse infestation, it is critical that these entry points are located and sealed. Failure to do so means that you’ll likely have ongoing problems with these overwintering pests, even if the ones already in your home are eliminated. 

As outdoor temperatures drop, mice, other wildlife, and certain insects will look for harborage in your home to escape the harsh outdoor elements. if there is a weak link for them to gain access inside your home, they’ll find it. Mice commonly look for entry points around the home’s foundation. They’ll enter into the crawl space or basement and then find their way to the living areas of the home when they forage for food and water. One of the most common, and often overlooked, entry points for mice are pipe chases, those spaces where pipes, such as from air conditioning units and the home’s plumbing system, as well as electrical supply lines, are run into the home. Pipe chases often become entry points for overwintering mice and bugs when the original sealant around the pipes starts to become worn and disintegrates, creating a perfect “tunnel” for pests to enter the home. We found several possible entry points around some pipes, and sealed them with chew-proof copper mesh. To reduce the mouse population in and around the home, we set up rodent control bait boxes in the home’s interior as well as the exterior perimeter. Finally, as part of our protocol, we scheduled a two-week follow-up to re-inspect and replenish the bait boxes as necessary. We are confident that with the exclusion and the bait boxes. We’re confident that it won’t take long for the infestation to be resolved, and this homeowner will no longer find droppings and other upsetting signs of mouse activity in his home.
