Pests We Treat Before & After Photos

I was sent to Holmdel, NJ to help homeowners who were dealing with a mouse infestation in the void above their basement ceiling. After finishing up exercising on their basement treadmill,  the homeowners heard some strange noises above their heads — the scratching and scurrying noises of mice above their heads. Mice prefer to stay away from well-lit areas and stay in out-of-the way places like wall voids and above ceilings where they can come and go and move around the house as they please. When things are quiet, these sounds tend to amplify, and often, homeowners think that they are dealing with a much larger problem like squirrels or even raccoons. Of course, no homeowner should ever think that it’s “just mice.” Mice and their urine and droppings can contaminate food and counter tops. Like any wildlife, they are a health risk to a home’s occupants.

Needless to say, the homeowners were right. Mice had entered their living space from outside. Mice usually enter homes around gaps and cracks in the foundation, and I began my inspection in the basement, first popping out some tiles near where they had heard the unwanted visitors so I could get a better look. There were some mice droppings on to of the ceiling tile. I immediately saw how the rodents were gaining access. There was some daylight coming from a small opening on the outside wall. There was a hole drilled through the foundation, possibly for a exterior water spigot. However, nothing was ever installed and the hole was never sealed. Mice exploited the opening and came into the home.  Mice only need a hole about the size of a dime to squeeze through. These rodents are even smaller than they look because of all their fur. They have no collarbone, so if they can stick their head through an opening, the body will follow.

I always carry disinfectant and a hepa vacuum with me. I first sprayed the the droppings before cleaning them up. It is dangerous to disturb dry droppings because microscopic particles containing dangerous pathogens like potentially fatal hantavirus are released into the air.   

Preventing entry is key to rodent control. I stuffed the entry points with copper mesh that rodents are unable to chew through. Finally, I secured a rodent bait box on the home’s exterior near the hole. The combination of these strategies will soon put an end to the mouse problem for these homeowners. 

Recently, I was dispatched to a home in Holmdel, NJ that was having a problem with some “large wasps” that had taken up residence, of all places, behind the slats of a hot tub. Upon, arrival, I immediately determined that these homeowners were dealing with a European hornet infestation. These are one of the larger stinging insects that we regularly encounter. They can grow to about one inch long, making them one intimidating stinging insect! Because these insects have some yellow in their markings, they can be easily  confused with yellow jackets. However, they are much larger, thicker insects than the slender yellow jacket. Also, unlike yellow jackets, European hornets usually has some orange in their coloration. Like all social wasps and hornets, European hornets are aggressive and territorial if they perceive that they are being threatened. As far as stinging insects go, both yellow jackets and European hornets are similar in that they both have nasty temperaments and won’t hesitate to use their stingers. 

Unlike baldfaced hornets, paper wasps, and other stinging insects, European hornets rarely build suspended nests attached to tree limbs, roof eaves, and other locations in plain view. Instead, just like they did here, these insects usually build their nests inside a hole or cavity. The location of their nests can make them difficult to reach and treat. Sometimes, these hornets will enter homes for shelter, finding entry point through eaves and vents where they then form nests, commonly in wall voids and in attics.  

Here, I promptly located where these hornets were nesting inside the hot tub. First, I treated the nest with a dust that quickly knocks down the population. After waiting until I observed no more active insect activity, I successfully removed the nest. As shown in the photo, the nest was broken into numerous pieces because I had to pull the nest out piecemeal from inside the hot tub. Since the nest was cracked open, you can clearly see the hundreds of combs inside the nest that housed the hornet larvae. I collected all of the nest pieces, bagged them, and took everything with me so there was no remaining nest debris. Now, these homeowners can resume the use of their hot tub without feeling threatened by these large stinging insects.

We were sent out on a service call to a business in Toms River, NJ to treat for wasps that were attacking the shoppers as they made their way into the store! Once we arrived, we inspected the area more closely and discovered a baseball sized yellow jackets nest right above the entrance!

As we all know, yellow jackets are one of the most aggressive and territorial stinging insects out there! So extreme care is needed when treating them. So we equipped our protective bee suit, grabbed our extendable pole, attached a knockdown dusting application to it, and began liberally treating the nest. A few moments later, we treated the nest with a knockdown aerosol product. Both of these treatments quickly exterminate the yellow jackets.

After a few moments went by, we removed the nest, disposed of it, and then applied a residual liquid application to the area. This product will eliminate any yellow jackets that return to this area as well as prevent them, and all other stinging insects, from building another nest.

A new client in Toms River, NJ frantically called our office after finding a rat in her basement. So we were sent out to inspect and treat. During our inspection, we noticed a rather large gap where the water line was entering the structure through the foundation wall. As we took a closer look, we found several rat droppings right below it.

First, we carefully cleaned up the rodent droppings and installed several rodent bait stations throughout the basement and along the exterior of the home. Next, we stuffed the opening with chew-proof stainless steel mesh, which rodents hate chewing through. Afterward, we sealed the opening with a waterproof, premium adhesive. Lastly, we scheduled several follow-up visits to replenish the bait in the stations and monitor the rat activity. 

Recently, a was sent to a residence in Howell, NJ. The homeowner had contacted Cowleys after a surprise run-in with two mice in the kitchen the night before. Since mice are nocturnal, if these is a mouse sighting, it is usually at night when they are doing their foraging. Mice are experts at staying hidden and you’ll usually find signs of mouse activity like droppings, nesting materials, and relocated food well before observing the rodents themselves. Also, mice don’t travel far from their nest and they are not loners. Mice live in groups known as a horde or mischief of mice, so if you see one or two, it’s a safe bet that there are quite a few others hiding in the wall voids or behind your kitchen appliances. 

I first checked the basement. Often, mice first gain entry through gaps and cracks around the foundation. The perimeter of he home appeared well sealed with no obvious entry points. Asking the homeowner, where he saw the mice running to before he lost sight of them, and he said they had scampered from a closet to underneath the refrigerator. Mice commonly nest underneath refrigerators because the area is well hidden and warm from the motor. Here, I moved the fridge to look behind and there were no openings in the wall behind. Next, I checked out the closet, and found a hole in the wall along with mice droppings in the area. When these mice weren’t foraging for food in the kitchen their home was a wall void that they accessed in the closet. 

I temporarily sealed the hole with chew-proof copper mesh until the homeowner could permanently have the hole patched. I also placed rodent stations in the closet, and for good measure, also put two rodent stations in the basement. Upon a closer exterior perimeter inspection, I found one potential crack that could have ben used to gain entry into the home. I also sealed this opening with copper mesh and also set up another rodent station nearby.  With these internal and external holes closed, the mice infestation should resolve. I told the homeowner to contact us if he saw any new signs of mouse activity, and we would be out there again for a follow-up.
