Pests We Treat Before & After Photos

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.

A new customer in Colts Neck, NJ called our office after finding a large yellow jackets nest in the attic of his detached garage. As we inspected the attic we found the large, and active, yellow jackets nest tucked in the corner! For treatment, we injected a knockdown aerosol application, waited several moments, and then injected a knockdown dusting application. Both of these applications rapidly exterminate the yellow jackets. 

Once they were eliminated, we removed the nest, disposed of it properly, and cleaned the area. 

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.
