Pests We Treat Before & After Photos

Cowleys handles all of the pest control needs of a community of homes in northern Howell, NJ. Recently, I was contacted by the property manager and asked to inspect and treat a resident’s home for ants, and did so. Whenever I am at a residence, I always perform an exterior perimeter inspection for pest activity. Often, we uncover a pest infestation that the homeowner had no idea was lurking right outside their door! 

Here, I came across an active bald-faced hornets nest. The homeowner was shocked that he missed their activity. These particular wasps are close relatives of yellow jackets and they are just as nasty and aggressive, singing anyone or anything that comes into the “danger zone” around their nest. These wasps, unlike bees, can sting repeatedly, so a swarm of them can pose quite a dangerous situation.

Bald-faced hornets often build their paper-like nests of chewed wood mixed with their saliva in shrubs, trees, and sheds, usually 3 to 4 feet off the ground. They also will attach their nests right onto homes. Here, the wasps built their nest in the overhang between the soffit and gutter. In late summer, insect activity is at a peak since they have been active for quite awhile and you’ll start seeing some large, mature colonies with potentially hundreds of workers. 

During the day, these nests are exceptionally active with workers hovering about the nest, flying in and out. It’s pretty much impossible to sneak up on them, so treating these nests must be done carefully. I did not want to take any chances and put on my protective bee suit. First, I sprayed the opening of the nest with a foam that kills the wasps almost instantly. It is important to quickly knock down the population as fast as you can once you rile them up. I waited a few minutes for the product to work. After I saw no more activity, I removed and bagged the nest, taking it with me off the property. It is important to remove all remnants of activity so that other insects are not attracted to the same area. 

The homeowner was thankful that I located and treated this wasp infestation before anyone was stung.

I was sent to a home in Cliffwood, NJ when the homeowner contacted Cowleys after finding a wasp nest above a window in a seldom used room. 

Upon arrival, I went to the room where there was a wasp nest. Based on the shape and construction of the nest, i immediately recognized it as a mud dauber nest. Mud daubers are solitary wasps that, unlike social wasps like yellow jackets and baldfaced hornets, do not live in colonies with a queen and hundreds of specialized workers. Instead, each female breeds and tends to her own. For the most part, solitary wasps like mud daubers are not territorial with regard to their nests. They  are not aggressive, and they seldom sting people. 

These wasps also known as dirt daubers or mud wasps, and for good reason. The female constructs small nests by carrying little mud balls to the nest site. She uses the nests to keep her eggs warm. The nests are built as cylindrical tubes that look like a pipe organ (the most common species in New Jersey is known as the organ pipe mud dauber).

I removed the active nest that already had several eggs and wasps in various stages in their life cycle. Homeowners can control mud dauber populations in their home by controlling spider populations since they live, for the most part, on a steady diet of spiders. By sealing cracks where spiders can live and regularly removing spider webs, you should not have a problem with mud daubers. However, if you do start seeing these strange little mud nests around your home, call a pest control technician to remove them. While these guys are not actively looking to sting, if you start trying to scrape away their nests as a weekend DIY project without the right equipment and products, you’re asking for trouble. 

Recently, I was sent to a home in Millstone Township, NJ for a periodic inspection and service visit that’s included in our residential home protection plans. These plans are valuable to homeowners because we often uncover pest problems that are overlooked by homeowners, especially outdoor infestations and infestations in their early stages. 

During my inspection, I observed a hornet just starting to make a nest on an overhang of the front door. Hornets are highly territorial insects and a nest in any high pedestrian traffic area is a problem. If this nest was not removed, residents and guests of this home could easily be perceived as a threat to the nest and suffer the consequences. Hornets are a formidable threat since they often attack as a swarm. Their venom is especially painful because it contains high levels of acetylcholine, a chemical that stimulates our pain receptors. Also, a single hornet is able to sting multiple times because, unlike bees, its stinger remains intact and does not become lodged in the victim. Since hornets are large insects, they carry a good supply of venom, and release more venom per sting than any other stinging insect. Suffice it to say, I was glad that I was able to locate and treat this nest while it was still in its beginning stages of being formed. By removing this nest now, this household avoided a serious stinging insect threat. 

Fortunately, since the nest was just starting to be formed it did not pose much of a threat to remove it. And that was just fine with me! First, I sprayed the nest with an aerosol foam to knock down any hornets in the nest. Once I saw that there was no more live activity, I safely removed the nest, bagged it, and carried it with me off the property. The homeowner was quite appreciative that I caught this problem early on before the hornets had a chance to form a mature nest. 

As I was performing a routine service for a Home Protection Plan customer in Keyport, NJ I noticed a viable entry point in the foundation of a house. Believe it or not, this opening is the perfect size for not just pests, but mice to enter the home. In fact mice can squeeze through an opening the size of a dime!

First, I stuff the opening with copper mesh. Copper mesh is an excellent way to exclude rodents from crawling into tights spaces because they are unable to chew through it. Next, I used black caulk to seal the opening. Afterwards I finished treating the home for their regular service. 

One warm afternoon in Manahawkin, NJ, this homeowner and his teenage son were getting some much needed yard work done. As the teen was mowing the lawn, he was suddenly attacked and stung by several hornets! He quickly stopped what he was doing, told his Dad who then called Cowleys for help and we were sent out to investigate and treat. 

As we inspected the area where the teen was stung, we took a look at the large tree and spotted the hornets nest. Upon closer inspection, we were able to identify them as 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. Aside from being short-tempered and extremely aggressive is they have smooth stingers, which means they can sting over and over again, can actually sense vibrations in the air, and remember their invader's face!

To eliminate them, we injected a knockdown dusting application directly into the opening of their nest. After several moments, we also injected a knockdown liquid application. These treatments will exterminate the bald-faced hornets almost immediately. A short while after neutralizing the bald-faced hornets, we removed the nest (and the branch it was attached to) and disposed of them.
