Pests We Treat Before & After Photos

During a routine treatment of this restaurant in Princeton Junction, NJ, we noticed a few fruit flies flying around one of the floor drains. We took a closer look and found a large amount of fruit flies inside of it! Turns out the fruit flies were attracted to rotting produce inside the drain. For treatment, we applied a liquid application and then scrubbed the floor drain out with our heavy-duty scrubbing brush. This application removes the bad bacteria in the drain, which is the breeding ground for the fruit flies.

Afterward, we applied a bio-foam solution in the floor drain. This product removes all the organic build-up, odors, and scum inside them. Lastly, we applied a fly bait to the area around the floor drain to exterminate any remaining adult fruit flies. Before we left, we suggested a few simple sanitation procedures to the owner to prevent any future fruit fly infestations. 

During a summer treatment service for this Home Protection Plan customer in Plainsboro, NJ we noticed that one of outlets near the deck had an active yellow jackets nest inside it! Yellow jackets are aggressive, territorial wasps, with distinctive yellow-and-black coloration, that are known for their propensity to sting anyone and anything that they perceive as a threat, such as those who venture too close to their nests or their food.

In order to rapidly exterminate the yellow jackets, we used a knockdown aerosol application. Once the yellow jackets were eliminated, we removed the nest, disposed of it, and cleaned the area.

With mice and other nuisance wildlife infestations, it is critical to find the potential entry points and seal them; otherwise, the infestation will never be permanently resolved. 

We carefully inspected the entire home, filling every hole we could locate with  spray foam. The before/after pictures highlight that the gaps that were once open are now closed off. During my inspection, I also noticed a large gap underneath the front door that would allow mice to enter. I installed rubber weather stripping to seal that potential route. 

I was sent to a home in Bridgewater, NJ who’s owner was walking to their car when he noticed a huge gray hornets nest in the tree adjacent to the walkway. 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. 

First I want to say, it’s a good thing he did not try to remove it himself. These hornets are extremely aggressive, and will defend its nest if threatened. They 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. 

I quickly put on my bee suit. With these particular stinging insects, I wasn’t going to take any chances. With the protection of my bee suit, I was able to I walk right up to the nest, and find the entry hole.

Once found, we inject a foaming insecticide directly into the nest, quickly paralyzing all of the hornets and any stray hornets that might be returning from gathering nest building material.

Once I was sure that there was no further danger from those hornets, I removed the nest from the branch, and let the homeowners know to stay away from the area for a while because there still could be returning hornets wondering where their home went. Eventually the hornets would go elsewhere.

As this elderly homeowner in South Bound Brook, NJ was walking around the exterior of his home, he discovered a HUGE bald-faced hornets nest in one the bushes! He ran inside and called Cowleys for help!

We arrived, equipped our protective bee suit, and within minutes located the bald-faced hornets nest (it was hard to miss)! When a hornets nest gets that big, it means there are hundreds of short-tempered insects inside waiting to sting anything that comes close to their nest! For treatment, we injected a knockdown aerosol application directly into the opening of the nest. A few moments later, we treated the nest with a knockdown liquid product. Both treatments rapidly exterminate the bald-faced hornets. Once they were eliminated we removed the nest and the branch it was attached to and disposed of them properly.
