Pests We Treat Before & After Photos

Recently, I went out on a service call for one of our commercial clients, an apartment complex in Belmar, NJ. The property manager had contacted us after a tenant in one of the lower-level apartments reported a mouse infestation. Mice are more than a nuisance. They pose a significant health hazard. Mice can contaminate food and counter surfaces with their urine and droppings, particles of which can become airborne.  Mice can transmit numerous diseases including Hantavirus Pulmonary Syndrome (HPS), a severe, sometimes fatal, respiratory disease and Lymphocytic Choriomeningitis (LCM) that affects the membranes of the brain and spinal cord. If that weren’t enough, they often carry in Lyme-carrying ticks or disease-ridden fleas with them as well.

Once I arrived, I began my inspection along the exterior perimeter of the apartment where mice were reported to locate potential entry points. I discovered many access points where the mice could easily enter the structure. There were spaces around piping entering the building, gaps around the windows and doors and a large space between the soil and the landing to the staircase leading upstairs. 

As I continued my inspection inside the garage and apartment, I came across a large number of mouse droppings. This unit had a heavy rodent infestation that required extensive treatment.

With rodents, it is essential to keep them out in the first place by excluding any areas where the rodents are gaining access. I stuffed chew-proof copper mesh material into small spaces around pipes and sealed the gaps around the larger holes with metal flashing. Mice hate the taste and feel of copper mesh, and once they come in contact with this material, they quickly decide to go elsewhere. 

After all the points of entry were sealed, I placed several rodent bait stations throughout the property. Typically, the number of rodent bait stations we use depends on the severity of the infestation. In this case, I set up twelve small rodent bait stations in the inside of the apartment and one larger station along the exterior perimeter. After placing all rodent bait stations, I carefully removed all of the hazardous mouse droppings.

Due to the severity of this infestation, it will take longer than usual to rid this apartment of mice. I scheduled periodic follow-ups to monitor the level of infestation and replenish the bait in the stations until this mouse problem is completely resolved.

After setting up our rodent bait stations to get a handle on the mouse infestation at this home in Sea Girt, NJ, we're returning for a follow up visit. After we replenished the bait in all the stations, we stuffed all the access points with chew-proof metal mesh. Rodents typically don't like chewing through metal because it's extremely uncomfortable for their teeth and gums. Next, we sealed all the openings with a premium, waterproof adhesive. The combination of the two materials makes for a great deterrent. We'll return for a few more follow-up visits to monitor the mice infestation and replenish the bait stations as needed.

This homeowner in Spring Lake, NJ had ants all over her kitchen counter, so she called our office and we were sent out to inspect and treat. When we inspected the interior, we found some ant activity on the kitchen counter, but nothing too large. It wasn't until we went outside and found ants trailing from her garbage cans into the kitchen. The homeowner immediately started to clean out hr garbage cans and move them away from her home.

In the meantime, we applied a gel bait to the ant trails on the kitchen counter and treated the baseboards, cracks, and crevices in the kitchen and the two adjacent rooms with a liquid non-repellent. Afterward, we went outside and applied a granular bait to the grassy areas and then treated the entire exterior with a liquid residual. The ants will bring any of these treatments back to their nest and share them throughout their colony.  A short while later, the ants are extreminated.

Recently, a homeowner in Spring Lake, NJ, contacted Cowleys because a hornet nest had formed on the soffit of her home. It was built fairly high up, so it wasn’t a major threat. Hornets can be aggressive and territorial and will attack if their nest is threatened. Here, there wasn’t much traffic around the nest and everyone was a safe distance away. The homeowner’s concern was that the hornets would gain access inside the home through the attic. To avoid this and any other issue with these stinging insects, I proceeded to remove the nest.

Hornet nests have an entry hole where the foraging wasps enter and exit. I watched their flight pattern in and out of the nest and set up my extension ladder on the opposite side of their activity. I had no interest in meeting these wasps head-on! I climbed the ladder and treated the nest with an aerosol that quickly knocks down the population. I then waited until the wasp activity dramatically slowed down. I reached by nest with the bee pole and gave it a good wack to knock it to the ground so that I could bag it and take it with me off the property. The homeowner was relieved that this nest was removed off her property. There are some people that have no tolerance for stinging insects, and this homeowner was one of them! I was glad to help.

Recently, I was sent to a home in Spring Lake, NJ, to resolve a mouse issue in the kitchen. This was an older home that had an old-fashioned bread drawer (breadbox) with a tin cover. For those of us who have been around awhile, they were once commonly found in kitchens. Now, with breads being made commercially with food preservatives and wrapped in plastic, we rarely see them installed in modern kitchens. 

According to the homeowner, the bread drawer cover had rusted away, giving mice easy access to the bread. There were holes chewed through the dread bag and mouse droppings in the drawer. Any time there is a mice infestation in the kitchen, there is a risk of food contamination from their waste, and it is important to resolve this health hazard quickly. I inspected the other parts of the kitchen cabinet, but mouse activity was limited to the bread drawer. Apparently, with a ready and accessible supply of food in that drawer, there was no need for them to forage elsewhere. 

Usually, rodents enter a home around the foundation.They find gaps and cracks, often around gas or water pipes entering the home where the sealant has deteriorated. Once inside the basement or crawl space, the wall run along the sill plate (the wood closest to the ground on the top of the foundation walls) until they find a way to gain access to the living spaces of the home up above. Here, I found a gap around the sink drain under the cover plate (escutcheon plate), the base plate disc around water pipe at the wall penetration. These plates are visible around faucets and tub or shower fixtures, but plumbers also use them around sink drains. I sealed the gap with a chew-proof copper mesh. I also found mouse droppings on a ceiling tile.

I set up mouse bait stations under the kitchen sink as well as several points on the basement sill plate where there were signs on rodent activity. I scheduled a two-week follow-up inspection in two weeks to re-inspect and determine additional treatments as needed to get this mouse problem resolved.
