This homeowner in Princeton, NJ found herself with bats nesting under the fascia leaving guano (the excrement of birds and bats) deposits all over the deck. Bat guano happens to be an excellent organic fertilizer because of its high nitrogen and phosphorus, but it is also a health hazard. Bat and bird guano can contain numerous pathogens including  a fungus that causes histoplasmosis, a serious chronic lung disease, and exposure, Including breathing in these airborne particles, is dangerous for homeowners. Also, bats are major carriers of rabies. Bat infestations need to be removed and professional experienced in excluding bats from nesting in your home should be brought in. This is not a DIY project and you should not be working in a bat-contaminated area without proper protective equipment. For this home, I completely covered the fascia with a metal barrier to keep them from roosting in and between the fascia board.

Job Stories From Princeton, NJ
Yellowjackets high up in Princeton, NJ

I was servicing a regular client in Princeton. I went directly to the unit that was having the issue with the yellowjackets. The resident was even seeing the stingers in her unit. I inspected the exterior and quickly found a nest in the roof sheathing by the gutter. I proceeded to treat the opening with a dust insecticide.

Citronella ants invade Princeton, NJ crawl space

Cowleys received  a call from a Princeton homeowner who had been seen “a small army” of  yellow ants in his crawl space and all over the vent cover leading into the crawl space. These particular ants are citronella ants, and get their name from the citronella odor that they emit when threatened or crushed. These ants feed on the excretion of aphids and mealybugs that feed on the roots of shrubs, and the swarmers (winged ants), which are much larger than the workers, are frequently confused with termites.

Upon arrival, I inspected the crawl space and immediately came across a customer DIY moisture barrier. Unfortunately, weekend handyman projects usually don’t have the same results as professional installations. That was clearly the case here. The crawl space was humid and filled with moisture, and this barrier, a jerry-rigged tarp, was doing little to stop moisture and humidity from entering the crawl space. Upon further inspection, I noticed citronella ants surrounding the outer areas of the tarp. I rolled up part of the tarp, which was loose, to better inspect the area and observed numerous citronella ant trails criss-crossing the crawl space.

I treated the crawl space as well as the exterior of the home. In addition, I spread a granular bait that the ants will pick up and bring back to the colony, killing the queen. With the queen dead, the entire colony will soon eliminated. Killing a few foraging ants will not stop the infestation. To successfully resolve an ant or other insect infestation, you must kill the colony.
