Cockroaches are among the most common complaints in older northeastern cities, and Newark is no exception. Buildings share walls, plumbing risers and basement boiler rooms, and warm radiator heat in winter means roaches stay active when other insects have gone quiet.
The species behind the problem
German cockroaches are the main indoor offenders in Newark apartments. They are small, reproduce fast, and ride into buildings in grocery bags, cardboard boxes and used appliances. American cockroaches prefer sewer lines, steam tunnels and warm basement areas, and are often seen in older brick buildings. Oriental cockroaches, sometimes called water bugs, like cool, damp spots such as cellars, drains and the area under leaking sinks.
In the Ironbound, restaurants and bakeries produce plenty of food waste, so rear alleys and shared walls can feed building-wide infestations. In the Central Ward and North Ward, aging multi-family houses with wet basements are common roach harborage.
Where the trouble hides
- Behind refrigerators, inside range hoods and under dish racks.
- Within wall voids around plumbing pipes, especially in kitchens and bathrooms.
- In boiler rooms, laundry rooms and trash chutes in apartment buildings.
- Inside cardboard storage, which provides food and shelter.
What professional treatment includes
Licensed pros begin with monitoring and inspection to identify species, locate harborage and plan baiting. For German roaches, gel baits, bait stations and insect growth regulators are the usual tools, with minimal spraying. Technicians also fill gaps around pipes and cabinets. For American and Oriental roaches, treatment may focus on basements, drains, sewer connections and the building perimeter, including sealing foundation gaps and door sweeps.
In multi-family buildings, treating just one unit is rarely enough. Cooperation with neighbors and landlords is critical, and a rotating schedule of follow-up visits usually accompanies the initial service.
Timing and persistence matter with roaches. A first visit knocks numbers down, but nymphs keep hatching from egg cases for weeks, so follow-up visits are what finish a job. Residents who throw out bait stations, scrub away gel placements or spray over treated areas undo the work. If you see more roaches for a few days after treatment, that is often because bait is drawing them out of hiding, not because the service failed.
Making your unit less appealing
- Wash dishes nightly, and avoid leaving dirty pots on the stove.
- Store dry food in sealed containers and recycle cardboard promptly.
- Fix leaky faucets and wipe sinks dry before bed.
- Caulk gaps around pipes under sinks and behind radiators.
- Check bags and boxes brought in from outside.
Landlords, tenants and shared walls
In Newark rental buildings, tenants usually have the right to ask the landlord to arrange pest control. Document your request, take photos, and let the manager know the apartments that share walls with yours. Property owners benefit from scheduling building-wide inspections so that unreported units do not keep the population going.

Roach questions in Newark
Why do I see roaches in winter?
Heated buildings keep them active. Steam heat and warm pipes provide a stable home.
Should I use over-the-counter bombs?
They tend to scatter roaches and leave residues. Baits placed by a professional are normally more effective.
How can I tell if roaches came from the neighbors?
If sightings continue after your unit is treated, or roaches are near shared walls and pipes, neighboring units may be involved.
Are cockroaches linked to health issues?
Their shed skins and droppings can trigger asthma and allergies, particularly in children.
