Seeing roaches dart across the kitchen counter at night is one of the most stressful things you can deal with at home. Pest Control TC is a family-run exterminator, and we treat cockroaches in apartments, co-ops, condos, older homes, and restaurants across the areas we serve. Most calls get a fast, often same-day appointment.
The German cockroach is the roach we treat most. A large share of households in dense, multi-unit buildings deal with them because shared walls and pipes let them move between apartments. That is why a spotless kitchen still gets re-infested, and why a quick monthly spray rarely fixes the problem.
Our work is built on Integrated Pest Management: inspect, identify the species, place targeted gel bait and dust where roaches actually hide, then follow up until the colony is gone. It keeps spraying to a minimum, which matters in homes with kids and pets, and it works far better than bombs and store sprays. We give upfront pricing and work with both renters and owners or boards. Request a free estimate or book a consultation online.
Pests We Treat and Eliminate
Cockroaches We Treat (and How to Tell Them Apart)
Knowing which roach you have changes the whole fix. Almost every stubborn apartment infestation is the German cockroach. The big bugs people call water bugs are usually a different species that wanders in rather than breeds inside.
German Cockroach: The #1 Apartment Roach
About a half inch long, light brown to tan, with two dark stripes running down the back behind the head. It breeds indoors in warm, humid kitchens and bathrooms. One female and her offspring can leave thousands of descendants in a year, with roughly 30 to 40 nymphs per egg case. Many populations now resist the pyrethroid sprays sold in stores and used in building contracts, which is a big reason they keep coming back.
American and Oriental Cockroaches (the Water Bugs)
American roaches are large and reddish-brown, up to about 1.5 inches. Oriental roaches are shiny and almost black. Both come up from basements, drains, sewers, floor drains, and compactor rooms, and they do not colonize living space the way German roaches do. The fix is exclusion and sealing: drain covers, copper mesh in gaps, and controlling moisture, not kitchen gel bait alone.
Brown-Banded Cockroach
Smaller, and it tolerates drier, warmer high spots: upper cabinets, behind picture frames, and inside electronics and appliance motors. Less common, but treated with the same targeted baiting.
Water Bug vs. Cockroach: What You Are Really Seeing
- A large, fast, lone brown bug near a drain, tub, or basement at night is almost always a wandering water bug (American or Oriental).
- Several small, striped, half-inch roaches in the kitchen or bathroom mean a breeding German cockroach colony.
- Water bugs wander in and need sealing and exclusion. German roaches live and reproduce inside and need gel baiting and an IGR.
Signs of a Roach Problem and the Health Risks
Roaches hide during the day, so a few clues usually show up before you ever see one. Catch them early and treatment is faster and cheaper.
- Live roaches in daylight, which usually signals heavy numbers
- Pepper-like droppings or dark smear marks in cabinets and along baseboards
- Small brown egg cases (oothecae) glued into corners and seams
- A musty, oily odor in bad infestations
- Shed skins near hinges and motor housings
- Where to look: under the sink, behind and under the fridge and stove, cabinet hinges, and inside appliance motors
Why Roaches Are So Hard to Beat in Apartments
German roaches spread through shared wall voids, pipe chases, and electrical lines, and older buildings give them deep, hard-to-seal hiding spots. A clean unit gets re-infested from a neighbor, the building's trash or compactor chute, or an adjacent ground-floor restaurant. Add fast reproduction and pyrethroid resistance, and one-shot fixes simply do not hold.
Why Your Building's Monthly Spray Is Not Working
Most building and super contracts cover a quick baseboard spray. Modern German roaches are widely resistant to those pyrethroid sprays and treat them as a repellent, so the colony scatters deeper into walls and into neighboring units. Worse, the spray contaminates and repels gel bait, the one thing that actually works. Real control means targeted gel baiting, an insect growth regulator to stop reproduction, and crack-and-crevice dust, not perimeter spraying.
Roach Season: Summer Surge, Year-Round Breeding
June through September brings a surge as heat and humidity speed up breeding. But heated apartments keep German roaches reproducing all winter, so they never truly clear out on their own. Late spring and early fall are strong windows to break the cycle before or after the peak.
Why DIY Sprays, Foggers, and Roach Bombs Fail
Total-release foggers and bombs sound aggressive, but they coat open surfaces where roaches barely go and never reach the cracks and wall voids where the colony lives. They can scatter survivors deeper into the building and into neighboring units. Store sprays repel roaches and ruin any bait nearby.
The entomology is settled: many small gel-bait placements plus an IGR beat one big spray every time. That is the core of how we treat German roaches, and it is why professional baiting succeeds where the can under your sink does not.
Building-Wide and Floor-Level Treatment for Co-ops, Condos, Rentals, and Restaurants
Because German roaches travel through shared wall voids, pipe chases, and the compactor chute, treating one unit alone often is not enough. We coordinate simultaneous treatment of stacked and adjacent apartments, work directly with boards, supers, and property managers, and offer discreet, unmarked service so neighbors are not alarmed. Our residential and commercial programs can run side by side in mixed-use buildings.
Restaurants and Units Above Food Service
A ground-floor restaurant is a steady roach source for the apartments above and beside it. We run health-code-conscious monthly programs for food-service kitchens and coordinate with nearby residential units, so the problem does not bounce back through the shared walls and chases.
Before and After Your Roach Treatment
How to Prepare (Tenant Checklist)
- Empty and wipe down kitchen cabinets and under-sink areas
- Clear clutter, especially cardboard boxes and paper bags
- Take out the trash and fix any leaks or standing water
- Clean thoroughly so the bait competes with less food
- Do not spray store insecticide beforehand, since it pushes roaches away from the bait
- We send a full checklist when you book
What to Expect After
You may see more roaches for a few days. That is normal and a good sign: the bait draws them out of hiding to feed, so you will notice sluggish or dying ones. Do not spray, do not wipe away the gel bait, and hold off on deep-cleaning treated cracks. Keep your follow-up visits so newly hatched nymphs get hit too.
How to Keep Roaches Away
- Clean the kitchen nightly, with no dishes or crumbs left out overnight
- Store food and pet food in airtight containers
- Keep trash sealed and take it out daily
- Fix leaks and dry the sink before bed, since roaches need water more than food
- Seal pipe penetrations under sinks and behind appliances with copper mesh and caulk
- Add door sweeps and seal gaps around baseboards and outlets
- Inspect grocery bags, deliveries, and used furniture or appliances before bringing them in
- Report compactor-chute and trash-room issues to building management
Your Rights: Landlord and Tenant Responsibilities for Roaches
In many places, owners are legally responsible for keeping multiple-dwelling buildings pest-free, and a roach infestation can count as a housing code violation. Local housing and health rules often require owners to inspect for and remediate pests using Integrated Pest Management.
If your landlord will not act, you can usually file a complaint with your local housing authority, and tenant-protection rules often shield you from retaliation for reporting. Both renters and owners or boards can book us, and we document our work for either side. Check your local rules, and note this is general information, not legal advice.
How Much Does Roach Extermination Cost?
Pricing depends on the size of the unit, how heavy the infestation is, the building type, and whether neighboring units need treatment too. As general guidance:
- Single-apartment treatments: about $150 to $400, with initial visits often $250 to $600
- Follow-up visits: roughly $100 to $300
- Monthly maintenance plans: about $50 to $100 a month
- Building-wide programs for co-ops and condos: starting around $500 and rising with size
Roach Control Across the Areas We Serve and Why Choose Pest Control TC
We treat roaches in older homes, apartments, condos, co-ops, and commercial kitchens. We know how these buildings are put together and where roaches travel between units through shared walls, pipe chases, and outlets.
As a licensed, insured, family-run company with decades of hands-on experience, we lead with IPM and low-spray methods, set honest timelines, and back our work with a re-service guarantee. Book a free estimate and we will lay out a clear plan and timeline.
Our Step-by-Step Approach
- 1
Inspection and Species ID
We inspect kitchens, bathrooms, and harborage points, confirm the exact species, and place sticky monitors to map where roaches travel and breed.
- 2
Targeted Gel Bait
Pea-size gel placements go into cracks, hinges, and crevices. Many small placements beat a few large ones, so roaches keep feeding and carry the bait back to the colony.
- 3
Insect Growth Regulator (IGR)
An IGR stops nymphs from maturing and breeding, which collapses the population instead of just thinning the adults you can see.
- 4
Crack-and-Crevice Dust
Boric acid or a similar dust goes into wall voids, behind outlets, and under appliances where bait alone cannot reach.
- 5
Follow-Up and Monitoring
Return visits 2 to 3 weeks apart kill newly hatched nymphs, and the monitors confirm the colony is gone before we call it done.
Frequently Asked Questions
Most single-apartment treatments run about $150 to $400, with initial visits often $250 to $600 and follow-ups $100 to $300. Monthly maintenance plans are roughly $50 to $100 a month, and building-wide programs for co-ops and condos start around $500 and rise with size. Costs in dense, multi-unit areas can run above national averages because of old wall voids and shared-wall infestations. We give upfront, no-surprise quotes.
Water bug usually means a large American or Oriental cockroach that wanders in from basements, drains, and sewers and does not build colonies indoors. The small, half-inch, light-brown roach with two dark stripes that breeds in your kitchen and bathroom is the German cockroach, the species behind almost all persistent apartment infestations.
Most apartments see major reduction within 7 to 10 days, with full elimination usually in 2 to 4 weeks. German roaches need at least 2 to 3 visits spaced 2 to 3 weeks apart to kill newly hatched nymphs and break the breeding cycle. Heavily infested or shared-wall buildings can take longer.
German roaches travel between units through shared walls, pipe chases, and electrical lines, so a clean apartment can be re-infested from a neighbor, the trash or compactor chute, or an adjacent restaurant. Lasting control often needs building-wide or floor-level treatment, not just one unit. Roaches also ride in on grocery bags, deliveries, and used appliances.
Most building contracts cover a quick baseboard spray, but modern German roaches are widely resistant to those pyrethroid sprays and treat them as a repellent, scattering deeper into walls and into neighboring units. The spray also contaminates and repels gel bait. Real control needs targeted gel baiting, an IGR to stop reproduction, and crack-and-crevice dusting, not perimeter spraying.
No. Total-release foggers leave insecticide on open surfaces where roaches barely go, fail to reach the cracks where they hide, and can scatter the colony deeper into walls. Spraying over gel bait also repels roaches and ruins the bait. Professional gel baiting plus an IGR is far more effective.
Often yes, for a few days. Effective gel bait draws hidden roaches out of cracks and wall voids to feed, so you may notice more activity at first, including sluggish or dying ones. That is a sign the bait is working. Do not spray, do not wipe up the bait, and let the follow-up visits finish the colony.
It is safe when applied correctly, and you usually do not have to leave. We use targeted gel baits and dusts placed inside cracks, crevices, and wall voids out of reach, not broadcast sprays, so you, children, and pets can typically stay home and use treated rooms right away. We tell you which spots to keep clear and avoid wiping.
Food residue, grease, crumbs, pet food left out, standing water and leaks, warmth, and clutter like cardboard and paper bags. In dense, multi-unit buildings, proximity to the trash or compactor chute, a neighboring unit, or a ground-floor restaurant matters as much as cleanliness. German roaches need only tiny amounts of food and water, which is why nightly cleanup and sealing harborage are key.
In many places, yes. Local housing codes commonly require owners to keep multiple-dwelling buildings free of pests, and a roach infestation can be a code violation. Many rules also require owners to inspect for and remediate pests using IPM. If your landlord will not act, you can usually file with your local housing authority, and tenant-protection rules often shield you from retaliation. Check your local rules.
