Cockroach Control – What You Should Know

Why they appear, what attracts them, and when to take action.

Seeing cockroaches at home is unsettling, but prevention and targeted treatment are possible.

Where Cockroaches Come From

Hitchhiking & Deliveries

Roaches often arrive inside grocery boxes, cardboard, used appliances/furniture, or tenant move-ins.

They slip through gaps around pipes and drains, door thresholds, baseboards, and vents—especially where moisture is present.

What Attracts Them to Homes

Why Cockroaches Are a Concern

Health & allergies

Roach allergens can trigger asthma and allergies—especially in children—and may contaminate food and surfaces.

Rapid breeding & spread

German cockroaches multiply quickly; one hidden ootheca (egg case) can seed a large infestation.

Hard to eliminate with DIY

They hide deep in cracks and can develop resistance; successful control needs the right baits, placements, and follow-up.

Frequently Asked Questions

German cockroaches (small, tan with two dark stripes) are common in kitchens/baths. Larger American/Oriental species often originate from drains or building basements. We identify on inspection.

It’s normal for 3–10 days as activity concentrates at bait points. Avoid cleaning away bait or spraying over it; let it be carried back to nests.

Typically no for bait- and crack/crevice-focused programs. We’ll advise re-entry timing if other methods are required.

Light infestations: noticeable reduction within 1–2 weeks, with follow-up in ~2–4 weeks. Heavy, multi-unit, or cluttered sites may need additional visits and building-wide coordination.

Clear access to sinks, stoves, fridges; bag excess cardboard; empty cabinet bottoms if we’re treating cracks; fix leaks and clean grease.

We pair treatment with sanitation, moisture repair, and sealing. Ongoing monitoring and good habits (especially managing cardboard and night-time food/water access) keep them out.
