Treatments and safety
How do you protect children and pets during a treatment?
Professional pesticides are registered by the EPA, and each label sets how the product must be used, including when people and pets can return. The technician uses every product according to its label and explains the precautions for your household before leaving, such as keeping pets off a treated area until it is dry.
Should I clean before or after a pest treatment?
Before a visit, clear clutter from under sinks and along baseboards so the technician can reach problem areas. After, avoid wiping treated edges for as long as the technician recommends, since cleaning can remove product. Ordinary cleaning of counters and dishes is fine, and keeping food sealed helps every treatment work.
Why am I seeing more roaches right after a treatment?
It is common to see more activity for a week or two. Some products flush roaches from hiding or act slowly, so they wander into the open before dying. If activity has not dropped after about two weeks, call, since German roaches in older kitchens often need a follow-up visit.
What is integrated pest management?
Integrated pest management is an approach, promoted by the EPA, that combines inspection, identification, removing food, water and shelter, sealing entry points and targeted treatments. Instead of spraying on a schedule regardless, products go where pests actually live. It tends to mean fewer applications and longer-lasting results.
Is it safe to knock down a wasp nest myself?
It is risky. Yellowjackets and some wasps defend a nest aggressively, wall and ground nests can hold large numbers of insects, and a ladder plus a swarm is a bad mix. Never seal a nest inside a wall. Call for wasp and hornet nest removal, especially if anyone is allergic.
Pricing and plans
How much does pest control cost in Baltimore?
It depends on the pest, the size of the building, how many units are attached and how many visits the job takes. We do not print dollar ranges here because we have no sourced local figures. The technician gives you the actual price after the inspection, before any work. The pricing page explains what moves the number.
Will I know the price before the technician starts?
Yes. The price is confirmed with you before any work starts, and you can say no. If the plan changes partway, for example when a cellar inspection finds more than expected, the technician explains the change and the price before going on.
Why does bed bug treatment cost more than other pest work?
Bed bugs hide in mattress seams, furniture joints, outlets and baseboards, so treatment is slow, detailed work in every affected room, often with a follow-up. Whether heat or conventional treatment is used also changes the cost. See bed bug treatment for how each method works.
Is rodent control a one-time job or a recurring plan?
Usually a job: inspect, trap or bait, then seal the gaps. Sealing is what keeps rats and mice out, so a quote that skips it is only half the work. Some properties, especially food businesses and buildings next to alleys, add periodic checks. The technician explains both options and their prices.
Does a monthly or quarterly plan make sense for an older house?
It can, when pests return with the seasons or when the house is part of a block with shared walls. For a single problem, such as one wasp nest, a one-time visit may be enough. Ask what a plan includes, what it excludes and what a repeat call between visits costs.
Scheduling and service area
How do I book a non-urgent pest control visit?
Call during the day or send the form on the contact page with your address, the pest you are seeing and when we can reach you. A seasonal plan or a termite inspection can be booked this way. For rodents in the living space, wasps near a door or anything urgent, calling is faster.
What counts as a pest emergency?
Call right away for a wasp or yellowjacket nest by a doorway, rodents loose in the living space or chewing wires, or roaches showing up in a restaurant kitchen. Phones are answered 24/7. If someone has a severe reaction to a sting, call 911 first.
Do you cover my ZIP code?
We cover ZIP codes across Baltimore City, Baltimore County and northern Anne Arundel County, from 21201 downtown to places like Towson and Glen Burnie. Use the ZIP code checker or browse the service areas page. If yours is missing, call anyway and we will say honestly whether a technician can reach you.
Does someone need to be home during the service?
For an interior treatment or a first visit, usually yes: an adult should show the technician the problem areas and confirm the price. For exterior-only work you may not need to be home, as long as gates are unlocked and pets are inside. In a rental, the technician will ask how to arrange access.
Do you service rental homes and buildings I manage?
Yes. Landlords and property managers can book visits for occupied or vacant units, and access can be coordinated with the tenant. For bed bugs or German roaches, tenant preparation makes a big difference to results. See rental property pest control.
Baltimore pests and weather
Why are there so many rats in Baltimore alleys?
Norway rats thrive where food, water and cover meet: open trash, damp ground, gaps under fences and old buildings. Rear alleys behind attached houses offer all four. In 2015 the city reported its Rat Rubout crew planned to treat every alley on a 20-day cycle. The rats in Baltimore alleys guide has more.
Are bed bugs really worse in Baltimore?
Orkin's 2025 list ranked the Baltimore area No. 11, based on its own treatment data from May 2024 to May 2025. That counts one company's treatments, not infested homes, so treat it as a signal. Dense rentals and shared walls can make bed bugs harder to contain. See bed bugs in Baltimore rentals.
When do termites swarm in Baltimore?
Eastern subterranean termites often swarm in spring, on warm and damp days, though timing varies from year to year. Swarmers indoors suggest a colony is near. Carpenter ants can look similar to the untrained eye, so save a few in a sealed bag. Read the termite swarm guide.
Why do stink bugs and mice show up in fall?
As nights cool, brown marmorated stink bugs gather on sunny walls looking for places to overwinter, and mice and rats start moving into walls and cellars. Sealing gaps around windows, pipes and rooflines before the cold helps with both. See stink bugs and fall invaders.
When is mosquito season in Baltimore?
Mosquito activity typically starts in spring and builds through the hot, humid summer, with Asian tiger mosquitoes breeding in small containers and clogged gutters, and marsh mosquitoes near tidal water. Mosquito-borne illness such as West Nile virus exists in the region, so dump standing water weekly. See mosquito control.
