Stink bug control in Philadelphia targets the brown marmorated stink bug, which seeks winter shelter from September to October. The insects gather on warm, sunny exterior walls and enter gaps near trim and baseboards. They are a nuisance rather than a structural pest. Philadelphia Pest Control serves Philadelphia County and confirms the plan and scope on site.
Stink bugs are a fall problem in most of Philadelphia. As the days shorten and the weather cools, the brown marmorated stink bug leaves its summer feeding places and looks for a sheltered spot to spend the winter. It is drawn to the warm, sunny side of a house, and the insects can gather on siding, window frames and porch columns in large numbers.
The trouble starts when the insects find a way inside. They enter through gaps around window trim, the edges of doors, the seams where siding meets the foundation and the openings around utility lines. Once inside a wall, an attic or a closet, they can stay for months and come out on warm winter days, which is why homeowners in the city often notice them indoors well after the outside activity has ended.
This page explains what stink bug control involves, why the timing of the work matters and what a household can do before the insects move in. Calls to Philadelphia Pest Control are answered 24/7 at (855) 974-4733, and the plan is set on site after the exterior and the gaps have been checked.
Brown marmorated stink bug adults seek winter shelter from September to October, according to Penn State Extension. They gather on warm, sunny exterior walls and then enter gaps near trim and baseboards. The timing is the reason the best work happens before the cold arrives, not after the insects are inside.
The insects are looking for a place to overwinter, and a sheltered wall void or an attic gives them that. Once they find a gap, they can move in quietly and stay until the house warms up in winter. Many homeowners first notice them when the first warm spell of the season brings them out of the wall.
Timing the work matters. A walk around the house in early September gives the technician time to seal the gaps before the insects arrive in numbers. A walk in December is too late to stop the entry, though it can still help with the insects already inside.
Brown marmorated stink bugs are a nuisance rather than a structural pest. They do not eat the wood or the framing of a house, according to Penn State Extension. The main problems are the odor when they are crushed, the number of insects in a room and the concern about entering the living space.
A stink bug on a windowsill is annoying, and a crowd of them can be unsettling. They release a strong odor when disturbed, and crushing one on fabric or a carpet can leave a stain. That is why a technician advises against squashing the insects and suggests a safer removal.
The concern is about the house, not the building's structure. Because the insects do not damage the framing, the plan focuses on keeping them out of the living space, and on the gaps that give them access.
Stink bugs are drawn to warm, sunny surfaces in the autumn, which is why they gather on the southern and western sides of a house. They rest in those spots before moving into gaps. Traps and exterior work are often placed on those walls because the insects collect there in numbers.
A warm wall holds heat through the afternoon, and the insects use it to stay active while they look for shelter. The siding, the window frames and the porch columns on that side are where the gathering is most visible.
A technician can use the gathering to advantage. Traps and exterior treatments placed on the sunny walls intercept the insects before they find a gap, which reduces the number that make it indoors.
Walk the outside of the house in early autumn, check the window trim, door edges and the siding seams, and note any gaps. Keep screens in good repair and close windows on warm afternoons. A short list of gaps helps the technician prioritize the sealing.
A simple walk is the best first step. Look at the joints where the trim meets the siding, the corners of the windows, the gaps around pipes and vents, and the spaces under the eaves. Mark anything that looks open with tape so the technician can find it.
Indoors, check the window frames and the edges of the room for insects during the first warm days of the season. Vacuuming the insects up and emptying the vacuum outside is more effective than squashing them.
Do not crush stink bugs on fabric or a carpet, because the odor can linger and stain. Do not spray insecticide into a wall void or an attic without a plan, and do not use a fogger in a room where people sleep. Keep children and pets away from exterior treatments until the product has dried. Call (855) 974-4733 if the insects are heavy inside the house.
The technician checks the sunny walls, the porch, the window trim and the siding seams before the insects settle in. Gaps around the windows, doors, vents and utility penetrations are noted, because those are the points where the insects enter.
Inside, the attic, closets, the wall edges and the baseboards near windows are checked for signs of stink bugs. Shed skins, dead insects and dark droppings are recorded, since they show where insects have been sheltering.
Gaps around trim, the seams of siding, the edges of door frames and the spaces around pipes and wires are sealed with materials suited to the surface. The work focuses on the openings that lead to wall voids and the attic, rather than every crack on the outside.
Where the plan calls for it, traps are placed on the sunny exterior walls to catch the insects before they enter. A residual treatment may be applied to the exterior surfaces where the insects gather, and the technician explains where it is placed.
Insects that have entered the house are removed by vacuuming or by hand with a plan agreed with the homeowner. The technician then reviews the plan for the next season and notes the gaps that still need work.
The standard service for a house with stink bugs gathering outside. The technician seals the entry gaps, places traps where the insects collect and sets a schedule for the autumn. It is the most effective approach before the insects move indoors.
When stink bugs are already inside, the work focuses on removing them safely and sealing the gaps they used. The technician advises on how to handle the insects so they are not crushed, which can release the odor.
In an attached building the sunny walls often belong to several units. The plan covers the exterior surfaces and entry gaps across the building, and the owner or manager is asked to approve the work on shared areas.

Philadelphia's attached houses have long sunny facades on the street side, and those walls collect stink bugs in the fall. A rowhouse block can look covered in insects on its south-facing front, and the technician checks the gaps along the cornice and the roof edge where the insects enter.
Older Philadelphia houses have wood trim, deep window reveals and mismatched siding added over the decades. Those seams are where stink bugs gain entry, and they are more common on the older houses with lots of trim than on newer, tighter construction.

The cost depends on the number of exterior walls, the size of the gaps and whether the work is done before or after the insects move inside. Philadelphia Pest Control does not publish a figure on this page. A technician confirms the scope and the price on site.
Stink bugs are a nuisance rather than a danger. They can release an unpleasant odor when disturbed, and they are not known to cause harm to people or pets. The main work is keeping them out of the living space and removing them safely.
Stink bugs that enter a wall or an attic in the autumn can stay sheltered until the house warms, and then come out on warm days. Sealing the gaps before the autumn move reduces how many can get in, and the technician checks the interior for insects still sheltering.
Vacuuming is the better choice. Squashing a stink bug can release the odor and leave a stain on fabric or carpet. Empty the vacuum outside and seal the bag or canister, and ask the technician about the safest way to handle a large number.
Early September is a good time to start, before the insects gather in numbers. Booking later can still help with sealing and removal, but the gaps are easier to seal before the insects are inside. A technician will set the timing for the house.
No. Brown marmorated stink bugs are a nuisance rather than a structural pest, according to Penn State Extension. The concern is the insects inside the living space and the odor, not damage to the framing.
