Garden Soon provides pest barrier spray in Pittsburgh, Allegheny County — $85–$125 per visit for most residential properties. Pittsburgh as a whole encompasses everything from dense urban rowhouse neighborhoods to larger homes in the East End, from post-industrial vacant lots to new high-rise residential. We treat the full foundation perimeter in Pittsburgh on every visit: foundation band, door frames, window frames, eaves, and utility penetrations.
It usually starts with ants in the kitchen sometime in May. Not a few — a trail running from the back of the cabinet to wherever they found something worth traveling for. You wipe them up, spray some store stuff, and they come back in a different spot two days later. For a lot of people, that's when they call us. For others, it's the wolf spiders that show up in the basement every September without fail, or the earwigs turning up in the bathroom in wet weather, or the centipedes that appear on the wall when the nights start cooling off. These aren't emergencies, but they're annoying enough that people stop putting up with them. The common thread is that these insects are coming in from outside — finding gaps around windows, under doors, through utility penetrations — and a properly applied perimeter treatment interrupts that entry cycle before it gets going. That's what we're set up to do.
For Pittsburgh specifically: urban Pittsburgh climate with the strongest heat island effect in the region. First frost late October in the city core; earlier in outlying hillside neighborhoods. Last frost mid-April. The rivers create valley fog and moderate temperatures near river level. Very variable conditions across the city's terrain.
The quarterly program runs four visits per year timed to the seasons: a spring application when ants are most active, a summer renewal through peak activity months, an early fall treatment before insects start pushing toward warm entry points for winter, and a late fall visit to maintain residual heading into the cold months. The spring visit typically involves the heaviest application. Timing each visit to roughly the 90-day residual window is what keeps coverage continuous rather than patchy.
When we pull up, the first thing we do is a quick walk of the foundation perimeter — we're looking at where mulch meets the foundation, any visible entry points, areas where moisture or wood contact might be creating conditions that attract insects. That takes five to ten minutes. Then we mix the product to label rate and load the sprayer. Application starts at the foundation base and works outward: three feet up the wall, three feet out on the soil or mulch, then we move to window frames, door frames, and any visible utility penetrations. We treat the eaves — often overlooked, but spiders build there consistently. Garage door frames get treated top to bottom. The full application typically takes 30 to 45 minutes for an average-sized house. Before we leave, we'll tell you when the surfaces should be dry, remind you to keep pets off the treated areas until then, and let you know what to expect in the first couple weeks. We also note anything we observed — open gaps around pipes, weatherstripping that's failing — that's worth addressing separately.
Per-visit pricing for the quarterly program lands between $85 and $125, with the range reflecting property size — a smaller ranch with a simple foundation footprint costs less than a large two-story with multiple structure attachments and a long garage. Customers who sign up for the quarterly program pay $300 to $450 for the full year of four visits. One-time single treatments outside of a program are available at $110 to $140 per visit. For properties with a significant existing pest issue at the first visit, we sometimes assess a first-time knockdown fee of $50 to $100 on top of the standard rate — that's for situations where we're dealing with an established ant trail or heavy perimeter activity that requires more product and more time to address properly. Interior crack-and-crevice treatment is a separate add-on and is priced based on the scope of indoor activity. Rodent control, termite treatment, and wasp nest removal are separate services not included in barrier spray pricing.

Once the product dries — typically 30 to 60 minutes after application — it's safe for pets and children to return to the treated areas. We use synthetic pyrethroid products standard in professional pest control. We confirm dry time after each visit and note anything specific worth flagging about your property in Pittsburgh.
Visible exterior nests — like paper wasp nests under eaves or on overhangs — can often be addressed at the time of a barrier spray visit, and we'll note those when we see them. Active wasp or hornet nests inside wall voids or structural cavities are a different situation that requires a separate treatment, not a perimeter spray. We'll let you know what we're dealing with when we inspect.
Yes — we don't lock customers into long-term contracts they can't exit. The quarterly program is structured as a seasonal service, and if you decide after the first visit that it's not what you wanted, we can work something out. That said, one visit gives you a few months of residual, and the program is genuinely more cost-effective per visit than one-time pricing.
Perimeter spray can reduce carpenter ant foraging activity coming in from outside, and treating the foundation and eave areas does help. However, if carpenter ants have already established a satellite colony inside a structural void — which is what soffit activity often suggests — the exterior spray alone may not eliminate the indoor colony. We can assess the situation and let you know whether perimeter treatment is enough or whether a targeted void treatment would be more appropriate.
A lot of our pest barrier spray customers have vegetable gardens, and the first thing they ask is whether the spray is safe near their food plants. It's a fair question and we take it seriously. Most of what we use for perimeter barriers is formulated to dry on hard surfaces and stay well away from edible crops — but where exactly the beds are, how close the treatment zone runs, and what's planted matters. Those conversations about garden layout and proximity often turn into broader discussions about what's working in the garden and what isn't.
