Yes, Garden Soon serves Dormont for exterior pest barrier spray — $85–$125 per visit for most Allegheny County homes. Dense 1920s-1940s era brick and frame construction on small lots. A properly applied perimeter treatment in Dormont intercepts the seasonal entry cycle before ants and spiders establish trails inside.
When we come out, we spray a liquid pyrethroid — typically bifenthrin or cypermethrin — along the exterior foundation: three feet up the wall and three feet out onto the adjacent soil or mulch. We also treat around every door frame, every window frame at ground level, utility penetrations where pipes and wires enter the building, eaves where spiders like to set up, and garage door frames. The product bonds to the surfaces it contacts and stays active for roughly 90 days on surfaces that aren't getting direct sun and rain exposure. Insects walking across the treated zone pick it up and it works from there. The whole application takes 30 to 45 minutes depending on the property. We ask that pets and kids stay off the treated surfaces until they're dry — usually 30 to 60 minutes. One honest note: this is an exterior perimeter treatment. It does not address mice, bed bugs, active wasp nests inside wall voids, or subterranean termites. Those require different approaches entirely, and we'll tell you that plainly rather than upsell you something that won't work.
For Dormont specifically: south Hills suburban climate. Inner-ring position reduces temperature extremes compared to more rural South Hills communities. First frost mid to late October; last frost mid-April. Urban heat island is mild relative to city neighborhoods.
We use synthetic pyrethroid-based products — bifenthrin or cypermethrin — which are standard in professional perimeter pest control. Once dry, the treated surfaces are safe for pets and children; dry time is typically 30 to 60 minutes under normal conditions. Before we arrive, no special preparation is needed. We ask that you keep pets indoors or away from the foundation area until surfaces are fully dry, and that you let us know if rain is expected — we won't apply if rain is coming within four to six hours of the scheduled visit.
Over the course of a full year on the quarterly program, the spring visit does the heaviest lifting. Ants are breaking dormancy and actively scouting entry points, so the April or May application is the most critical one we do. We apply at full rate and pay extra attention to the spots where ants consistently enter — garage frames, back door thresholds, wherever mulch is piled against the foundation. The summer visit, typically in July, renews residual coverage through the peak activity months and catches spider populations before they build up too much heading into fall. The early fall visit in September or October matters more than people expect — ants start looking for warm entry points to overwinter as temperatures drop, and this treatment intercepts that push before they find their way in. The late fall or winter visit, when it's included, is lighter work since insect activity is minimal, but maintaining even a reduced residual means we're not starting from zero in spring. The program is designed to stay ahead of the seasonal curve rather than react after pressure builds.
A single visit runs $85 to $125 depending on property size. The quarterly program — four visits per year — runs $300 to $450 annually. One-time treatments without a quarterly commitment are available at $110 to $140 per visit.

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 Dormont.
Barrier spray does not address mice or other rodents, bed bugs, active wasp or hornet nests inside wall voids, or subterranean termites — those require different treatments and in some cases different contractors. We'd rather be clear about what perimeter spray handles and what it doesn't than have you spend money on the wrong service.
No — we work on the exterior only, so there's no need for you to be home during the visit. We do ask that any pets are kept away from the foundation perimeter until surfaces dry, so it helps if someone is available to manage that, or if you let us know beforehand so we can coordinate timing.
We won't apply if rain is expected within four to six hours of the visit, because the product needs time to bond to the treated surface before getting wet. If rain moves in after that window, the product will have already set and the application will still be effective. We reschedule around rain events rather than applying in conditions that would wash the product off before it can do anything.
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.
