Garden Soon's pest barrier spray program is available in Kennedy Township, Allegheny County at $85–$125 per application. Mid-20th century suburban development on a range of lot sizes. In Kennedy Township, we treat every entry point most homeowners miss — eaves, utility penetrations, and gap-prone spots at the foundation base.
The 90-day residual is the reason quarterly service exists — not to get more visits billed, but because that's genuinely when the protection starts to fade. If we treat in April and you don't do anything again until the following April, you've got six to eight months of the year with no barrier at all, which is exactly the window when ants are most active and most likely to establish indoor trails. The quarterly program keeps residual coverage continuous through the seasons that matter most. That said, some customers with modest pest pressure genuinely do fine with one spring treatment and a fall renewal — we'll say so if that seems like the right fit. As for DIY: the hardware store pyrethroids work on the same chemistry, but the concentrations are lower, the formulations aren't built for outdoor surface adhesion the same way, and most people don't treat the eaves or utility penetrations where the real entry points are. The application pattern matters as much as the product.
For Kennedy Township specifically: ohio River valley influence on lower areas; more exposed conditions on hilltops. First frost mid-October; last frost mid-April. Valley fog affects lower sections. Hilltop areas are windier and can have heavier snowfall.
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.
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 Kennedy Township.
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.
Perimeter barrier spray focuses on the foundation zone and isn't designed as a yard-wide tick treatment. If tick pressure in the yard is the primary concern, a dedicated perimeter or lawn tick spray with targeted application to turf edges, leaf litter, and vegetation borders is a better fit. That said, clearing overgrown vegetation and treating the foundation area does reduce the immediate-zone tick habitat, so there's some overlap on properties with tick issues close to the structure.
Wooded borders consistently mean more pest pressure at the foundation, particularly for spiders, carpenter ants foraging off dead wood at the forest edge, and centipedes — so yes, it affects how much work the barrier spray has to do. For most wooded-border properties in the Pittsburgh suburbs, we'd recommend sticking to the full quarterly program rather than stretching to twice a year, and paying extra attention to the tree line-facing side of the foundation at each visit.
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.
