Yes, Garden Soon serves Bellevue for exterior pest barrier spray — $85–$125 per visit for most Allegheny County homes. Compact older borough with late 19th to mid-20th century housing. A properly applied perimeter treatment in Bellevue 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 Bellevue specifically: river valley location moderates temperatures slightly. First frost mid to late October; last frost mid-April. Fog common in the Ohio River valley during shoulder seasons.
Each visit covers the full exterior foundation perimeter — three feet up the wall and three feet out on adjacent soil or mulch — plus all door frames, window frames at ground level, utility penetrations, eaves, and garage door frames. Interior treatment is not included in the standard service and would be a separate add-on for severe indoor activity. Rodent control, bed bug treatment, active wasp nest removal from wall voids, and subterranean termite treatment are not part of this service and require different approaches.
Before we come out, customers usually describe the same few things: ants appearing along the kitchen counter in spring, spiders in the corners of windows, or earwigs showing up in the bathroom after heavy rain. We ask about pets so we can plan dry-time communication, and whether there's anything specific they've noticed — entry points, concentrated activity in one area. On treatment day, we walk the perimeter, apply the product to all the key zones, and typically wrap up within 45 minutes. Pets and kids should stay off exterior surfaces until they're dry — 30 to 60 minutes in normal conditions. In the two to four weeks after the first treatment, some customers notice they're seeing more insects than before, or finding dead ones along the foundation. That's expected and it's a sign the product is working — insects are contacting the treated surface as they move through it. Activity typically drops noticeably after that initial period. We ask customers to give it a full two to three weeks before drawing conclusions, and to let us know if they're still seeing heavy indoor activity after that window, because there may be an entry point we should revisit.
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 Bellevue.
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.
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.
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.
