Garden Soon provides pest barrier spray in Mount Lebanon, Allegheny County — $85–$125 per visit for most residential properties. Predominantly post-WWII brick and frame construction with medium to large lots. We treat the full foundation perimeter in Mount Lebanon 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 Mount Lebanon specifically: standard Western PA climate. First frost mid-October; last frost mid-April. The South Hills valley can collect cold air and occasional fog in shoulder seasons. Mount Lebanon's elevation moderates extreme temperatures slightly.
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 Mount Lebanon.
The barrier spray is most effective against ants — including odorous house ants, pavement ants, and carpenter ants foraging from outside — along with spiders, earwigs, centipedes, millipedes, and other occasional invaders that enter from the exterior. These are the insects most likely to make their way inside through foundation gaps and entry points, and the perimeter treatment intercepts them in transit.
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.
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.
