Ants finding the one damp spot in a dry summer, a black widow in the window well, mice looking for a way in as it cools, wasps that got aggressive by August. Matched with a licensed applicator across the Wasatch Front.
Most of what ends up inside a house came from outside first. The exterior is where the work starts, not the baseboards.
Five kinds of pest problems that make up most calls here, and the seasonal patterns that drive each of them.
Most calls start as one pest and end up being a perimeter conversation instead. A licensed applicator treating the exterior consistently is what keeps ants, spiders and the rest from making it inside in the first place.

Learn more →A mouse problem is usually an entry-point problem before it is a trapping problem. Voles never come inside at all — the damage shows up in the lawn each spring after a winter of work you never saw.
Learn more →Wasp and hornet colonies get more aggressive as they grow through summer, not less. A licensed applicator has the protective equipment and the experience to take a nest down without turning it into a worse afternoon.
Learn more →Neither box elder bugs nor cluster flies bite or damage a house — they are a nuisance problem, not a danger, and the fix leans heavily on sealing rather than spraying. Timed exterior treatment is what keeps a bad fall from becoming a bad winter indoors.

Which pest, how often, and where in the house or yard — that is what determines who gets matched to the call.
Someone equipped and licensed to apply pesticide in Utah, not a referral desk guessing at your problem.
Where the pest is a recurring seasonal pattern rather than a one-time problem, you will hear about ongoing service rather than getting sold it automatically.
The pattern repeats every year, roughly in this order. Ants start moving toward houses as the ground warms and the yard dries out, chasing whatever moisture your home holds that the landscape no longer does. Wasps build through late spring and get genuinely more aggressive as their colonies peak in the heat of summer. Black widows are active through the warm months but do not disappear in winter — they simply retreat further into the undisturbed, sheltered spots they already favored.
By fall the pattern shifts again. Box elder bugs and cluster flies mass on warm south- and west-facing walls looking for a way to overwinter, mice start testing gaps around the foundation as the nights cool, and voles go to work under the season's first real snow cover, doing damage to lawns and young trees that will not show until it melts. None of this is random. Treatment timed to the calendar, rather than to whichever pest finally got someone's attention, is what actually gets ahead of it.
An exterior treatment breaks down over time — weather, sprinkler overspray, new plant growth, construction debris along the foundation all wear it down faster than most people expect. Quarterly service exists because the pest pressure itself changes every few months along the Wasatch Front, so a treatment timed to spring ants is not doing much by the time fall invaders show up. Matching the visit schedule to the seasonal pattern is the actual logic behind it, not a sales calendar.
That does not make it the right call for every home. A property with no history of recurring problems, reasonably well-sealed, without a lot of landscaping pressed against the foundation, can often do fine on a single seasonal treatment or a one-time call when something specific shows up. Quarterly service earns its cost on a property with a track record — recurring ants, an ongoing spider problem, a yard voles keep coming back to. Ask whoever you get matched with to size the frequency to your actual history rather than default to the biggest package.

Pest 801 does not apply any pesticide ourselves. We are a referral service that matches your call with a licensed pest control company operating in your area. Applying pesticides commercially in Utah requires a state license, and that is not something a referral service can substitute for.
Black widows are genuinely common along the Wasatch Front, particularly in undisturbed spaces like woodpiles, window wells and meter boxes. That does not mean every dark spider in your garage is one, and it does not call for panic — it calls for knowing where they tend to be and having those specific spots addressed. A bite is uncommon but does warrant medical attention if it happens.
Utah's summers are dry, and ants come indoors chasing the moisture your house holds that the yard no longer does. It is less that ants appear out of nowhere and more that your house becomes the most attractive water source around for a stretch of months. Perimeter treatment timed to that pattern, plus fixing any obvious moisture sources, is what keeps it from becoming an annual habit.
It depends on the property and what has been a problem before. Quarterly service makes sense where ants, spiders or seasonal invaders have been a recurring issue and the goal is to stay ahead of them; a single seasonal treatment or a one-time call for an active problem is plenty for plenty of homes. Ask the company you are matched with to size the frequency to your situation rather than sell you the biggest package first.
Mice want inside your house, particularly as it cools off in fall, and show up as droppings, gnaw marks, or noise in walls and attics. Voles never come inside at all — they live outdoors year-round and do their damage to lawns and young trees, most of it hidden under snow cover until it melts. They need different approaches, so if you are seeing signs of both, say so when you call rather than assuming one company automatically covers the other.
