Quarterly pest plan or one-time treatment?
One problem or the same problems every year? That question decides most of it. Here's how to choose between a plan and a single visit.

Short answer
A one-time treatment fits a single flare-up, a move-in or a home going on the market. A quarterly plan fits homes that see the same pests every year, because it times a visit to each season: ants and swarmers in spring, nests in summer, spiders, boxelder bugs and mice in fall, rodents in winter. Plans cost less per visit and keep protection from lapsing.
What each option is
A one-time treatment is a single visit: an inspection, treatment inside and out where needed, and advice. A quarterly plan is four visits a year, each aimed at what's active that season, with the outside barrier refreshed every time.
When one visit is enough
One visit makes sense when the problem is new and specific: a spring ant trail, a spider-filled basement in a house that sat empty, or a move-in before the furniture arrives.
- A single flare-up
- Move-in or pre-listing treatment
- No history of repeat problems
When a plan pays off
A plan makes sense when the same pests show up every year: boxelder bugs every September, mice every fall, ants every spring. Residual treatments fade with sun, sprinklers and snowmelt, so one big spray in spring is mostly gone by fall.
What a plan year looks like
Spring sets the barrier and deals with ants and termite swarmer questions. Summer targets nests and stinging insects. Fall is the big one for Salt Lake homes: spiders, boxelder bugs and rodent entry points. Winter is a rodent check of garages, attics and crawlspaces.
Salt Lake's pest calendar is what makes plans useful here. USU Extension says hobo spiders turn up in Utah homes from August through October, boxelder bugs gather on sun-heated south walls in August and September before pushing indoors, and Salt Lake City's average first freeze arrives around October 20, which is when mice push inside. A plan puts a technician at your house just ahead of each of those shifts instead of after them.
Questions to ask
Before signing up, ask what's included, whether the first visit costs more, what happens if pests show up between visits, which pests are covered and how cancellation works.
Sources
Published figures put a quarterly visit at about $100 to $200, with a monthly visit about $40 to $70.
A general exterminator visit typically runs about $100 to $260.
Yes, at any time.
Call; the next visit can be moved up or one added, depending on the plan.
Usually not. Those are separate treatments.
Rarely. Monthly suits restaurants and apartment buildings more than houses.
