How long does pest control last? Most of the products we use keep working for 30 to 90 days, depending on the product. Most exterior treatments last about 90 days, which lines up with a visit every three months.

That’s why quarterly pest control is the right fit for prevention in most Kansas City homes. Here’s what affects how long a treatment holds up.

How long does pest control last outside?

Most exterior products last about 90 days. Once dry, normal rain won’t wash them away, because much of what we use is microencapsulated.

Microencapsulated products hold the active ingredient in tiny capsules that release over time. If heavy rain hits before the treatment dries, call us and we’ll schedule a free follow-up. Our post on whether rain washes away pest control covers more.

Why does pest control need to be repeated?

Products break down over time, and new pests keep arriving from outside. Regular visits refresh the barrier before it wears thin.

Pests also change with the seasons. Even a good treatment fades, so lasting protection comes down to keeping it refreshed on schedule. Ants surge in late summer, while mice and fall invaders like boxelder bugs and stink bugs push inside when nights turn cold. Each visit is matched to your home’s layout, pests and season.

How long does it take pest control to start working?

Allow 10 to 14 days for products to fully work. Seeing some bugs in that window is normal.

Pests often come out of hiding as they cross the treatment. Our post on more bugs after pest control explains what’s going on.

How often should you get pest control for lasting results?

Quarterly service is the right fit for most homes. If roaches or mice are the main problem, start with monthly or bi-monthly service, then step down to quarterly once they’re under control.

  • Quarterly: $56.50 a month, 4 visits a year.
  • Bi-monthly: $74.50 a month, 6 visits a year.
  • Monthly: $99 a month, 12 visits a year.

Our post on how often roaches and mice need service goes deeper.

What if pests come back before the next visit?

Call us for a free re-service. It’s included on every recurring plan, and we’re usually back the same day or within 48 hours.

Free re-service is limited only by product labels. See our free re-service guarantee for how it works.
