Post-Treatment Bug Sightings: What's Really Going On?

Here's what's normal, what's not, and when to call your exterminator back.

So, you booked a professional pest control treatment, and a few days later… bugs. Still crawling, flying, or creeping around like they didn't get the memo. Before you panic (or write an angry review), here's the truth: seeing some pest activity after treatment can be completely normal. But not always.

Let's break down what you need to know about post-treatment pest activity and when it's time to take action.

1. It's Part of the Process (For a Little While)

Professional pest control treatments disrupt pests where they live, feed, and breed. That disruption often flushes them out of their hiding places—so yes, you might actually see more insects for a few days as they evacuate treated nests, wall voids, and other harborage areas. This is especially common with ant treatments and insect control services.

🔹 What's Normal:

  • Increased bug activity for 1–10 days post-treatment
  • Slow-moving, disoriented, or dying pests
  • Insects appearing in new areas as they flee treated zones
  • Temporary increase in activity before complete elimination

🔹 What's Not Normal:

  • Bugs still active and thriving 2+ weeks later
  • No noticeable drop in pest numbers after initial treatment
  • New infestations appearing in previously treated areas
  • Pests showing no signs of distress or mortality

2. The Type of Pest Matters Significantly

Different pests respond to treatments at vastly different rates, and some require specialized approaches that take time to be fully effective.

Fast-Acting Results: Wasp removal and spider control typically show immediate results, with most activity stopping within 24-48 hours.

Slower Elimination: Cockroach control programs, carpenter ant treatments, and bed bug treatments may require multiple visits or specialized protocols—especially if colonies have had time to establish, spread, or reproduce extensively.

Pro tip: If you're still seeing live cockroaches, active ant trails, or bed bug activity two weeks after treatment, it's time to contact us for a follow-up assessment.

3. You Might Be Dealing with a Secondary Infestation

Here's something that catches many homeowners off guard: you thought it was just ants, but suddenly there are silverfish. Or you treated for cockroaches, but now there are carpet beetles. Secondary infestations happen more frequently than you'd expect in Manitoba homes—especially in older buildings, apartment complexes, or multi-family units where pest pressure is constant.

This is exactly why Valkyrie Pest Control's comprehensive inspections cover often-overlooked hotspots throughout your property:

  • Attic spaces and insulation areas
  • Under sinks, appliances, and plumbing fixtures
  • Wall voids and electrical penetrations
  • Foundation cracks and basement areas
  • HVAC systems and ductwork
  • Storage areas and crawl spaces

Our thorough approach is part of what sets our residential services apart from quick-fix solutions.

4. Entry Points Weren't Properly Sealed

Professional pest control eliminates the current invaders—but if the entry points remain open, new pests will happily march right back in. This is where many DIY approaches fall short and why ongoing prevention is crucial.

After treatment, these critical steps are essential:

  • Seal cracks and gaps around windows, doors, and foundations
  • Replace damaged or torn window screens
  • Store all food in airtight, sealed containers
  • Trim vegetation and branches touching exterior walls
  • Address moisture issues that attract pests
  • Install door sweeps and weatherstripping

Don't worry—our exclusion and cleaning services can handle these preventative measures for you, creating a comprehensive barrier against future infestations.

5. The Treatment Didn't Fully Reach the Source

Sometimes treatments don't achieve complete elimination on the first attempt. This can happen when:

  • Previous DIY treatments scattered pests deeper into walls or inaccessible areas
  • The infestation was more extensive or advanced than initial inspections revealed
  • Hidden nests, breeding areas, or satellite colonies were missed during treatment
  • Environmental factors interfered with treatment effectiveness
  • Pest resistance required adjusted treatment protocols

At Valkyrie Pest Control, we don't consider the job done until pests are completely eliminated. We reassess situations, adjust treatment plans, and provide additional services when necessary—because real pest control means total elimination, not just spraying and hoping for the best.
