Nobody wants to flip on the kitchen light and see cockroaches scatter. But it happens — even in nice neighborhoods like Johnston. Roaches don’t discriminate based on how clean your home is. They follow moisture, warmth, and food sources. And once they’re established, they multiply fast.
Miller Pest Solutions has been eliminating cockroach infestations across the Des Moines metro since 2001. If you’ve got roaches in your Johnston home, we’ll get rid of them.
Signs of a Roach Infestation
Cockroaches are nocturnal and prefer tight, dark spaces. By the time you see one during the day, the infestation is usually well established. Here’s what to look for:
- Live roaches at night — Turn on lights in your kitchen or bathroom after dark. If roaches scatter, you’ve got an active infestation.
- Droppings — German cockroach droppings look like ground pepper or coffee grounds. You’ll find them in drawers, under sinks, behind appliances, and along baseboards.
- Egg cases (oothecae) — Small, brown, pill-shaped capsules found in hidden areas. Each one contains 30-40 eggs for German cockroaches.
- Musty odor — A large roach population produces a noticeable, oily smell. If your kitchen or bathroom has an unexplained musty scent, roaches could be the cause.
- Smear marks — In areas with moisture, roaches leave dark, irregular smear marks along surfaces they travel frequently.
Why Roaches Show Up in Johnston
The most common roach in Johnston homes is the German cockroach. They don’t come in from the yard — they’re introduced. Grocery bags, cardboard boxes, used furniture, even deliveries from online shopping can carry roaches or their egg cases into your home.
Johnston’s mix of apartments, townhomes, and single-family homes along Merle Hay Road and NW 86th Street means there are plenty of opportunities for roaches to spread between units and buildings. Multi-family housing is especially vulnerable because roaches move through shared walls, plumbing chases, and electrical conduits.
Iowa’s cold winters actually make indoor roach problems worse. German cockroaches can’t survive outside in our climate, so once they’re inside, they stay inside and breed continuously. A single female can produce over 300 offspring in her lifetime.
Our Roach Control Process
Roach control requires precision. Bombing your house with foggers actually makes the problem worse — it scatters roaches into new areas without killing the population. Here’s what actually works:
Assessment: We identify the species and locate the areas of heaviest activity. German cockroaches concentrate near kitchens and bathrooms. American or Oriental cockroaches may indicate a different entry point, like floor drains or sewer lines.
Gel bait application: We apply professional-grade gel baits in cracks, crevices, and harborage areas. Roaches eat the bait and share it with others in the colony through contact and feeding. This creates a chain reaction that collapses the population.
Growth regulators: We use insect growth regulators (IGRs) that prevent immature roaches from reproducing. This breaks the breeding cycle and speeds up elimination.
Sanitation guidance: We’ll give you specific, practical tips on reducing food and moisture sources that sustain the population. Small changes make a big difference.
Follow-up treatments: Roach infestations typically require 2-3 treatments spaced a few weeks apart to fully eliminate. We monitor progress and adjust as needed.
