A cockroach infestation is more than just unsettling — it’s a serious sanitation concern.

Cockroaches contaminate food and surfaces, trigger allergies, spread bacteria, and multiply quickly when conditions allow. Because they hide during the day and reproduce rapidly, infestations are often much larger than they first appear.

If you see one cockroach, there are usually many more hiding nearby.

At Avista Pest Control, we focus on identifying the source of the infestation and eliminating it completely — not just treating the visible insects.

What Are Cockroaches?

Cockroaches are resilient insects that thrive anywhere food, moisture, and shelter are available. While more than 4,000 species exist worldwide, only a small number commonly invade homes and commercial buildings.

The most common indoor species include:

  • American cockroach
  • German cockroach
  • Oriental cockroach
  • Brown-banded cockroach
  • Australian cockroach

Cockroaches have flat bodies that allow them to squeeze into tight spaces. They reproduce through egg capsules called oothecae, and populations can grow rapidly in warm, humid environments.

How Do Cockroaches Behave?

Cockroaches are primarily nocturnal. During the day, they hide in:

  • Cracks and crevices
  • Behind appliances
  • Inside cabinets
  • Wall voids
  • Bathrooms and kitchens
  • Electrical devices and cluttered storage areas

If you see cockroaches during the daytime, it may indicate a heavy infestation or overcrowding.

They prefer dark, humid environments and are especially attracted to kitchens, pantries, drains, and trash areas.

What Do Cockroaches Eat?

Cockroaches are scavengers. They feed on:

  • Sugary and starchy foods
  • Meat and grease
  • Crumbs and food residue
  • Cardboard and paper products
  • Pet food
  • Organic debris

They can survive on extremely small food sources, which makes sanitation alone insufficient once an infestation is established.

How Cockroaches Enter Homes

Cockroaches can enter through:

  • Grocery bags and cardboard boxes
  • Used appliances or furniture
  • Plumbing and drain lines
  • Cracks in foundations or walls
  • Gaps around doors and windows

They may also migrate from neighboring units in multi-family housing.

How Do Cockroaches Affect Homes and Humans?

Cockroaches are a public health concern due to the bacteria and allergens they carry.

Contamination

Cockroaches travel through sewers, drains, and garbage before moving across kitchen counters, dishes, and food surfaces. They can transfer bacteria such as Salmonella and E. coli through contact, droppings, and regurgitation.

Allergies & Asthma

Cockroach droppings, saliva, and shed skins are known asthma triggers, especially in children. Infestations can significantly worsen indoor air quality.

Odor

Large infestations produce a strong, musty odor from glandular secretions. This smell can linger in cabinets and food storage areas.

Structural & Material Damage

Cockroaches may damage paper goods, cardboard, fabrics, and even book bindings as they forage.

How Do You Manage and Prevent Cockroach Infestations?

Sanitation is an important first step — but it is rarely enough to eliminate an established infestation.

Reduce Food Sources

  • Store food in sealed containers
  • Clean kitchen surfaces thoroughly
  • Avoid leaving pet food out overnight
  • Empty trash regularly

Reduce Access & Shelter

  • Seal cracks and gaps around doors and windows
  • Repair plumbing leaks
  • Eliminate excess moisture
  • Reduce clutter, especially cardboard storage

Even well-maintained homes can experience cockroach infestations, particularly in multi-unit housing or during seasonal changes.

Avista is here to help!

Effective cockroach control requires:

  • Identifying the species
  • Locating harborages and breeding areas
  • Using targeted treatment strategies
  • Ongoing monitoring when necessary

Simply spraying visible cockroaches will not eliminate the infestation.

At Avista Pest Control, we use professional-grade products and strategic placement techniques designed to eliminate colonies at their source and prevent reinfestation.
