Cockroaches are one of the most resilient pests we treat. They hide in tight, undisturbed spaces, breed quickly, and often go unnoticed until an infestation is well established. Effective cockroach control isn’t about spraying what you can see; it’s about correctly identifying the species, correcting the moisture and food sources that draw them in, and treating the colony at its source with methods that don’t just scatter roaches into new hiding spots.
At Candor Pest Control, we provide cockroach control for homes and businesses throughout the Treasure Valley, backed by a clear plan and a satisfaction guarantee.

It’s a common misconception that cockroaches only show up in unclean spaces. In reality, they’re drawn to three things: food, moisture, and shelter, and they can thrive on very little of any of them. A small plumbing leak, a pet food bowl left out overnight, or a stack of cardboard in a pantry can be enough to create ideal conditions, regardless of how clean the rest of the home is. Understanding this helps take the embarrassment out of calling for help, and helps us focus treatment on the actual conditions drawing them in rather than just the visible insects.
Correct identification changes the treatment plan, since each species prefers different hiding spots and requires different bait strategy.
Small and fast-breeding, typically found indoors in kitchens, bathrooms, and around appliances and cabinets. This is the species most commonly responsible for indoor infestations.
Larger, reddish-brown roaches that prefer basements, crawl spaces, and utility corridors, often entering through sewer connections or mechanical rooms.
Dark, shiny roaches that favor cool, damp areas like drains, basements, and crawl spaces.
Found in warmer, drier spots than the other three species, often behind appliances, inside electronics, or near picture frames and furniture away from water sources.
In many Treasure Valley homes and businesses, especially older buildings with shared walls or complex plumbing, more than one species can be present at once. Our inspection evaluates droppings, body shape, and activity patterns to determine the right approach for what’s actually in your property.
Cockroaches need three things to establish a colony: food, moisture, and shelter. They enter through utility lines, door gaps, drains, shared walls, and occasionally hitch a ride in on deliveries or secondhand items. Once inside, they settle into cabinet voids, appliance seams, and plumbing penetrations, staying hidden during the day and active at night.
Seasonal shifts play a role here too. Hot, dry Treasure Valley summers can drive cockroaches indoors in search of cooler, more stable conditions, which is why activity often ticks up as the weather turns.
If you’re noticing any of the above, an inspection can confirm the species and the extent of the problem before treatment starts.
Candor Pest Control offers a comprehensive approach to cockroach extermination, ensuring your property is protected from these resilient pests.
We check kitchens, bathrooms, appliance voids, and plumbing areas to identify hotspots, moisture sources, and contributing sanitation issues. In multi-unit properties, we may recommend checking adjacent units, since roaches move through shared walls and plumbing.
Rather than broad sprays that scatter roaches into new hiding spots, we rely on gel bait placed in cracks, hinges, and cabinet gaps, along with crack-and-crevice applications and insect growth regulators (IGRs) that interrupt the breeding cycle. This approach targets the colony rather than just the roaches you can see.
We help seal gaps around doors and utility lines and flag moisture issues, like leaks or condensation, that are creating conditions for roaches to thrive.
We offer follow-up services and maintenance plans to ensure your property remains pest-free year-round.

It's uncommon, but some larger species can bite in rare cases, usually when a heavy infestation limits other food sources. The bigger and more common concerns are bacterial contamination and allergy/asthma triggers from droppings and shed skins.
Some species, including American cockroaches, can fly short distances, though they more commonly run or glide rather than sustain flight. German cockroaches, the most common indoor species, rarely fly at all.
Most infestations start from an outside entry point: gaps around doors, utility line penetrations, drains, or shared walls in multi-unit buildings. They can also hitchhike in on deliveries, secondhand furniture, or bags and boxes.
Food residue, moisture (including minor leaks and condensation), and clutter that provides hiding spots are the three biggest draws. A clean home can still have roaches if there's an unnoticed leak or excess cardboard storage.
German cockroaches respond best to gel bait placed directly in cabinet gaps, hinges, and appliance voids, paired with insect growth regulators to interrupt breeding. Because they reproduce quickly, a follow-up visit is usually part of a complete program.
Yes. We use treatments designed to be safe for families and pets once applied and settled according to label instructions.
Activity often increases slightly for a few days as roaches move through treated areas and encounter bait, then declines steadily over about 7 to 14 days depending on the severity of the infestation.
