Signs of Cockroach Infestation
Cockroaches are nocturnal, fast-moving, and expert hiders. By the time you see them during the day, the infestation is already severe. Look for these common warning signs to detect early-stage infestations and prevent a widespread outbreak:
- Droppings and smear marks: Small black or coffee-colored droppings, commonly found in corners, cupboards, drawers, or behind appliances.
- Shed skins and egg cases: Brownish oval shells or fragments hidden in cracks, cardboard boxes, or under furniture.
- Unpleasant oily odor: A strong, musty smell caused by secretions from large cockroach colonies.
Cockroaches hide not only in kitchens or near garbage bins — they thrive in wall cracks, drains, furniture joints, and even inside electronic devices.
Because of their rapid reproduction rate, killing visible roaches or spraying insecticide only provides temporary relief. True cockroach control requires locating and sealing their nesting sites to break the breeding cycle completely.
Johnson Group Cockroach Control Solutions
Johnson Group’s Cockroach Control Service combines two core treatment methods — residual spraying and bait application — using odorless, colorless insecticides that are safe for people and pets.
Our technicians assess the site in detail and determine the most suitable approach, ensuring precise application to target roach breeding and hiding areas while minimizing chemical exposure.
Cockroach Control Methods
Residual Spraying
Residual treatment with low-toxicity, water-based insecticides directly targets roach harborages and breeding zones, especially wall gaps and building perimeters.
For indoor treatment, technicians apply the crack and crevice injection method, treating cabinet undersides, drain outlets, and tight spaces. This ensures effective, long-lasting cockroach control while maintaining safety for children and pets.
Bait Application
Johnson Group applies SafePRO® Cockroach Gel Bait, which attracts roaches to feed and spreads through secondary infection within the colony.
Compared to traditional spraying, roaches develop less resistance to bait formulas. This eco-friendly, odorless, and precise method provides long-lasting results, ideal for kitchens, food areas, and residential environments. Its slow-acting toxin ensures colony-wide elimination without foul odor or chemical residue.

Cockroach Characteristics & Common Species
Cockroaches, also known as blattaria, belong to the phylum Arthropoda, class Insecta, order Blattaria. They have elongated oval bodies with flattened backs and small heads, allowing them to move easily through narrow spaces. They prefer decaying or spoiled food. As one of the most common and undesirable household pests, cockroaches carry numerous pathogens and viruses, posing risks to human health and hygiene.
What Are Cockroaches?
Cockroaches (Order: Blattaria) are flattened, oval-shaped insects that thrive in dark, warm, and humid areas. They feed on decaying organic matter and are major carriers of pathogens, posing serious health and hygiene risks.
Cockroach Life Cycle
Cockroaches go through three life stages: egg, nymph, and adult. They live 6 to 15 months, depending on species and conditions. Females lay egg cases with 10 to 50 eggs in warm, hidden areas and can produce hundreds of offspring yearly. Nymphs hatch, molt several times, then mature into adults that reproduce and continue the cycle.
Common Cockroach Species in Hong Kong
Common cockroach species in Hong Kong include the American cockroach (Periplaneta americana), Australian cockroach (Periplaneta australiasiae), and German cockroach (Blattella germanica). These species thrive in dark, moist environments and pose health risks by contaminating food and surfaces.
