In Florida pest identification resources, which species is outdoor-dominant in the south region?

• A. Australian
• B. American
• C. German
• D. Oriental

Answer: (A)

In regions like southern Florida, which species tends to dominate outdoors is best understood by how each pest prefers habitat. The Australian cockroach is well adapted to warm, humid outdoor environments and is commonly found in outdoor microhabitats such as leaf litter, mulch, and sheltered spots around buildings. Because its populations thrive outside and only occasionally invade indoors, it’s described as outdoor-dominant in the south.

By contrast, the German cockroach is infamous as an indoor pest, thriving in kitchens and bathrooms and spreading through structural interiors. The Oriental cockroach prefers damp, cool areas and is not as strongly outdoor-dominant in hot southern climates. The American cockroach is widespread and can be found both outdoors and indoors, but the clear outdoor-dominant pattern in the south aligns best with the Australian cockroach.
