[1] The smokybrown cockroach may come indoors during daylight hours to look for food and even to live; generally, however, in warm weather, it will move outdoors.

[2] Often during reproductive periods, females ready for egg dispersal infest homes to protect their offspring and find a convenient place to oviposit.

[5] Females release volatile sex pheromones stimulating the mating behavior of P. fuliginosa males, which receive the chemical signals through sensory receptors located on their antennae.

[7] In addition, the males often participate in perching, whereby their body conformation includes a pointing downward of the head, forelegs extended, as their antennae become aligned 45° from their vertical position.

[8] Whereby, in female mate calling the cockroaches' body is up high, the dorsal end of the abdomen bend towards the ground, and wings are held at a 45° angle.

[9][10] The amount of lipid composition of the cockroach also directly correlates to lower body transpiration, in addition, but provides these species with a more water barrier easing the permeability of the cuticle.

[9][10] Over time even when restricted to certain habitats due to the physiology of their cuticle, they are able to acclimatize through homeostasis seen by decreased salivary gland production.

[10] P. fuliginosa, are able to upkeep homeostasis in fluctuating moisture regions by changing their drinking habits, and the water flow rate of fecal matter, as well as cuticle transpiration.

[11] P. fuliginosa are considered pests in many geographical areas around the world, including the Southern United States and Japan, as they are very effective at invading urban homes, restaurants, hospitals, and many other crowded places.

[13] The use of the densovirus is an interesting technology to use as many methods are ill-equipped to minimize the impacts of the smoky brown cockroach as they can change their sensory behavior to insecticides over time.

[12][13] In a study done, when P. fuliginosa are exposed to the artificially extracted densovirus from a diseased cockroach, high mortality occurred with exposure to low doses.
