Freezing at higher temperatures is advantageous because the rate of ice formation is slower, allowing the insect time to adjust to the internal changes that result from ice formation. [ 24 ] Most freeze-tolerant species restrict ice formation to extracellular spaces, as intracellular ice formation is usually lethal.
In cold climates, they occur only near human dwellings, because they cannot survive severe cold. However, German cockroaches have been found as inquilines ("tenants") of human buildings as far north as Alert, Nunavut. [10] Similarly, they have been found as far south as southern Patagonia. [11] Though nocturnal, the German cockroach
At least six major areas of cryobiology can be identified: 1) study of cold-adaptation of microorganisms, plants (cold hardiness), and animals, both invertebrates and vertebrates (including hibernation), 2) cryopreservation of cells, tissues, gametes, and embryos of animal and human origin for (medical) purposes of long-term storage by cooling to temperatures below the freezing point of water.
American cockroaches generally live in moist areas but can survive in dry areas if they have access to water. They prefer high temperatures around 29 °C (84 °F) and do not tolerate low temperatures. These cockroaches are common in basements, crawl spaces, cracks and crevices of porches, foundations, and walkways adjacent to buildings.
The county conducts roughly 14,000 inspections a year.

The Japanese cockroach (Periplaneta japonica), also known as the Yamato cockroach, [1] is a cockroach native to Japan, adapted to cooler northern climates. [2] [3] [4] It has a flexible univoltine or semivoltine (one- or two-year) lifecycle, depending on the timing of its hatching, and is unusual in being able to spend two winters as diapause nymphs before reaching maturity.
