Scorpions are arachnids, which means they are related to spiders. They are nocturnal predators that feed on insects and other arthropods. There are 1500 known species of scorpion in world and 70+ species in the U.S., most of which live in the Southwest.
The most dangerous scorpion in Arizona is the bark scorpion (Centruroides sculpturatus). Like all scorpions, it is venomous. A bark scorpion’s sting is painful, and the venom is neurotoxic, which means it attacks the nervous system. Bark scorpions generally hide under tree bark, leaves, and debris. They also like mesquite, cottonwood, and sycamore groves. Bark scorpions are the only scorpions that climb and they are the most likely species to get in houses, especially in newly developed areas.
The roof rat (Rattus rattus) is also known as the ship or black rat. Adults can be six to eight inches long, not counting the tail. It ranges from black to light brown in color. It is destructive, contaminates food, and carries disease. Roof rats are nocturnal and omnivorous.
When outdoors, they prefer to nest in trees or other high places, but sometimes live in burrows in or under vegetation around buildings. They have a stupendous rate of reproduction, producing four to six litters a year, with six to eight young per litter. A roof rat reaches adulthood when it is between two and five months old.
The German Cockroach (Blatella germanica) is the most common cockroach. Not only is it a nuisance, it can spread disease. They are usually found in kitchens or bathrooms, but can be found anywhere people eat or drink. The German cockroach is omnivorous and has been known to eat table scraps, pet food, and even book bindings.
They prefer warm (70° F) and humid places, and they most commonly enter building through paper products or paper packaging, or through second-hand appliances like TV’s or refrigerators. German cockroaches cannot survive away from humans and appear to be vulnerable to cold temperatures the same as termites. one of the most eco friendly and successful ways to get rid of termites is to freeze them. This is a very common method in many companies and is the most preferred by this termite control mesa company!
The wood rat (Neotoma genus) is also known as the pack rat. There are 22 species in North and Central America, seven or eight of which live in North American deserts They are about the size of Norway rats, but have a hairy, rather than naked tail, soft, fine fur, and relatively large ears. They can live in habitats ranging from mountains to deserts. They can also get into buildings near rocky areas.
Wood rats can carry disease, most notably plague. Dead or dying wood rats should therefore not be handled. Wood rats can also be destructive, as they may shred furniture or mattresses for lining nests. They are also thieves and have been known to steal small object like jewelry, can tabs, and eating utensils, especially from campers or backpackers.
