There are about 30 different kinds of tarantulas in the U.S. Most are found in the southern states. The bite of a tarantula is painful but not dangerous. Some species have the ability to shoot hairs as a defense mechanism the hairs can be irritating. Tarantulas build burrows in the ground and then ambush prey. They will feed on any kind of insect or even small rodents.
In Iowa, these are not a realistic pest to have to deal with. If any are found it would be from a released pet or pet shop. Tarantulas are beneficial spiders in areas where they are found. Adults have been reported to live for two years or more

Control of spiders is obtained not only through pest control but also by keeping homes clean of clutter and harbor areas. Cleaning up spider webs and food sources will help keep numbers down. Pest control will only help keep numbers down, not eliminate every spider.
There are several species of bed bugs in the U.S. Florida has a strain called the tropical bed bug. Bat bugs are the same as bed bugs but prefer bats as the main host of feedings. Swallow bugs are usually found in bird nests and around birds. They are slightly smaller and can bits humans. Fumigating attics and wall voids after evicting these animals is an effective way of killing these bugs.
Fall is a time of migration for many bat species in North America, this is also when large numbers of bats may enter buildings and structures. Bats are looking for safe areas to mate and reproduce. The four main species of bats in Iowa are big brown bat, little brown, northern, and eastern bats. The big brown bat will over winter in attics and walls without migrating.
Bats in Iowa Big Brown Bats, Little Brown Bats, Red Bats, Northern Long Eared Bats, Hoary Bats, Evening Bat, Silver Haired Bat, and Eastern Pipistrelle. Some bats can carry rabies. The state of Illinois has marked an increase in rabies in the last few years (see news blogs). However, rabies should not be a concern of homeowns. Histoplasmosis is another health factor associated with bats. If bats establish a colony in attics or walls excess droppings can contain this spore. Cleaning these droppings and making the spores airborne can cause some respiratory problems. Respirators should be worn at all times when cleaning bat droppings.
Stored Product Pests
These pests can be responsible for damaging up to %10 of the worlds grain and crops every year. There are numerous types of these pests but most are a type of beetle.
Not much is know about this creature. It is not a spider but considered an arthropod or solupugid. They can and do bite and can create quite a medical problem. They only live in arid areas and stay in burrows in the sand. Camel spiders prey on insects and other smaller creatures like mice. They are also prey of birds, reptiles and even humans. Camel spiders are considered beneficial but are pests when they invade human homes. People in Iowa don’t need to worry about these creatures.
Brown Recluse Spiders
Brown Recluse spiders are also called fiddle backs. They get the name from their reclusive behavior and fiddle shaped design on their back. Adults are generally about the size of a quarter. They have long legs and hold themselves up high off the ground. Brown recluses are light brown in color. They do not make webs but prefer dark, moist, undisturbed areas like crawlspaces, attics and closets. If provoked, they will bite and it can be painful.
There is no cure for infected areas other than removing skin and areas that are dying. If left alone, infected areas spread all over. Medical attention should be sought if bites are suspected. Outdoors they prefer shingles, unused boxes, woodpiles, or clutter in garages for shelter. Pest control is recommended for houses with these spiders.
Weevils are also located all over the U.S. and are usually about 1/8-11mm long. Generally black in color they mainly feed on plants and can invade structures when food sources are no longer available. Removal of plant debris and decaying vegetation is one of the only ways to control weevils. They are harmless to humans other than being an annoyance.
Thrips are very small about 1/64 of an inch in length and black colored. Thrips are found all over the U.S. and can actually bite people. They generally congregate in gardens and around flowers but can invade homes. Thrips can also transfer diseases in plants and flowers destroying them. Several applications of pesticides can be necessary to control thrips where they are prevalent
