Small Brown Bugs in Your House | Identification, and Habitat
There are many types of bug species that commonly invade homes, and some of them are ticks, drugstore beetles, fruit flies, and more. Since these pests are known to cause damage and pose health risks, identifying them is a must so you can apply appropriate steps to get rid of them.
Through accurate identification, you can get rid of these insects below effectively and prevent them from coming back:
Drugstore beetles are wood borer bugs that usually live within stored foods, such as cereals, cookies, bread, and other food items that aren’t stored in secured containers. They’re particularly seen in pantries and kitchens, where spills and crumbs are common.
They’re commonly known as cigarette beetles, resembling anobiid powderpost beetle. In addition, they’re 1/16 – 1/8 inch long, possess a light-brown color, and are oval in shape.
Moreover, they have a hood-like shield known as prothorax, enclosing and concealing their heads when seen from above.
Carpet beetles are typically seen in carpets and around your rug’s edges. They can grow on lint and debris gathering beneath the baseboards and within the ducts and vents.
You can identify the adult carpet beetle with their shiny, black to dark brown bodies and brownish legs. Their lengths range from 1/8 of an inch to 3/16 of an inch.
Meanwhile, larvae can grow up to 5/16 of an inch and possess light brown to black color. They also have smooth, shiny bodies that are hard and short, stiff hairs covering them.
Silverfish live in moist spaces with high humidity and darkness. Additionally, they also prefer places where there are plenty of starches-based materials, like books and boxes. This is why they’re often detected in:
- Living rooms
As the name suggests, silverfish typically appear silver in color due to the shimmery quality of their skin. However, their real color is light grey and blue.
They possess carrot-shaped bodies with three obvious tails on the rear. On top of that, they also have two slender antennas and are wingless.
Typically, weevils feed on plants. But, once they gain access to your home through cracks and holes, they’ll start infesting by contaminating stored foods with their excretion.
They’re often found gathering by the windows. Although some weevil species, like rice weevils, can be seen in kitchen areas due to the foods they can get there, such as cereals, beans, and nuts.
You can distinguish weevils from other small brown bugs with their unusually long, down-curving muzzle. They also possess small, elbowed antennae and are 1/4 of an inch in length.
Cockroaches are pests known to carry various diseases through their excretion. They’re mostly seen in crevices and narrow cracks of your home, where they’re undetected.
You can also find these pests under the sinks, drawers, cabinets, and behind refrigerators due to the moisture in these areas. These pests are nocturnal, so they seek food at night. They prefer sweet, starchy foods, meats, and any crumbs that they can get in your kitchen.
Identifying them is easy with their flattened oval body, bent downward head, and long antennae. Their length can range from 1.4 to 2 inches. Furthermore, they have shimmering brown or black leathery integuments.
Ticks are parasitic pests that lay eggs in several parts of your home, such as the window, baseboards, curtains, and furniture. They have an oval body shape, consisting of the abdomen and cephalothorax.
In addition, they have a ‘false head’ that protrudes forward past their bodies and four pair of legs. Ticks don’t have an antenna and are approximately 3/16 of an inch.
Unfed females and male ticks are reddish-brown. You can distinguish the female from the male by spotting the big, silver-colored area behind their head.
Furthermore, female ticks grow as big as 1/2 of an inch after feeding, comparable to the size of a grape.
Fruit flies are known to breed in trash containers, drains, and empty bottles of sodas. They’re especially drawn to rotting vegetables and ripened fruits in the kitchen.
You can identify them with their feathery bristle antenna, thickened from margin wings, and typically bright red eyes. Their bodies are tan except for their rear part, which is black and can grow up to 1/8 of an inch.
Drain flies typically live in areas where water accumulates, such as rarely used toilet bowls, sinks, floor drains, and drain pans found under the refrigerators.
One can identify drain flies with their tan or light gray bodies and light-colored wings. On top of that, their wings and bodies are covered with long hairs, giving them a hairy, moth-like appearance. These insects can grow up to 1/8 of an inch.
Stinkbugs are pests that prefer to dwell within your walls, crawl space, or attic during winter. They possess solid green color with a yellow-orange rim around their scutellum.
The stinkbugs have black antennae, and their sizes range from 0.5 of an inch to 0.7 of an inch. These insects feed on a variety of food, such as tomatoes, peaches, soybeans, and more.
These insects invade homes in search of a warm place to stay during the winter season.
