Bed bugs are visible
A lot of people ask us this question. For some reason, it seems that a lot of people believe bed bugs are microscopic. However, they can grow to the size of an apple seed, and can also look like an apple seed. Here are some bed bugs pictures. When fully grown, they are brown, and apple seed shaped. If they have just recently fed, they can be quite large and engorged. However, in their early stages, they are very tiny, and clear if they haven't fed yet, therefore they can be difficult to spot with the human eye. Bed bugs have two primary instincts: they feed and breed. Typically, they will nest close to where you sleep, because they are nocturnal (they sleep during the day, and feed at night). They can hide in your bed, headboard, end tables, pictures, books, linen closets or anywhere within roughly 16 feet of where you sleep. If they are breeding, you will have very small, hard to spot baby bed bugs. a good magnifying glass and flashlight will help see the smaller bed bugs.
Feces on your mattress
Unfortunately, if you have discovered your bed bug infestation based on the dark spots on your mattress, that means you are into a fairly heavy stage of infestation. However, it is important to be able to identify bed bug feces on a mattress. We have found a common pattern of feces spots to be in the corners or folds of a mattress. If you are at a hotel, and want to quickly check for bed bugs, look in the folds or seams of the mattress. Bed bug feces, or the dark black spots as shown in the pictures on this page, are composed of dried blood. Usually, a bed bug will feed, and then go back to their nesting area. This is where you will see the buildup of dark black fecal matter, as they excreet within a couple hours of feeding. You may also find fecal dark blood stains on other materials, such as your wooden headboard, or night stand. These marks will usually be found relatively close to where they nest.
