Bed bugs can quickly spread through your rental if you don’t know what to look for. Because bed bugs are only about the size of an apple seed and their bites can be mistaken for the bites of a mosquito or a spider, “Do I have bed bugs?,” is a commonly asked question. Here are five signs you may have a bed bug problem.

5 Signs of Bed Bugs in Your Rental

Despite their small size, bed bugs do leave behind some distinct signs that they have made a home in your property.

Some of these signs are more obvious than others, but they are all helpful in identifying the little pests. You should look for these signs in your actual property and on your actual person.

1. Live Bed Bugs:

The most obvious sign that you have a problem is spotting an actual bed bug. These insects are not very large. There eggs measure less than 0.1 inches and full size bed bugs come in at under 0.2 inches.

They have six legs and are oval in shape and rather flat, unless they have just eaten, in which case they will become engorged. They range in color from a deep reddish to a brown.

2. Bed Bug Casings:

Another sign that you have a problem with bed bugs is that you discover bed bug casings. These are the shells that the bed bugs shed when they are going through their life cycle, from nymph to adult.

Bed bugs go through five life cycles and will shed their casing at the end of each cycle. The casing will be reddish or brown in color, will be hollow and the size will vary based on the age of the bed bug.

 The larger the size, the older the bed bug. 

3. Bed Bug Droppings:

A third sign of a bed bug infestation is seeing bed bug droppings. Bed bug droppings will look like little black pen marks. The bed bugs will release these droppings after feeding. They are easiest to see on cloth, such as on bedding or mattresses.


4. Reddish/Brown Stains:

Another sign you may notice, are reddish or brown stains on fabric. This is basically dried blood where the bed bugs have been crushed.

5. Bed Bug Bites:

A final way you can tell if you have bed bugs is, you have bites. This can be difficult because bed bug bites resemble bites of other insects, such as mosquitoes and spiders. In addition, some people have no reaction when they are bitten by a bed bug or it looks more like a rash than a bite.

A typical bed bug bite will appear as an itchy red welt on your body. These bites will often occur on your upper body, usually on your arms and shoulders. The bites are often in a straight line.

Where to Look for Bed Bugs

Bed bugs love to hide in cracks and crevices, so you must examine every square inch of the object when looking for an infestation. When examining any of these pieces, you should look underneath the piece. Check in any seams or other folds.

Search for bed bugs in any holes that may exist in the piece. You can use a credit card and glide it along seams to help unearth the presence of bed bugs or bed bug casings.
