Because you are crazy, go see a shrink
Bed bugs are tiny bugs that can be incredibly hard to see in most cases. Stink bugs are on the larger side, and are generally seen outdoors, unlike bed bugs.
Bed bugs are really tiny but some adults grow to an amazing and gross size of 4-5mm
You can sometimes see them, although they are very small.
It was probably a mosquito bite from the past.
They are nocturnal so people rarely see them.
They do not cause long term damage. However, some people are allergic to them, so bed bugs can be fatal. Bed bugs give humans rashes on their necks and faces. Some people may not see rashes at all.
Bed bugs can be drowned. So you just turn to your bath tub and set the water to a high enough point and lay in there for at least about 10 minutes. Once you get out you will see the bed bugs floating in your tub. If the bed bugs won't drown turn the water higher than the tempature you have been in. You might need to wash your bed or mattress for the bed bugs to get off, only if you don't have bed bugs on you. So make sure you clear yourself off before you soak or drown the bed bugs. Once you are done, you may sleep somewhere that doesn't include the bed bug infestation and you may also sleep on a couch.
Yes, bed bugs can go from one apartment or townhouse to another if they are also not treated in your townhouse. You can take a chance and not treat for them, but usually when a person in apartment or townhouse gets bed bugs, there is a chance that you could end up with those little fellows too. If your neighbor comes to your townhouse, they can have bed bugs on their clothes and leave them behind for you to enjoy. Call a professional to come over to see if you might have them and usually they will treat your townhouse to be cautious, but you will have to pay for this treatment unless you can prove that you don't have them already. Check to see the laws in your area to see who has to pay, some states are different then others.
They can be, and it is very common. You will be able to see signs of bed bugs on the exterior of the mattress as well.
One can message their local pest control company and request them to mail or e-mail you some information and/or pamphlets about bed bugs. These will include a description and some pictures to be able to use as an accurate account for bed bug comparison.
You will feel a bite when you are awake. Bed bugs have a relatively large sucking organ and they do not use a anestethic like mosquitos do. Most bites occur at night, though, when you are asleep.
To determine if you have bed bugs in your home, look for signs such as small red bites on your skin, dark spots on bedding or furniture, and a musty odor. You may also see live bed bugs or their shed skins. If you suspect an infestation, contact a pest control professional for confirmation and treatment.
