How Do bedbugs form on your bed or mattress out of nowhere?
You will know because the bites become inflamed and are swollen. But you will not feel the bed bugs bite you because their saliva has some numbing agent in it. Though bed bugs are usually living close to your bed area and the spots they live typically have reddish brownishing markings from their fecael matter.
Bed bugs are everywhere. There are lots of ways for them to get into your home. One way is through your luggage or on packages as you travel. They can be introduced to your house on wooden furniture, on yours or guests' clothing, or if you wash your linens at a laundry mat someone else's infestation can become your own. A bed bug infestation can be similar to infestations of other insects in that it could result from someone else treating the problem and they just simply crawl in to find a safe haven and a food source.
Thankfully, they are not in my own home. However, my husband travels on business a great deal of time and he has gotten bitten and when he came home, we kept his luggage outside in the cold temperatures to hopefully kill one if it accidentally hitched a ride home with him. Oddly enough, though, it is heat that will kill them. They are next to impossible to get rid of and the like to hide in crevices. They have a mean bite and they come out at night while you are sleeping. If you stay at a hotel, never put your suitcase on the bed, instead put it on a hard surface, such as a table or top of the bureau. Do not lay your coat over top of the bed, hang it up. If you get them, you will have to pay for an exterminator. One of the things they do is heat the room to an extreme temperature in order to kill them. You must take out any plastic items as well as pets and live plants at the time. That's about all I know from my research, but I hope it was helpful.
They don't form out of nowhere. They hitch rides on clothes and skin, anything that comes in contact with other bed bugs or bed bugs eggs. They hide in the daytime inside wood bed frames or bed mattresses. At night, they come out and feed on your blood. They can survive a long time after one feeding. You can tell you have bed bugs when you have sores (like bug bites) on your feet and legs, and you have tiny white shells of dead bed bugs and skin on your bed. They die with extreme heat, like the clothes dryer for sheets and clothes, but if they get in the mattress, it's almost impossible to kill them unless an exterminator comes.
Bed bugs don't fly, so they need to be carried into your home on luggage or on your clothes. They can also spread from one apartment to another. If you carry a pregnant female, she can give birth to up to 500 eggs. When these baby bed bugs (called instars) are born, they will try and find hiding places as close to the human host as possible. As the hiding spaces fill up, they will move on to other areas.
