Are They Dangerous?

Bed bugs are signs of fear; even though they feed on blood, they have no connection with disease. The reason is that they only nest close to one person and do not flutter from human to human as mosquitos do. These bugs hide in the daytime and come out to feed at night so that you will see the spots in the morning.

People are mainly psychologically disturbed as they find bud bugs bite spots on their bodies when they wake up in the morning. However, they can be quite frightening even there is no proof of diseases coming from bud bugs. When talking about carpet beetles, it comes to your health; they are not dangerous.

Bed bugs want to have human blood and prefer to damage carpets, wool, and other material of this kind. They are not living in beds or gather around individuals; you could not see the bite marks from them. When it comes to carpet beetles, you only need to worry about your carpet because they will damage it.

 Skin Reaction

Carpet beetles only break down your furniture, carpets, and all other belongings. On the other hand, bed bugs will attack your skin and health. Both bugs leave evidence of their presence on your skin but in different ways.

Bed Bug Bites

If you have bed bugs in your home, you will feel actual bites on your skin. While you sleep, they will use their saliva to feed on you, or you can say during your sleep, they suck your blood.

In some people, this may lead to an allergic reaction. You will see their bite marks in rows of three on your body. Observe the triangular pattern on your body to differentiate it from the carpet battle.

Many bed bugs feed on one person at a time; you can observe it from the skin rashes. You are dealing with actual bites, unlike the carpet beetles, so that the bed bugs do feed on human blood.

You will need to try some remedies to get relieved from itchings, such as oatmeal baths, cold compresses, or pastes made with baking soda and water. You may need to attempt antihistamines to combat the itching that goes with actual bites.

However, it proved that these bites are not harmful, and you can cure them entirely within days.

Carpet Beetle Bites

Carpet beetles may leave red spots on your body, although these are not bites. These rashes may cause an allergic reaction to the hairs on carpet beetles and traces of their blood. As you observe itching on your skin, you can conclude it’s the allergic reaction due to bed bug bites.

There is a chance you don’t see a skin reaction instantly after carpet beetles invade your home. They do not depend on human blood and might fly under the radar on the contrary.

The hypersensitive response is always the reaction of any bed bug attack, so when you begin seeing skin irritation, the infestation has most likely grown large by then. You may also feel irritation in the eyes and the respiratory tract after some time.

Many individuals get confused with bumps, whether they are the result of carpet beetles or bed bugs. The rashes are the symptoms of bed bugs bites. You may not observe the same triangular pattern with carpet beetles that you see with bed bugs.

That’s why it is essential to know the difference between both bugs in your home.

Where to Find Them?

The reason for having bed bugs in your home is not poor hygiene or dirt. You can find them in neat and clean places too.

They can quickly transfer from one place to another. They may hide in your laundry, luggage, boxes, shoes, and other items brought in from an infested area. When they enter your home, they try to stay close to you, hiding in small cracks and gaps.

Most commonly, they are present in bed parts like mattresses, springs, and folded areas. They travel very fast; bed bugs can be found in every country globally, mostly found in the 50 US states.

Places such as hotels and apartments are the best locations for bed bugs infestation because it is the most common source from which they spread all around quickly. Bed bugs may stick to you and your pets because of the warmth and carbon dioxide you breathe out.

They tend to stay close within 8 feet from their hosts. Similarly, it is not necessary that carpet beetles grow up in a dirty room they also brought in from outside your home. Most of them live and grow up outside your home, maybe hidden in flowers and plants.

Once your house becomes infested with adult carpet beetles, they come inside your home along with the flowers and plants and start laying eggs on the potential food source.

Additionally, tight spaces and cracks around your windows, doors, vents present a suitable access point for them as well.

As Carpet beetle names,  they are not only found in carpets. They also can grow in your furniture and hide in your floors, attic, walls, basements, chimney, and other crawl spaces. They like to live in a place where other pests previously lived in and an indoor plant that has access to sunlight.

They need to stay close to you and come out at night to feed while hiding in the day time. A female bed bug may lay 1 to 12 eggs a day, which adds up to between 200 to 500 eggs for a lifetime.

After hatching, a young bed bug goes through 5 nymphs stages until they reach adulthood. In this whole procedure, they become darker and larger until they reach maturity in two months.
