Carpet Beetle Or The Larvae: Which One Causes The Damage?
Surprisingly, the carpet beetle larvae are actually troublemakers. The Adults do not feed on fabric directly but are responsible for laying eggs that hatch into the larval stage. They lay 50-100 eggs on vulnerable materials, which hatch in a few weeks into the fabric-consuming larvae. The fertile grounds ensure that the offspring will have abundant food on hatching. The length of the larvae is about 1/8 to 1/4 inch and densely covered with hairs.
As they feed on materials, they leave spots and irregular holes and can be mistaken for cloth moths. Amazingly, you cannot find them feeding on synthetic fabrics unless blended with wool or soaked with oil or sweat.
The adults feed on pollen and nectar from flowers of buckwheat, spiraea, and other plants with abundant pollen. Their life span ranges from 9 months to 3 years- it mostly depends on their diet and environmental conditions. Adult carpet beetles can fly, which makes them competent at getting into homes. Since they are overwintering pests, they are used to getting into our houses year after year. They reproduce fast and spread in a house like a wildfire.
This Is How Carpet Beetles Can Harm Your family
The good news is, carpet beetles are non-toxic and do not transmit diseases as mosquitoes do. However, they can be harmful to people with allergies. Their larvae have tiny, hair-like bristles on their skin, which cause allergic reactions when they come into contact with your skin, eyes, airways, or digestive tract. They can leave little red bumps on the skin, which look similar to bedbug bites.
If they are residing in your mattress or other beddings, it may be hard to distinguish the two. Both can live in your beddings as they are attracted by the carbon dioxide you exhale while sleeping. Rashes from bed bugs are, however, from their bites as they feed on blood. Allergic reactions may also cause itchy welts that can get infected if scratching is uncontrolled.
Not to freak you out but the carpet beetles are known to gnaw on human hair. They crawl into beds while the victims are asleep and squat in the scalp. They are also drawn by the scent of essential oils.
Long periods of exposure to the tiny bugs may cause carpet beetle dermatitis, which is characterized by pruritic rashes, itching, and papulovesicular rashes. The larvae usually hide in carpets, clothes, and blankets and get into contact with human skin quite efficiently. The airborne fibers of the insects can also cause eye and respiratory tract irritation. Symptoms of allergic reactions to carpet beetles include a running nose, itchy skin, gastrointestinal issues, hives, and red, itchy, and watery eye
The good news is that the symptoms usually go away once the pesky critters s and their shed skin are eliminated from your home. Interestingly, some people become desensitized with long-time exposure but getting rid of the insects is the best option. Allergic reactions from carpet beetle larvae are more painful and less itchy than bites from other bugs such as bedbugs.
When they infest a house, they leave behind excrement and saliva on unprotected food, which contaminates it and makes it a threat to human health on consumption. When bacteria get into the human body, they may cause diarrhea, vomiting, and other infections.
How To Treat Carpet Beetle Allergies
Carpet beetle allergy treatment depends on how a person is affected. For painful itching, a sting swab will provide relief and also promote healing. For soreness, calamine lotion available at pharmacies will calm and soothe the affected area. Other ointments that you can try out include cortisone and Benadryl cream.

Carpet Beetle Damage On Belongings Or Properties

The most common attacked items include blankets, sweaters, coats, scarves, pillows, rugs, and comforters. They mostly eat the underside of rugs and carpets, and along the edges of folds( hems, collars, and cuffs) of fabrics.

Carpets or other clothes that are not used for a long time are an ideal breeding ground for the tiny bugs, and they lay their eggs on such. Blankets and clothing in use are rarely attacked; the same applies to rugs and carpets that are routinely vacuumed.
