What are the distinct features of the Australian carpet beetle? 

Australian carpet beetles are known for their destructive habits, as they can cause a great amount of damage to natural or mixed-fiber carpets. They are also hard to detect, so it is advisable to have a carpet beetle larvae inspection if you think you may have an infestation.

Life Cycle

Australian carpet beetles go through four stages in their life cycle egg, larva, pupa, and adult. The life cycle of a carpet beetle is an important factor in determining how to prevent them.

The eggs are laid on or near the food source, and the larvae hatch and start to feed. They grow and eventually turn into pupae. After a certain amount of time, the pupae will hatch into adults.

Different species of carpet beetles have different life expectancies; the Australian carpet beetle usually only has one generation per year, but other species may have three or four generations per year.

Knowing this information is essential in formulating a plan to prevent carpet beetles from taking up residence in your home.

The adult beetle only lives for about two weeks, which means that the life cycle of this pest is very short. This also means that it is important to take action quickly if you think you have a carpet beetle problem in your home.

What types of damage can carpet beetles cause?

Carpet beetles can infest your property and cause significant damage to your belongings. They are attracted to various materials, including carpets, rugs, furniture, clothing, and food. Once they have infested an area, it cannot be easy to get rid of them.

Insects can cause a lot of damage, and when you see one inside or around your property, the eggs have been laid and are hatching. This will most likely occur on your carpeting, in wardrobes, or inside food storage units.

In addition, the damage caused by carpet beetles may not be immediately noticeable. The larvae often eat small, undetectable amounts of material over time- making the problem worse as it goes untreated.

Moreover, these pests are also known to feed on other insects and dust mites, attracting them to areas that are not well-maintained. Rugs, carpets, furs, museum collections, and taxidermy specimens are commonly attacked by this pest.
