Larder beetles got their centuries ago when they started being spotted inside of larders, the cool food storage rooms used before refrigerators became prevalent. Though larders have long gone out of fashion, these beetles are still a common pest.
Larder beetles are medium-sized at around ¼ of an inch and are of a dark color with a pale band with six spots running down the top of their thorax. They usually have yellowish hairs protruding from their undersides.
Traits & Characteristics
Larder beetles usually enter the home when the weather starts to get colder. Other house conditions can attract them too though. If you have had other pests before (such as rodents or other insects), Larder beetles may scent their carcasses and start infesting your home.
These beetles can be found feeding on fur, feathers, meat, cheese, dry pet foods, and dead insects among other things. Should they find a food source and environment, these beetles could also lay eggs inside of your home. Their larvae are brownish and furry. They can reach ½ an inch in size and usually have two protrusions on their back end. In order to pupate, these larvae burrow small holes in wooden frames or books where they can build their cocoons.
Should you ever have to deal with this pest, you might go through the following scenario: during the previous season you will maybe have had to deal with flies or rodents. If there are cracks and cervices around your home, they might find their way in. In time, you might start to notice small holes in your wood structures and beetles roaming around your house. At this point, the problem should be treated before the insects have a chance to multiply and become a true infestation.
How To Get Rid of Them
If you find yourself with a Larder beetle infestation in your hands, try one of the following treatment options. Firstly, make sure your house is clean and that there are not badly stored foods or animal carcasses lying in dark corners (or even behind walls).
To eliminate the present beetles, use insecticides. Locate the cracks and crevices where they are entering and spray generously. Make sure to open a few windows when doing so to allow the pesticide to ventilate. Remember that you will always have the option of calling a pest control professional. 
In order to avoid the problem entirely, make sure you prevent other pests from infesting your home during other parts of the year. If you have to deal with any other pests during the year, make sure to clean the problem areas thoroughly after dealing with them. If you have a pet, make sure its food is always stored in air-tight containers, as Larder beetles are especially attracted to them.
