Life Cycle of Shiny spider beetle
Egg The shiny spider beetle's life begins as an egg, which is usually laid in a protected environment. The egg is small and typically not noticeable to the naked eye. During this stage, the embryo develops inside the egg.
Larva Upon hatching, the larva of shiny spider beetle is worm-like, lacking wings and adult body segmentation. It is focused on feeding and growth, which includes multiple molts where it sheds its exoskeleton.
Pupal The shiny spider beetle then enters the pupal stage, ceasing to feed and often becoming immobile. It undergoes a remarkable transformation, reshaping its body and internal structures into an adult form.
Adult Emerging from the pupa, the adult shiny spider beetle's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

Habitat Preferences of Shiny spider beetle Through Different Life Stages
The eggs of shiny spider beetle are typically laid in dark, undisturbed areas within wooden structures or amongst detritus where larvae have abundant food sources. Larval stages of shiny spider beetle are mostly found in crevices of hardwood floors, furniture, or within old books and papers, consuming organic material. To locate these larvae, one would search in similar indoor environments, especially where old or moldy paper is accumulated. Pupal stages are often in close proximity to larval feeding sites to ensure adequate food supply upon emergence. Adults of shiny spider beetle, once emerged, can sometimes be found near windows or light sources as they are drawn to light. The search for adult shiny spider beetle should include such areas in buildings, particularly in attics or basements with old wooden infrastructures.

What is the most effective prevention against Shiny spider beetle?

Cut off the inward passage. Thanks to the shiny spider beetle's tiny size, insects can come indoors through any cracks or seams. Make it a habit to close doors and windows as you come and go, and promptly repair and seal any cracks on the surface of your house.
Seal all solid food. Keep all dried food in sealed containers to prevent storage pests from entering and infesting the food. Containers can also confine pests that are already in the food and stop them from spreading further.

How to get rid of Shiny spider beetle?

It's crucial to find shiny spider beetle hiding places. Once found, a full-scale, thorough cleaning of the indoor space is a key step to eliminating the shiny spider beetles.
Dispose of pest-infested storage food. Once the food is infested, do not hesitate to seal and dispose of it. Please note that the sooner pest-infested food is removed from home, the better.
Image
Thoroughly clean the food pantry.
There are likely many plastic or glass food storage containers in the pantry. Keeping them clean is a key method for preventing a shiny spider beetle infestation.
Wipe and clean the food pantry with soap and hot water, or with vinegar and mint oil. Make sure to clean thoroughly, paying attention to the corners and lower surfaces of the cabinets, walls, floors, and other storage shelves.
Use a vacuum cleaner. A vacuum cleaner can effectively remove the pests and eggs, which are easy to miss.
Image
Improve storage conditions. Reducing humidity and keeping inventory dry can effectively prevent the breeding of multiple storage pests. Check containers and the pantry for storage pests often and make sure they are sealed.
Set up glue traps. Purchase traps from stores to capture multiple storage pests.
Image
Apply pesticides. Buy pesticide spray at a local store and apply it along the baseboard, under water sinks, or in any cracks and seams where a shiny spider beetle might hide. Be careful not to spray pesticides directly onto carpet, clothes, or furniture.
Hire pest control services. If a shiny spider beetle infestation has become so serious that normal life is disturbed, hire a professional pest control service company for a fully customized pest control operation.
