Found about 10 of these guys on the floor near the dog bed. None on the dog, some were dead. Easily visible with the naked eye, medium brown color, and looked like 6 legs with a set of feelers. Teardrop shaped body. Don’t appear to be blood filled. Please help!

Dear Bugging out in Virginia,
This is a Smooth Spider Beetle,
Gibbium aequinoctiale, a common household pest that infests stored foods.  According to BugGuide, they are found:  “Mainly houses, flour mills, occasionally warehouses, hospitals, stores” and they feed upon a “wide variety of dead organic materials; may be a dry stored product pest.”  Do you buy bargain bags of dog food?  Was there a bag of dog food near the dog’s bed?  You may want to check the bag for the source of the infestation.
