Wolfie. There's no chance that you will find any species of dermestidae on any kind of fruits. You can find them on flowers,dead animals, in your own house on carpet etc. Never on fruits. So let that be clear to everyone. I don't have a diploma but one of my passions is entomology and macro photography of insect so I think you can trust me in that matter
while back a friend of mine brought his 11 yr old son over to see the bug barn. we talked before hand and he agreed to me trying to pull a fast one on his son.................i reached into the writhing mass of bugs and squished a packet of fake blood, yanked my hand out screaming and shook the blood everywhere..........dam!! that kid exited the barn so fast!!!! lol he was mad at me n his dad for some time, but now stops in and takes care of 'em when i am away. a skull cleaner in the making?? who knows
The Dermestids have been breeding slower then i wanted but still faster then the other beetle colony i have. They are sitting at double the ammount i started with. I started with just some that i found around my home. Now i have 50+ in the colony. The frass builds up fast with 50!
