large orange bugs, help ? insect pro please?

so i was at my grandparents house this weekend, and the house was covered in bugs. while waking up to use the bathroom at 3am, i noticed a fairly large bug on the ground, it was large, round, and BRIGHT orange. i was a bit shocked at first and unable to know what i was exactly looking at. I was scared to kill it due to its size (about the size half my thumb). I picked up the hamper next to it, and it side stepped underneath it swiftly. YES, it literally side stepped while looking at me. I told my parents in the morning and lifted the hamper up only to find it was gone. I have looked for over a hour on google images and orange bugs, ,roaches, slugs, caterpillars, i cant find it. the best thing that i could say it looks like was a habanero pepper. i couldnt see how many legs but i am a bit confused on what it could be. if anyone is a bug expert please help.
