Recently during COVID I decided to clean the spare bedroom which house several plants. I noticed that a dracaena had young and old leaves with holes. Same thing, but not severe, with my photos, sansevieria and monstera. Today i went to check and the dracaena has way more holes. Im sure its not sun damage as they are not exposed to direct sunlight. The top part of my dracaena has flowered many times and seems not to be affected with holes yet. All that supports it is the old cane that seems to have decayed. Examining the soil a part of the cane came off. It seems that i have to cut off the top and get rid of the cane, but in doing so, i don't think the cutting will flower as usual. Anyway, i can't find any bug around. Near the holes i found tiny black deposits that i assume are bug poop. Please help me solve this mystery.
I live in Ontario and i made the mistake of puting and outdoor plant in this room for the winter.

I would move them back to the place they were happy. Take a magifier and get a close up and make sure you don't have the start of an infestation. If you see any bug, then spray your plant top and bottom of the leaves with some soap insecticide or neem oil. The bite marks look more like a rodent or something big but I can't be sure. Hopefully after the move the plant will recover.
NOT A EXPERT! Just a grow worm! I never met a plant I didn’t love.✌
Hi Oneeyeluke. Thank you for taking the time to reply. The dracaena and the other plants have been in this spare bedroom for more than 5 years. Last spring i bought a random potted perennial for my patio and i brought it to this bedroom for winter. I know this was not a good idea and maybe a bug wad smuggled in. I doubt mice have been chewing my plants. I have 2 very territorial cats that won't allow other pets around. I am cleaning this room very well. I don't see any bug when inspecting my plants. I suspect that the decaying dracaena cane might be harboring something. Im planning to get rid of it and keep cuttings from it. Im very puzzled about this.
