Critter Problems ~ In Need of A Solution

Problem #1 - Squirrels drinking from the hummingbird feeders.  I have never seen this before.  They climb up the pole and pull the feeder over to them - tipping it so that the sugar water ends up in their mouth.  Now after the hummingbirds have left this fall, I may spike it with a bit of Jack Daniels.  

But now, I do not know what to do.  Need some solution because they seem to be getting a bit chubby from all the sugar water.  

Problem #2 - Deer eating my variegated Liriope Muscari which lines my long driveway - I have lived here for 30+ years, and the plants have been here almost from the beginning.  Never have I had deer eat them; didn't even know they liked them . . .  but this year - there they are up and down my drive, having their dinner or early breakfast or lunch.  All does - I have seen no little ones nor any bucks.   Again, I have no idea what will work to keep them away except if I plant them a crop of hostas somewhere in the back for their salad desires.  Applying something to them may be rather costly since there are so many.  

Any ideas from the Porch Group?

EDITED to ADD my UPDATE on 08/15/2025 - 

Tried the vaseline on the feeder pole - worked great.  Still looking for the slinky - needs some colors to work into the garden.  Both GREAT ideas and easy.

I despise squirrels - 

Deer problem seems to have taken care of itself for the time being - haven’t seen any recently.  Maybe they found something else they liked better than my variegated Liriope Muscari - they are blooming now so maybe the taste changes when that occurs - or more honey bees around could also be the detergent.

I am not sure that I could use the Coyote urine - yuck - how do they harvest it anyway?  Maybe I can just coast out the coyote’s from the woods to do a little deposit - seems to me they would and should help to take care of the deer too.  

Thanks to all for giving me some solutions.
