Katchy from Amazon - I have had mine since October 2021. This was my first time changing the sticky pad. I have 2. I keep one in my kitchen window, over my sink. The other lives on one of the plant stands. The one the houses the plant kids that drink the most. This pad is from the unit that is on the shelf of the plant stand. The unit was dusty also so I wiped it down with a damp cloth. I am gonna go a little bit more in-depth with a toothbrush to brush the dust away where the fan blows. I checked the kitchen unit and it wasnโ€™t quite ready for a change yet. I hope this helps someone. I love mine! I also included a bonus picture of my #LadyOfTheNight that I am obsessed with! #StartedFromACuttingNowWereHere
