Scale control

You need to be very careful putting vinegar and salt water on any plant...as you read in Doug's weed control posts...it will burn foliage and can kill weeds ...or your favorite plants. I can not recommend it for scale control even tho it may have worked on your jade plant.
Tried this

Thank you for the pictures. Now I know their names. I used vinegar, salt and water solution to spray on my jade plants. I had my jade plants inside the house. I used three treatments three days apart . I also wipe the solution off and let the jade plants to get a couple hours of direct sunlight.
Hope your plants are okay. :)

Cottony cushion scale

Sorry you lost your lilac, they are so fragrant and special. The critter you have is a scale insect called the cottony cushion scale.
It is quite famous for being the first and best success story for biological control. When the scale was found destroying citrus in CA (brought in from Australia in late 1880's) folks went back to Australia to find something to control it...that is when the vedalia lady beetle was brought in and did a super job of controlling the scale on citrus.
Here is a thorough discussion of what UC Davis says about the pest and how to control it.

Good luck!

Thank you for your kind words.
