All of my Colocasia are getting mites!

They have webs appearing and then white crust appears in some areas after a while, I have tried to get rid of the problem but it just keeps returning!

What is a safe and inexpensive way to get rid of them?

so far I have been wiping them down with alchohol and soap.

When I have a mild infestation, I spray down the leaves with water while rubbing gently to wash off all the mites and webs on upper and lower leaf surfaces. This is practical if you are treating a few plants, but if you have large quantities of infested plants, you might need to bring out the "big guns" (chemical pesticides). Mites do not like moisture so if, once you've removed the bulk of the mites, you keep the leaves misted, that should discourage reinfestation. Are your plants in a hot, dry type of environment? If so, that equals prime mite conditions. Rain showers tend to knock mites off the leaves, but this only works well before webbing is evident.

You will have to follow up within a week because the remaining mite eggs will hatch and restart the problem if you don't.

Thanks, I will keep trying.

It is hot, but not too dry.

What i did on my Colocasias worked on my A. X amazonica 'Poly'.

Thanks again!
