Hi all

Can anyone help? I've had this for around a year and its usually very healthy. It still looks healthy however about a week or so ago I noticed lots of little black dots. They look like soot or dirt but it's not I think they are little bugs? I sprayed it/washed it and also put him in the shower when they werent coming off very easily. Most of them come off after this and I put it back into his place once he had dried off. Well since I've done that there seems to be even more now, please see pics attached.

This was quite expensive and I've looked after it very well so I'm really sad this has happened I dont really want to throw it away, is this fixable? What are these bugs?

Thanks in advance
Jen

I use cold pressed neem mixed with one drop of dish soap with warm water. I apply it on the top and bottom of every leaf on the plant. Besides killing the pests, neem will give the plants a shine and cleaner look. I will repeat if I see anything in 3 days after the first spraying. If you grow indoor plants, neem is a must.
NOT A EXPERT! Just a grow worm! I never met a plant I didn’t love.✌

Welcome! Jen. Your Dieffenbachia has a pretty severe aphid infestation. What did you spray it with other than water?

Hi. Thanks for responding. I sprayed it with water and then wiped down the leaves and stems with dish soap water . I also put it in the shower and hosed it down gently. It got alot of them off but to be honest I easnt sure what they were so I was rather cautious of touching them. Are they harmful to me? How can I get rid of these? Thanks again, jen

Aphids find plants much tastier than you! They are completely harmless to you.

Mix a solution of 5 parts water, 1-part alcohol, and a squirt of liquid dish soap. Then, spray all leaf and stem surfaces until they are dripping wet. It is a very messy task, but unless you get complete coverage and make direct contact even with the ones you cannot see, the survivors will reproduce and the infestation will return. Be sure the solution runs into the crevices where leaf stems attach to the main stems.

Whatever you use to treat the spider mites, you must get complete coverage because if you miss a few of the tiny critters the infestation will return.

Any Isopropyl alcohol available to you is fine.

Make sure you don't spray in direct sunlight. Wipe after you have sprayed thoroughly. It can be returned to its rightful place after the treatment. If you have been thorough, the aphids will not spread to other plants.
