The black dots that rubbed off was not Blackspot fungus. Do you have a lot of trouble with Blackspot in your area? What state you in?

We have had the extermator three times and used a fogger once, We started with fleas which the extermator got rid of but he doesn't know what the tiny black bugs are. They don't bother my husband but they get on my body,in my bed but they don't fly,you can easily pick them up. They seem dead when I get them off my clothes.Can anyone help me.

Thank you for the sentiment. I'm glad you have some pass alongs from your mama. I do understand how much they mean to you. I read that it was either fly or possibly thrip poop. We are getting the last of the kumquats off the tree tomorrow and I'll be vigilant about harvesting the next round of them a lot quicker. I read that neem, castile soap, and copper are all good along with magnesium for the trees so I will get to work on that. I make the castile soap myself so I won't even have to buy that and I have neem on hand from using it in my doggy shampoo bars and in my balms. Glad I have so many things on hand around here from my business that have shown to be so multipurpose! I even have magnesium that I make mag oil with so I will just have to get some copper and I think I read that they also could be zinc deficient. My daddy hasn't fertilized them in no telling how long so I will get on that as soon as I find out which is the right kind. Can't remember if he said triple 13 or what! It's exciting to learn about growing citrus and I wish I had learned a long time ago. The parents don't really know much about the actual needs of the trees unfortunately. They just planted them and kept them fertilized and pruned. I will be watching some videos to teach myself how to do the pruning of them.

Typically, any tiny flies originating from indoor plants will be fungus gnats, not fruit flies. And they are usually present because the potting soil is excessively moisture retentive, which is the condition they prefer for laying their eggs. And yes, if the infestation is serious enough, the larvae can do damage to plant roots. Generally, a 5-1-1 or gritty mix will not hold excessive moisture and the gnats will not be a problem. Repotting from a peat-based potting mix to one of these will help. As will a thin layer of coarse sand on the top of the soil surface - the adult gnats will not lay their eggs on this material. Watering with a dilute solution of hydrogen peroxide will kill off any existing larvae and the sticky traps are great for collecting adults. Problems with fungus gnats is almost always attributed to a watering issue - either too frequent watering or a soil mix that is not fast draining and/or too water retentive.
