I've got a cactus that's over 20 years old. It's similar to an Opuntia, but I'm not sure of the exact name. Recently, it's been looking pretty sick; it's covered in dead white insects and some black ones that are still alive. The cactus is turning a grayish-green and yellow, with many branches dying and a few young sprouts rotting. I tried replanting some healthy-looking parts, but they just keep dying, even after I cleaned them carefully. I think the roots are okay since it has produced some new sprouts.
I've stirred the soil to help with water absorption, fertilized it, and even added 10 liters of cactus soil to revitalize it. However, I'm worried it's not enough. I'm contemplating using a soapy water spray to eliminate the pests but want to make sure it's a safe option first.
I know I haven't paid enough attention to it in the last couple of years, but this cactus really means a lot to me. It was a gift for my father, who had it in his office before he passed away, and I've put in a lot of effort to care for it. English isn't my first language, so I hope this all makes sense. I truly appreciate any advice!

It sounds like your cactus is dealing with a severe pest problem, likely a scale infestation. Those pesky little insects can really damage a plant if left untreated. I suggest treating it right away; spraying it with insecticidal soap can help eliminate the pests. You could also try gently wiping the insects off with a cotton swab dipped in alcohol. Just be careful not to soak the plant too much, as that can lead to rot. Best of luck, and keep an eye on it! Let us know how it goes!
Yeah, insecticidal soap is a good option! Just make sure to follow the instructions carefully. You might need to reapply a few times to get rid of them all.
