I’ve done a ton of interceptor treatments over the past 18 years. Most recently I had black bugs experimented over the course of roughly 18 months. Finally beating them doing follow up treatments,but I’ve tested concentrations of interceptor ranging 3-9x what the standard dosage (red bugs) at durations ranging 18-48 hours. All treating the whole tank finally having success 3 total treatments 7 days apart back to back. Interceptor is really safe if you administered correctly especially the initial/first treatment on the system. Even at the the insane dosages I’ve never had any loses or really even any issues. If you have a question or anything PM me I don’t mind glad to help.
I dipped all my stuff super hard and still got bugs The acro that infected my system looks very similar to the one you pictured. It’s huge no despite being infested on and off for 18 months.
