/diy/ - Do It Yourself

Hey /diy/, not sure if this is entirely on-topic, but I know you all are a knowledgeable bunch.

TL;DR: How to best kill and clear roaches and eggs from valuable electronics, especially gaming consoles, laptops, desktop computers/components, and large televisions.

So we have been dealing with a light but persistent roach infestation in the apartment I live in for months. I will be moving in a month to a new place, and want to guarantee none of the bugs follow us to our new place.

I've been doing research all morning to figure out how to prevent this. We already got an exterminator for the place, will be leaving many replaceable appliances behind, thoroughly washing and hot drying all the fabric things we have, and disposing of old carpets, mattresses, and couches. I'll be washing and treating all furniture we bring like bureaus and desks and tables. Dishes and the like will all be washed and packed immediately.

I'm VERY concerned about my laptop, expensive gaming rig (which I'm SURE is housing some critters), and fancy 4K 55" TV. Especially the TV I'm worried about treating, as the computer I'm used to taking apart and rebuilding. I'm thinking about applying some boric acid around the TV and computer for the time being, cleaning them with strong isopropyl alcohol, and using a gel treatment around the inside of my computer case and the TV's vents and openings.

Has anyone dealt with this before? How do you take care of your large electronics, especially before a move?
