Normal to see bed bug after extermination?:

I spoke to an exterminator about this and he said all they could do was
heat up the whole room to kill them. They do not have an effective
insecticide since things like DDT were banned.

Doesn't heating to such high temperature damage electronics like TV etc?

Yes, but the EPA doesn't care about that; or the bed bug infestation
for that matter.
