Yikes! Well I'll speak for probably everyone on the forums, but this type of issue is not something that commonly happens, especially with a laptop (have dealt with issues like this on desktops).
What I do or recommend for users with a desktop computer is to open the case and clean it out, which is what you'll have to end up getting someone to do for you. While fumigating the computer and house will help kill the bugs. If there happens to be bugs in the laptops that end up getting killed having them in the laptop could be potentially bad for the internal parts of the laptop.
I'd suggest taking the computer to a local computer shop that can repair laptops and having them open the laptop and clean it out for you.
