Going to fix roach infested Wii that wont turn on help pls.

I bought a Wii off of my friend for 10 bucks, working and everything, what a deal haha. Well now I have a problem on it. Its happened 3 times now and only got worse, one day the Wii was just dead, fortunately I found the AC Adapter reset that made it work again. Months later, it happened again, and well I tried the AC Adapter reset to no luck so I thought this time the Wii was dead for sure, though when I plugged in the adapter to the Wii the power light will turn on and then off, just a little blink, but wont stay on long enough to turn on the Wii, so it sat there unplugged and all for almost 2 days,and I decided to give it another shot, and it worked!

Months later, it started to do this think at least once a week, or once ever 2 or 3 weeks that I would randomly find it dead, but I would just unplug the AC from the back of the Wii and back in, and it would work again, I then stared to consider another AC Adapter but never got around to it, untill yesterday that the Wii died, again, and the AC Adapter wouldnt work so I went and bought a brand new AC Adapter from my local Gamestop, and well it didn't work, I then saw a roach come out of it from the cooling fan in the back and I then decided to use a flashlight on the Wii's AC Connection, and well surely enough through the little holes I saw a roach there.

While in the outside of the conection there isint any roaches squished or anything restricting the connection or the flow of electricity, and only seem to be inside, are they the ones possibly causing the Wii's power outage? I don't think its dead since the power light blinks on and off but wont stay on to turn on the Wii. Its also not bricked, I highly doubt it. I have a metter I can use to check it and stuff, but do you guys think they are the problem, im still gonna clean it, I dont want no reaches neer me. Just want to see what you guys think and if that would fix the problem.
