Papaya Zoap Auto - Sweet Seeds

The first sign of pests this year - and I can't grumble because the plant can still be (mostly saved) Plant 2 is infested with some sort of eggs of god knows what insects. Luckily the branch structure was so restricted and upward that it hasn't spread them to the other plants. I did a thorough check and it's just this one - but it has been hit hard in places (see photo) The other two look fine. I knew I should have sprayed them with neem oil - I just never got around to it.
