Herag was not prepared to keep this insect from the Abyss Plane hidden, primarily because he did not sense much Bloodline Power from it.
He looked at it with the Eye of True Wisdom, and the Bloodline Power was very weak, without value for absorption.
Secondly, this incident occurred at Wendy's house, and it was something Wendy herself experienced firsthand.
Wendy is not a minor figure here, and many people will definitely know about this event.
Herag, being one of the people at the scene, will certainly draw attention as well.
In this situation, Herag certainly could not hide this insect for himself.
This is an insect from the Abyss Plane, what do you intend to do by hiding it yourself?
The Land of Dawn is very wary of the Abyss Plane, guarding against it very strictly.
If Herag dared to keep this insect, he would definitely be thoroughly investigated.
The normal course of action would be to immediately report to Serlandir and let them handle this matter.
