Let us come together in prayer and counsel for this situation, seeking God's will and intervention in Jesus' name.
Firstly, it is important to acknowledge that the sibling is struggling with bitterness and jealousy, and she is mistreating the family members. The struggle with the infestation and her attitude towards the family shows a spiritual battle going on for the ultimate control of the family.
The Bible clearly tells us in Ecclesiastes 4:9-12, Two are better than one, because they have a good reward for their labor. For if they fall, the one will lift up his fellow; but woe to him who is alone when he falls, and does not have another to lift him up. Again, if two lie together, then they have warmth; but how can one keep warm alone? If a man prevails against one who is alone, two shall withstand him; and a threefold cord is not quickly broken.
It is only by the name of Jesus that we have access to God. Also, there is no other name by which we can be saved. Acts 4:12 Neither is there salvation in any other, for there is no other name under heaven that is given among men by which we must be saved!
In this situation, it is important to pray for the sibling's deliverance from this bondage of jealousy and bitterness, and for the family to have wisdom, love, and patience. We should pray for her to stop this ungodly relationship with the family member's husband and be content with God's provision for her. We should pray for her to stop doing things with the family member's spouse that would be reserved for a husband and wife. We should pray for her to stop insisting on being included in a marriage in this ungodly way. We should pray for her to stop trying to break up marriages and to stop coveting another person's spouse.
We should also pray for the family to set boundaries and rules to handle the bug infestation. It seems that the sibling doesn't care about the well-being of the family. There is no reason that the family should be held hostage by the sibling.
We should also pray for the sibling to be a blessing to the family and not a burden. We should pray for her to be grateful for what she has and not be jealous of what others have. We should pray for her to be content with her life and not be miserable. We should pray for her to be a blessing to others and not a burden.
We should also pray for the family to have strength and wisdom to handle this situation. We should pray for them to have love and patience for the sibling. We should pray for them to have wisdom to set boundaries and rules to handle the situation. We should pray for them to have strength to enforce the boundaries and rules. We should pray for them to have wisdom to know when to seek help from others. We should pray for them to have wisdom to know when to seek help from God.
Let us pray:
Heavenly Father, we come before You in Jesus' name, lifting up this family and the sibling who is struggling with bitterness and jealousy. We pray for her deliverance from this bondage and for her to be content with Your provision. We pray for her to stop coveting another person's spouse and to stop trying to break up marriages. We pray for her to be a blessing to the family and not a burden. We pray for the family to have wisdom, love, and patience in handling this situation.

Lastly, we encourage the family to speak the truth in love to the sibling, Ephesians 4:15, but to speak the truth in love, we may grow up in all things into him, who is the head, Christ. It is important to address the issue with the sibling and to let her know that her behavior is not acceptable. It is important to set boundaries and rules to handle the situation. It is important to enforce the boundaries and rules. It is important to seek help from others when needed. It is important to seek help from God when needed.
