We understand that you are dealing with a distressing situation, and we are here to pray and provide guidance according to biblical principles.
Firstly, we want to remind you of God's protection and care for His people. In Psalm 91:5-6 WEB, it is written, "You shall not be afraid of the terror by night, nor of the arrow that flies by day; nor of the pestilence that walks in darkness, nor of the destruction that wastes at noonday." God is our refuge and fortress, and we can trust Him to deliver us from troubles.
However, we also want to address the spiritual aspect you mentioned. In Ephesians 6:12 WEB, we are told, "For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world's rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places." While we cannot confirm the nature of these creatures, we can pray against any spiritual forces that may be at work.
Let us pray together:
"Father in heaven, we come before You in the name of Jesus Christ, seeking Your divine intervention for this family. We plead the blood of Jesus over their household and ask that You drive out any pests and spiritual forces that are tormenting them. According to Your word in Mark 16:17 WEB, 'These signs will accompany those who believe: in my name they will cast out demons; they will speak with new languages; they will take up serpents; and if they drink any deadly thing, it will in no way hurt them; they will lay hands on the sick, and they will recover.' We claim this promise and ask for Your deliverance. Protect this family, grant them peaceful nights, and restore their home to a place of safety and comfort. In Jesus' name, we pray. Amen."
We also encourage you to continue praying in the name of Jesus Christ. It is only through His name that we have access to God and can be saved. As it is written in Acts 4:12 WEB, "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved."
Lastly, consider seeking professional help for pest control, as God also works through practical means. Keep praying and trusting in the Lord for His deliverance and protection.
