2 Kings 6:30 Then Jehu went to Jezreel. When Jezebel heard about it, she put on eye makeup, arranged her hair and looked out of a window. 31 As Jehu entered the gate, she asked, “Have you come in peace, you Zimri, you murderer of your master?”[e]

32 He looked up at the window and called out, “Who is on my side? Who?” Two or three eunuchs looked down at him. 33 “Throw her down!” Jehu said. So they threw her down, and some of her blood spattered the wall and the horses as they trampled her underfoot.

34 Jehu went in and ate and drank. “Take care of that cursed woman,” he said, “and bury her, for she was a king’s daughter.” 35 But when they went out to bury her, they found nothing except her skull, her feet and her hands. 36 They went back and told Jehu, who said, “This is the word of the Lord that he spoke through his servant Elijah the Tishbite: On the plot of ground at Jezreel dogs will devour Jezebel’s flesh.[f] 37 Jezebel’s body will be like dung on the ground in the plot at Jezreel, so that no one will be able to say, ‘This is Jezebel.'

I don't think this needs commentary. I got this from Enduringword.com.

Is it peace, Zimri: Jezebel called Jehu Zimri after the man who assassinated King Baasha of Israel (1 Kings 16:9-12), when Zimri was also the servant of Baasha, a commander in his army. It was her way of calling Jehu a despicable rebel.

It was also an implied threat, because the brief reign of Zimri was ended by Omri, who was the father of Ahab and the father-in-law of this same Jezebel. By implication Jezebel said, “The dynasty of Omri will defeat you just like it defeated Zimri.”

“Doubtless Jezebel’s adornment was intended to create a queenly appearance in the face of impending death and served as a royal burial preparation.” (Patterson and Austel)

“Her innate vanity manifested itself up till the last.” (Knapp)
So they threw her down: The eunuchs at the window probably worked for Jezebel, but they quickly responded to Jehu’s request for support. They probably had long despised this wicked, pagan queen.

Jehu emphatically answered her question about peace. “There cannot be true peace so long as we permit the infidelities and charms of some Jezebel of the soul-life to attract and affect us… Whatever its charms, it must be flung out the window before we can be at peace.” (Meyer)

He trampled her underfoot: In ancient near eastern cultures, this desecration of the dead body was a fate worse than death. Yet Jehu was completely untroubled at the ugly end of Jezebel; he ate and drank after trampling over her dead body and passing over the pavement splattered with her blood.

“Her brains, that devised mischief against the servants of God, are strewed upon the walls.” (Trapp)

This is the word of the LORD: God’s promise against Jezebel and the house of Ahab was exactly and righteously fulfilled (1 Kings 21:19, 21:23-25).

“Jehoram’s blood manureth that plat that was wrung from Naboth, and Jezebel shall add to this compost. Oh, garden of herbs dearly bought, royally dunged!” (Trapp)

Yet as the house of Jehu became corrupt, it also would face judgment. Hosea 1:4 speaks of judgment to come upon the house of Jehu: I will avenge the bloodshed of Jezreel on the house of Jehu, and bring an end to the kingdom of the house of Israel.
Blood splatter.... but her eyes were done.... I'm not so sure they added any taste for the dogs.
