If there was some kind of repellant added to the painting, what would be his motivation? Well, if such were the case, it's possible he is merely looking for attention. It is also possible there is no repellant. The point being is that the Bible condemns idolatry and whether it was a super natural event (it was not one of God) and if it was not fraud, then the bees by their very nature are avoiding something they know to be bad by instinct (i.e. because God desires His creation to worship Him in spirit and in truth and He does not desire them to look to false idols or idolatrous imagery).
Side Note:
Also, if there was bee repellant (such as mint) added to the painting, you said that this would endanger the man's income by doing so. Actually, it is the exact opposite. Doing such a thing would make him more popular by creating a miracle. For who is going to really care to check and or investigate to see if such a miracle was false? The chances of such a thing happening are pretty slim.
And if someone did challenge him and he was not honest in the beginning (and he continued to be dishonest - hypotheically speaking) he could deny it and say that he was unaware that there was mint used in the painting. He could then blame it on the paint company and shift the blame to them.

1. Yes it would endanger his income, because income is based on supply as much as demand. Endangering your supply is stupid if you want to make money.
2. You do not know it wasn't from God
3. Iconography is not idolatry, and your saying it doesn't make it true. Scripture doesn't say it's idolatry. You do. IT is your personal interpretation of Scripture.
4. Because of the fact that number 3 in my list is true, you cannot declare that it isn't a miracle from God. Either that, or you're accusing Christians of praying to Satan. So go ahead, tell me that Orthodox Christians are praying to Satan. Say it, or retract your words. Because of the fact that the first thing we do is assume there is a demon involved in a miracle, we exorcise the object(s) in question. When the miracle continues, you must assume that either we are praying to Satan, or God doesn't have power over demons, or that the faith of Christians is not enough, in combination with the amount of fasting and prayer, to cast a demon out of anything. Because the third cannot be true because Scripture says it isn't, and the second is like the third, we are left with the first. Logically, you accused the Christians that consider this a miracle of praying to Satan himself, or at the very least, someone that serves him or a false god. I would be careful with your accusations.
The best way to know if it is a miracle is the answer to the following question: Does it bring people to Christ. And the answer in the case of the beeswax icons is a resounding "yes!" This miracle brings people to God. It draws them closer to Christ. Therefore, it cannot be of the devil. The answer to your accusation of it being of Satan is the same as the answer Christ gave when accused of serving Satan:
And if a kingdom be divided against itself, that kingdom cannot stand. And if a house be divided against itself, that house cannot stand. And if Satan rise up against himself, and be divided, he cannot stand, but hath an end. No man can enter into a strong man's house, and spoil his goods, except he will first bind the strong man; and then he will spoil his house.
If Satan were performing this miracle, or the miracle of the Iveron Icon's streaming myrrh, or of the Kursk Icon (one of which happened to the Matushka of the Church I was baptized at), then Satan is rising up against himself, for he turns people to Christ.
