I'd be careful with this one. Like the others have said the ants would for sure appear 60ft above your head. Instead of raining down on you though, they would teleport back once they fall 10 feet. They would keep falling 10 feet over and over again, gaining speed each time, until they eventually reach the speed of light and travel through time to all bite you at once right before you buy that damned monkeys paw in the first place...
This will create a paradox because the ants couldn't have traveled through time in the first place if you don't buy the monkey's paw though, and this paradox will create a singularity in space time which will slowly consume the entire universe
All because you think bugs are icky
