Antfestation

I've got a bit of an infestation of ants in my room. They're coming from the wall behind my desk. My dad vacuumed and put ant killer on it, but I'm absolutely terrified of bugs of any kind. Spider, yeah, no. Get away from me. Butterfly, pretty, but don't go anywhere near me. Ants, maybe one or two, more than that, nooope. I can't get an exterminator because my parents are saving up for a big move in July, across the country. Also, I'm a young teen, so I can't do anything myself. I'm terrified I'll wake up or some home from school today to see them covering everything, or see them in my bed in the morning. I understand they can't hurt me, I don't know why I'm scared of them but I am and I can't help that. My parents don't understand, they think it's stupid. What do I do? Thanks for any advice ^^
