What do you do if your coffee maker has cockroach?

Just boil a bottle water in a microwave or have your mom or dad to boi it on the stove and put suger if you like and coffee milk and pour it in but i think the best if you boil the water on the stove because it makes it nice and hot but if your parents aren't here and you do it with the bottel you have to reheat it but only if you put it 30 sec or less
