Yes, ants do have something similar to blood called hemolymph but it is not red in color like humans have.
In ants, hemolymph is a fluid equivalent to the blood which is responsible for the exchange of material such as nutrients and waste materials. Ant’s blood that is haemolymph does not transport oxygen and thus, does not have red blood cells.
It is generally clear or yellowish or greenish in color but not red because it does not have red-colored hemoglobin similar to human blood which carries oxygen.
