Other Options to Reduce Static Instead of Using Antistatic Spray

So my school is hosting a tournament this tuesday and we are having a problem on all 3 of our fields. The fields are generating lots of static. When ever we practice on them and I touch my robot, my finger will get shocked. This had actually caused 3 of my robot’s ports to burn out, and 4 of another team’s ports to burn out. What are some alternatives to anti static spray. I have heard of people using dryer sheets, but does that work?
