I wouldn't attempt to remove anything until 1) you know exactly what it is and the cause 2) you know you can do so without causing further injury/stress to your little male 3) you get your vet degree!
Seriously, don't attempt to remove it. If it's a cricket bite, it will probably heal by itself. You can dab a bit of Bactrin or Neosporin on it, and keep an eye out for infection or further swelling. Oftentimes, we unintentionally cause more stress and damage with our good intentions
