Not sure from the slightly out of focus photo if your critters are centipedes or millipedes but I think they are millipedes. The other reason is that millipedes eat decaying plant material, and centipedes eat insects. If they are centipedes, they like to eat dead bodies of bugs.
If they are millipedes they eat decaying plants so unless your squash seeds have rotted then they will not bother them.
