Yes, you have to explicitly delete the vectors you allocated using new.
But that's not enough.

Try running the following code

C++
#include <iostream>
#include <vector>

using namespace std;

class thing
{
public:
  thing(){cout << "thing ctor\n";}
  ~thing(){cout << "thing dtor\n";}
};

int main()
{

  for(int i=0;i<3;i++)
  {
    vector<thing*> * Nodes = new vector <thing*>();
    thing * Athing = new thing();
    Nodes->push_back(Athing);
    //do stuff
    Nodes->clear();
    delete Nodes;
  }
}
