choose for one charge 0 lines. In this case for the first one:


\documentclass{article}
\usepackage{pst-electricfield}
\pagestyle{empty}

\begin{document}

\begin{pspicture*}(-5,-5)(5,5)
\psElectricfield[Q={[-1 -1 0 0 ][ 2 1 0]},linecolor=red,
  posArrow=0,points=2000,Pas=0.025]
\end{pspicture*}

\end{document}
