We investigate the possibility to detect neutralino dark matter in a scenario in which the galactic dark halo is clumpy. We find that under customary assumptions on various astrophysical parameters, the antiproton and continuum $\ensuremath{\gamma}$-ray signals from neutralino annihilation in the halo put the strongest limits on the clumpiness of a neutralino halo. We argue that indirect detection through neutrinos from the Earth and the Sun should not be affected much by clumpiness. We identify situations in parameter space where the $\ensuremath{\gamma}$-ray line, positron and diffuse neutrino signals from annihilations in the halo may provide interesting signals in upcoming detectors.
