A preventative device against nuisance from birds comprised of a base to which spikes are fitted to extend opposite surfaces of a structure to be protected in order to discourage birds from landing on those surfaces. The base is provided with canals and each spike has a knurled end. The maximum cross section of the knurls is slightly larger than the cross section of the canals. The spikes are force fit into the canals so as to be held firmly therein.
