“Wanted to deter the squirrels (& other mammals particularly rats). Have been using chilli powder to mix with suet pellets & seed, it works until the rain washes off. Have given it 4 stars as I have not been using it long ( 7 days), but have to say early signs are positive. Grey squirrells visit frequently,they wreck feeders, the garden, & eat everything. Small pieces have survived overnight on the ground & the squirrell has ignored, so can only assume it works.
** Perhaps Ivel Valley could consider doing a pellet mix containing chilli also **”
