I had been planting up my tubs on the patio and tipped out a pot with
an astilbe in, no plant but plenty of the above pests , on further
investigations a number of my pots had the vermin. I have sinced
removed all contents from the patio and have treated a couple of shrubs
in pots with Aprovel. Do these pests like the garden borders or is it
just pots? WilI ever be rid or am I stuck with them forever?
