You take Irish spring soap *no other brand* and "shave" slices off it. Leave the thin slivers around the garden. To use it on trees cut the bar into quarters then use a metal skewer (like a shish kebab stick) to poke a hole through the quartered piece. Thread some dental floss through the hole and tie several to branches of the fruit tree. The scent of the soap is more than enough to deter the pests away from your garden and protect your trees all season long!
