One other irritating trick that might stall them for a turn, is to block all paths to your warp points with something visible, even an unarmed satellite. The movement AI will then not move through those sectors unless the enemy specifically orders to move into each one in turn. This can stall them for a turn or two, or more if they don't notice and/or don't realize what is happening. It's kind of a gamey tactic, though, and if they do order each sector of movement, it won't slow them down at all.
