With a B skill, yes they are. With an E skill (I've been leveling up Club recently, which is an E skill for THF), they only last until about 144 or so.
They AGGRO to sight, and PURSUE by scent. If you're invisible, they will not aggro you, but you can't Hide from them to shed aggro. Use Flee, use Deodorizer, then Hide.
It agros to SIGHT and SCENT!! that is why you got agro when you only used hide. BTW for people who don't know, Hide is a thf ability that gives you the invisible effect. So you need someone to deoderize you or bring some powders. I can confirm this is true. One of my party members were meeting my party at crawler's nest. Someone trained one of these and he used invis poweder and sneak powder and it still agroed him. He then got deoderized and he was fine. However, if you run by them really fast you will not be agroed due to scent, I heard.

Posted:Jan 04 2006 at 10:37 PM, Rating: Sub-Default, (Expand Post) They aggro sight, and then follow you by sight and scent. You only need to be invis to get by them no matter how "fast" you run. The deororize is for when they are attacking and following you already only. Nothing that I know of aggros by scent, it's a "tracking" feature when you already have aggro.
If you are talking about Invisible when you say hide... then you are saying what I am being told. Most everyone that I have ever talked to about Beetles say they aggro on sound. I am a level 41 WHM right now so I am playing it safe and wearing both sneak and invis when in areas with these bad boys. I will post if I possitively Identify either or.
