In truth, Invisible Arachnids aren't significantly tougher to deal with than the Adult versions, as they have the same number of Hit Points, the same Toxic damage potential, and attack with the same swarming and leaping behavior. It's easy to justify spending ammo on these guys, especially in the late game when it's plentiful, though it's recommended you save any Worm Clusters you might have for the massive number of Rumblers you'll encounter later on. As always, keep several Anti-Toxin Hypos on hand, or you'll suffer long after your enemies are dead.
Invisible Arachnids are not invisible to the "Sense Motion" Psi ability. They also don't respawn, and they're not very plentiful to begin with. So keep your radar active the first time you're moving through levels and you should be fine.
- Research an Arachnid Organ (requires a small amount of Iridium) to give you a damage bonus against all types of Arachnids.
