At present, an infestation can kill people with no chance to save them. Hives appear, bugs appear, and if they're too close when they spawn in there's nothing the player can do about it.
There is an easy fix and a harder (but cooler) fix. The easy fix is to have the bugs appear ~5-10 seconds after the hives appear just to give the colonists a chance to get out of certain death. The harder fix is to have the hives appear inside the mountain near the excavated areas and then mine their way into the base.
Compare two scenarios: the first is what we've got already. Bugs appear out of thin air in Bob's bedroom and Bob is dead before he can do anything. The others rush in to help, but killing the bugs before they kill Bob just isn't going to happen. Might as well just have an event that drops a meteorite on one of your pawns for all you can do about it.
The other scenario is an infestation warning. Bugs are trying to break through the wall into Bob's bedroom. You assign Bob to repairs on the wall; it won't hold forever, but it slows the breakthrough down enough that the others can rush into Bob's room and get set up to unload everything they've got into the chokepoint before the bugs can spread out inside the base.
Bugs appearing out of thin air and killing your guys isn't fun or fair, and there's nothing the player can do about it. Giving the player an opportunity to react, even if it's a fairly short window, is exciting. Scrambling to set up a firing line before a tide of bugs breaks through the wall is awesome. Increase the number of bugs as necessary to maintain an appropriate challenge.
