Combating malicious bot traffic[ Edited ]

I see lots of strange traffic on a website I work on that I can't explain but seems like fake traffic. This isn't related to analytics spam, I don't think, but we do all the best practices with regard to that: checking exclude bots in the view, filtering out hostnames that don't match our website, etc. I still see very high, unnatural spikes in traffic that I can't explain. For example, I'll see mass traffic come in from users only on IE7 for a short period of time.
Or in this example below, Here is Organic Search traffic entering on the homepage where Java support is No, comparing year over year September:
I should also mention that the bounce rate of the segments that make up these traffic spikes, regardless of the other characteristics, is close to 100%. What can explain these traffic patterns? And how do we combat it if it isn't real user traffic patterns?
