The bugs really don't go away until the first frost of the year. Of course as long as the Katy is, there can be frost in some places but not in others. My two biggest worries are mosquitoes and ticks. A quick goggle showed these:
Once temperatures start staying consistently below 10 degrees Celsius (50 degrees Fahrenheit), mosquitoes start to go dormant in preparation for winter.
Ticks can be active when the ground temperatures are above 45 degrees Fahrenheit.
If you are hiking, some DEET and proper clothing would be a good idea to ward off the ticks.
I rode the Katy last September after the temps got below 50°F and mosquitoes weren't an issue.
