Flea and tick year round?

[Leslie, Yogi & Maci Bear]

We are soon to be leaving the Midwest. Going to live full time in an RV as we travel this great country.
I've always given flea/tick RX six months of the year in Indiana. I'm wondering what everyone else does
in different climates. Like southern states, Arizona, Southern California, etc. Do we need to go to year round? Are there any other necessary preventative RX's that might be more important in certain areas?
Thanks!

Check with your vet as I think there is a coupon available for a pretty good rebate from the company if you buy 6 months or 12 months worth of Nexgard and/or Heartgard.  It may help bring the cost down so you can keep them on what they are used to.

 Since you will be traveling full time, leaving one climate for the other; I'd think it best to leave your animals on preventive.  I live in central Oklahoma surrounded by fields, for miles and miles ... I stop the boys treatment as soon as the first good frost comes in.
