Hello All, long time no talk

Hopefully with the summer holidays FINALLY here, I will be on here more frequently. I sure do miss my YT family.
I am looking for help from FL members. My parents bought a house near Punta Gorda and Layla will be living there for 3-4 months of the year (December- March-ish). The longest we have ever stayed is 2-3 weeks so I am needing help with some questions.
Layla will be on Interceptor for heart worm while she is there, not something we usually need in the winter months in Canada
I am just looking for any other info I might need to know to keep her healthy while she is there. I will most likely not be there for the full 3-4 months as I will hopefully be teaching. Are there certain bugs that we need to watch out for? Plants that are harmful? Any additional info I can get would be great!
