Fluon question

[UnrealSparks]

I've been using fluon for a couple of days now and it's working really well letting me to leave my nests open for good ventilation.
But how often should I replace the barrier to keep its efficiency?

I would think in dry areas you wouldn't need to replace the barrier very often at all, but I would just replace it once every one to three months to be safe. I'm open to any corrections, for I only have knowledge of fluon on youtube.

You wouldn't need to replace the barrier, but I would just replace it once every one to two months to be safe. I'm open to any corrections, for I only have knowledge of fluon on youtube.

Alright, thanks! Sorry for the late response but I've been very busy with university.
One last question tough. When I'll be replacing the barrier will I have to put more fluon over the old barrier or remove the old barrier first and then reapply it? Because I read that applying multiple layers on top of each other may cause some weak spots where the ants can grip on.

I would just remove the old fluon first, and then apply the new.

Nice! Thanks a lot!
