Question DetailsAsked on 6/20/2017

Would rope lights keep bats away from roof tiles?

Bats are crawling under the edges of my roof tiles.

I very seriously doubt it - they come and go with bright yard floodlights on anyway, and the light is not really the issue (they fly around our area up to a couple of hours before sunset) - they fly at night because that is when most of the insects are out, not because the light prevents them.

Here is what I think is a really good article on bat removal and prevention FYI -

I have never heard of bats actually living under tiles - so unless they are finding an entry point into the attic under the tiles it might be they are just searching out holes during the nesting season (we are at the start of normal nesting season) the same as bees and hornets and such do looking for a suitable nesting spot, but will not stay unless they find a "bat cave" environment. Their entry/exit holes usually have a pretty clear evidence with brown bat guano staining and droppings at it.

Normal solution - easier done when tiles are first installed but can be retrofitted - is finding where they are nesting and making sure they are all out bedfore you seal the entry hole(s) - including getting babies out, or not doing the sealing during the summer to late fall months - then metal screening or polyurethane sealant (available in several different colors) to seal the entry holes. If the entry is under the bottom row of tiles wire mesh should be used, because filling that with sealant could cause backup of any water coming down through the tiles to exit there.

Pest Control - a bat specialist if an area where they are a significant pest issue - would be your Search the List category to get a contractor to come assess your issue and give you a quote to fix it.
