Bats exclude or leave them alone?

[LannaGuy]

got about 8 of these in my roof space - this must have been a lost one that I found dead this morning on opposite side of the house

 

would you let them be or get rid of them?

Got a few in a small roof extension over 1 window. No access to the main space so I just let them be.

Most nights I see about 6 leaving around dusk.

If they are in the space between roof and ceiling then you must get rid of them.

If you do not, their foul smelling and caustic excrement will eat through and collapse the ceilings.

I speak from bitter (and expensive) experience.

However many bats you think are there, the actual number will be at least 10 fold that.

They are hard to get rid of, took me 2 years. What finally worked was a combination of 24 hour lighting in that space plus mesh all around where the roof tiles meet the house. When applying that, put on the last bit just at sunset after they've flown out, otherwise you'll trap some inside which is not what you want.

The ones I've got have no access to the main roof area only an add on roof over a window so don't bother me that much. If they were in the main roof then they would have to go.

oh... they are in the slate overhang not in the actual roof space... I had thought of putting some mothballs in there which might deter them but if they were harmless it's quite nice to see them fly out nightly (around 7 or 8)

 

PS but i'll go up and make sure I'm correct about not in the roof space itself as your cautionary tale warrants a more serious look - thanks
