My suggestion was to spray masking tape away from the scope & when dry put on the outside of the OTA tube..Not inside.. also to use a surface spray not fly spray. Surely nobody would be that silly to spray inside their scope..
The idea is to kill spiders to stop them getting in the scope in the first place.
