Tips

Put up ~20 at a time
Take old flyers down as you go (especially ones referring to past events such as food drives)
Tape: 3 horizontal, 1 vertical
Check for weather, use more tape if it will rain soon
Targeting locations based on what flyer is, i.e. a food drive flyer should go near where the food drive will take place or people who might donate food might frequent
Put a lot of flyers close to each other, seeing it 2x helps people remember, repetition is key
Put flyers up on street as well in businesses/community centers, i.e. grocery stores, bodegas, laundromats, churches, etc.
Disinfect your hands and flyering supplies frequently, especially after touching surfaces, see this Flyering Safety Protocols document from QueerCare published in March 2020
