Dispense a line of gel that completely blocks any paths the ants might take to get to the feeder
Tips
To avoid disturbing gel, place away from the feeder on locations that a bird will not perch or contact
Works best on non-porous surfaces like metal or plastic
If you must use on a porous surface, place adhesive tape securely on surface before dispensing gel (this will protect the porous surface from staining while maintaining the effectiveness of the gel)
Do not use on surfaces that can be damaged or stained by oil
