What is the dilution rate for Terro-PCO Liquid Ant Bait?

I mixed up a dilution of 2% (a little more probably) and so far my ants are not interested, after several days. When I used the Terro that I bought at Lowes, they mobbed it within hours and swarmed it till it was gone. I saw a scout on my kitchen counter and placed a couple drops in front of him and he sniffed it and then walked away. What is wrong? Do I need to use it full strength so it is thick like the one I got at Lowes? Thank you.


The mix rate for Terro PCO Liquid Ant Bait is 1 part Terro-PCO Liquid Ant Bait to 5 parts water for a 1% dilution, or 1 part Terro-PCO Liquid Ant Bait to 2 parts water for a 2% dilution.  It should not be used in it’s concentrate form.   When using liquid/gel baits like Terro PCO Liquid Ant Bait, it is important to remember that ants change what they’re foraging for.  The go between carbohydrate based baits (gels and liquids) and protein based baits.  If they are not foraging for carbohydrates, they will avoid the baits at all costs.  We always recommend offering both baits so you always have a bait out that will appeal to them in whichever stage they’re foraging at.  Maxforce Complete Granular Bait is a great choice to add a protein based bait to your rotation.
