However, there are a couple of downsides to be aware of in baiting for ants:
- Since the bait is so attractive to the ants, the activity may actually get worse in the short term because it draws more ants to the bait. It's not uncommon for me to get customers calling back a day after I've treated their house, complaining that there are hundreds more ants than before I arrived. You just have to be patient; this swell of activity subsides within a few days.
- It may take longer overall to stop the ants. Again, patience is the key. The only times I see Terro fail to get rid of ants is when the customer gives up too soon. When solving an ant problem, there are four generations of ants to kill - the adults, the pupae, or those in a cocoon stage, the larvae, and then the eggs. You have to have the bait available until all four life cycle stages in the ant colony you are hosting are eliminated. This can take anywhere from a few days to eight weeks (worst case scenario). Though each life cycle can take around two weeks to complete, without the proper care from adult ants, the eggs and larvae often perish on their own.
One final note: When using Terro liquid bait to solve your ant problem, you need to make sure you reduce all other food sources, so that the bait is the only thing available to them. This includes pet food, hard candy on the coffee table, dirty dishes, and crumbs on the floor and counters. If the ants have other sources of food, it will take dramatically longer to kill the ant population.
