Terro Liquid Ant Baits Review

We’ve periodically experienced carpenter and black ant intrusions into the kitchen and bathroom, particularly during mild winters, and have used these   Terro Liquid Ant Baits   many times for a several years now to combat these pesky pests.

Over all, this form of ant suppression works great on the most common types of ants seen here, like carpenter ants, black ants, and European fire ants.  We find this specialized yet consumer grade insecticide well worth the cost ($3.98 for four baits currently at Walmart).

Terro Liquid Ant Baits Benefits, Features, Pros, and Advantages

Stop Ants at the Source.  This ant bait works by luring ants to the bait, and cart the chemicals they find there, back to their colonies, where many more ants reside, and where, the carried ingredients actually destroy the living ants.  Since the colonies are typically tucked well away from human sight, you won’t see many dead ants around as a result of deploying these ant baits.

Odor free, and Colorless.  The ant killing substance in the Terro Liquid Ant Baits is completely odorless and colorless (clear), like a thick water syrup.

Easy cleanup.  So even on the occasion that some of it spills out of the holder, cleanup is a cinch with a damp rag and mild soap.

Simple to install.  Usage of these ant killers is straight forward.  All you do is cut off the part where the red line ends on the plastic holder, and then sit the unit anywhere you need to control ants.

Easy to locate in stores.  The bright orange colored packaging makes this product very easy to find, even in large grocery stores and home improvement centers.

Take effect quickly.  Ants immediately respond as soon as you place Terro Liquid Ant Baits around.  Within minutes, they find it and begin crawling inside to the transparent liquid.

Low maintenance.  Maintenance is low on this ant killer.  Once placed, you need not disturb them (or the ants they attract) until the liquid inside disappears completely.  These baits remain completely effective until completely dry.

Can cure small to medium sized ant infestations.  According to the R&D department at Terro, each ant station has enough liquid to kill forty to fifty thousand ants.  Wow.  That seems like quite a bit for one bait.  Powerful stuff.

Ant infestations cured quickly.   Can completely remove all ants from problematic areas in a week or less.

Safe for humans and pets if used correctly.  When utilized and handled properly, neither persons nor pets ever come into contact with the active liquid ingredients inside the clear plastic casing, and the units emit no apparent caustic fumes.  We suggest placing the ant bait out of reach of children, as well as pets including dogs, cats, and indoor birds.

Terro Ant Baits Disadvantages, Cons, Problems, Limitations, and Concerns

Need better means of opening.  These pre-filled stations must be cut open with scissors prior to use.  They could simplify opening them with a flexible seal of some sort that covers the hole, that one could peel off.  But they might have chosen the package design requiring scissors purposely, to reduce the chances that a user would spill some of the active chemicals on his hand.  But this slight inconvenience by no means detracts from the usefulness and effectiveness of this product.

Easy to spill.  You need to be careful not to spill the liquid out of the station, as this can happen easily depending on where you place these units.  When spillage does occur, wipe up with a dry paper towel, and then, rinse the area thoroughly with water, several times.

A bit unsightly.  During deployment, many ants can congregate inside the ant bait.  Note that they do not die there generally, but go in there, pick up the insecticide, and take it back to their colonies.  So while the Terro baits are not technically an ant trap, many ants do visit them; particularly during the early days of the bait deployment.  So, if you’re squeamish about seeing lots of living bugs crawling around, you’ll want to position these baits along the typical travel routs in your ant infested places, but well out of sight.

Frequent monitoring needed.  Especially in larger infestations, the active chemicals can run out much sooner than expected.  During the first week or two of deployment, we recommend checking the ant baits once every day or two and replacing them as needed at those times.

Our Rating

So We’d highly recommend   Terro Liquid Ant Baits   for any in-home ant trouble.  They’ve worked well for our family, and we’d feel that this ant killer product is the best performing one that we’ve tried for controlling ant problems indoors.
