Formidor®
The high efficacy ant bait for complete colony control. Effective against Garden ant (Lasius niger), Argentine ant (Linepithema humile), Erratic ant (Tapinoma erraticum), Pavement ant (Tetramorium caespitum) and Invasive garden ant (Lasius neglectus).
Formidor® is a ready-to-use bait for professional use that draws on the proven high efficacy of fipronil in very small doses.
The sweet taste of the gel bait is highly attractive to ants who ingest it and rapidly share it through the entire colony.
Benefits
Formidor® offers four key benefits for complete colony control.
- Proven, low dose fipronil efficacy
- Irresistible sugar rich formulation
- Rapid and complete ant colony control
- Quick and easy to use in and outdoors
Why Formidor®?
Proven, low dose fipronil efficacy
Formidor® brings the proven insect killing power and reliability of fipronil to the professional European ant control market. It is well known as being the active ingredient in the leading cockroach bait, Goliath®. In contrast to either organophosphates and carbamates or pyrethroids, fipronil acts on the GABA-regulated chlorine channel between neurons, decreasing the periodic inhibition of electrical impulses and leading to death through over excitation.
Irresistible sugar rich formulation

Research and experience confirm that the gel bait’s carbohydrate-based formulation is particularly attractive to ants.
Foraging ants cannot detect the insecticide’s active ingredient, making Formidor® irresistible. The bait continues to be both attractive and effective over an extended period, and therefore readily consumed. It is then rapidly transferred back to the nest to feed the entire colony through the communal food sharing behaviour of trophallaxis.
Rapid and complete ant colony control
The 0.05% concentration of fipronil is carefully balanced to ensure that ants consuming Formidor® have sufficient time to share the palatable rich bait widely throughout the colony before succumbing. Research shows the insecticide begins to have a lethal effect between 12 and 24 hours after ingestion. Adults, larvae and queens consistently die following even low levels of consumption, leading to complete colony collapse within 10-14 days. Activity is more rapid and complete than with other commonly used ant control insecticides.
Quick and easy to use in and outdoors
Formidor® is a ready to use bait, which is quick and easy to apply to infested areas. The gel formulation enables precise targetting and does not require dilution or spray equipment. Designed for use by professionals both in and around domestic and commercial buildings, it is virtually odourless to humans. When used outdoors, the product should be placed in bait stations or, when not possible, applied in cracks and crevices, to be protected from rain and minimize access to non-targets.
Who will benefit from Formidor®
Ant control in bars, restaurants and cafés

Customers enjoying a meal at a restaurant are likely to be uncomfortable about seeing colonies of ants marching across the floor. The effectiveness and speed with which Formidor® acts will be welcomed by a range of hospitality venues.
Food related industry
Ants can make their appearance wherever food is processed, packaged or stored. Once a food source has been located, their colonies grow rapidly. The quick, easy and targetted application of Formidor® contributes to a swift resolution of the infestation.
Ant infestation in residential buildings

Ant trails are typically located in kitchens and dining areas, where sugary food is readily available. Formidor® takes advantage of the ants’ characteristic food sharing behaviour to treat the entire colony.
Pest control operators (around buildings)
The highly effective and easy to use gel bait offers pest controllers an effective tool as part of the integrated pest control management strategy.
