I applied it once it’s not working?
As per the label directions keep applying if activity is still seen.
Bifenthrin, the active in Richgro Ant Killa, works by contact so it is important to apply the product to places where ants are highly active such as the actual ants nest and ant trails.
When ant activity is seen apply Richgro Ant Killa around the nest and along any ant trails. A light watering in of the sand granules will activate the chemical and also wash the granules deeper into ant nests and or ant trails.
Note that this product is not a one application product, application is required until all sign of ant activity is gone. For heavy infestations apply at the high rate as described on the label.
For really heavy infestations the combined use of Ant Killa Granules and Richgro Ant Gel may assist in eradication of the infestation.
How does it work?
It’s a contact stomach poison.
What is the active in the Killa range?
Does Bifenthrin contaminate ground water through leaching?
Is Bifenthrin a residual chemical?
Yes. But, it has a short “half life” in soil.
Is Bifenthrin absorbed by plant foliage?
Can Bifenthrin be used around pets?
It is recommended to use with caution around pets. Do not allow pets in areas where product could be consumed.
Why is sand used as the carrier?
It is more effective as the Bifenthrin is dispersed more efficiently.
Does it have an odour?
Yes. But, it is not unpleasant.
Does it matter if it gets wet/ should I water in?
Don’t be afraid to add a little water and wash the product into the gaps and crevices where ants love to hide.
