How to Prevent Fire Ants

Fire ants cannot be entirely eradicated since it is impossible to treat all infested areas. That is why the current goal of pest management services is to overwhelm these ants as much as they could with biological control procedure and only utilize herbicides where it is environmentally and economically friendly to do so. 

 Fire Ants

There might not be 1 “greatest” way for controlling fire ants in Hawaii, especially in areas that are large. The goal must be to look for the methods that are inexpensive and environmentally friendly. Doing nothing is possibly one option in places where these ants do not show complications.  

Broadcast Baits 

The applied bait shows how ants will be controlled quickly and how much time does it need for the effect to last. Bait products that act faster include Spinosad (works in few weeks), hydramethylnon (works in 2 up to 4 weeks when broadcast and 6 up to 15 days for mound treatments), and indoxacarb (works in 3 up to 10 days). They might require to be applied again more frequently than longer lasting and slower acting products like pyripoxyfen, methoprene, fenoxycarb or abamectin. These products usually work in 6 months when applied in fall and 1 up to 2 months when applied in spring. 

Products that mix slow and fast-acting ingredients, like hydramethylnon plush methoprene might control fire ants since they quickly act and last longer.  

Long Residual Contact Insecticide Treatments 

A contact insecticide is applied to the landscape surface and the lawn with this method. This is very pricey than other control ways. However, it might be more efficient in areas that are smaller since fire ants that move into the applied areas would be eradicated as long as the treatment is active. Granular products are better applied with a fertilizer spreader that is a push-type. It should also be watered in after applying.  

Granular fipronil products are slower acting. However, they last longer. Every year, you will only need one treatment. On the other hand, faster-acting contact insecticide, like pyrethroids, could remove ants for months. However, it might not eradicate colonies living deeper underground. 

Single Mound Treatments 

It is a great method for small areas with several fire ant mounds or where you want to preserve native ants, even though individually treating ant mounds may use more insecticide and requires more intensive labor than other approaches.  

Faster acting bait products such as Spinosad, Indoxacarb, and Hydramethylnon could be utilized to treat single ant mounds. They are also great for treating colonies that are not accessible, such as those nesting at the bases of tree trunks, in plant beds, and under sidewalks. Several mound treatment items are available as granules or dust, injectable aerosols, or liquid drenches that re watered into the mound. Proper application is important since ants are only eradicated if the insecticide contacts it. These treatments are very efficient when the fire ants are living close to the surface of the mound. During treatment, colonies must not be disturbed.
