We have hired exterminators and they have not worked to get the ant problem that we have under control. The ants are no longer in the house but as soon as the outside of the home that has been sprayed wears off they again show up in our home. We have located numerous nests and would like to handle the situation ourselves. Can you please advise us on the products that may be most helpful to control the outside ant population. We live in an area with a few smaller trees but very few. All nests that we have located have been in the ground and 1 in a stump that has been removed since. What type of treatment would you recommend to kill ants in the outdoor nests and to control our problem? The nests have all been located in mulched areas and two main nests with multiple other satellites have been found.
The good news is it sounds like you’ve done most of the work needed to solve this problem. As explained in our CARPENTER ANT CONTROL ARTICLE, knowing where nests are located can make solving problems easy. And based on your detailed message, you know there are several nests and you seem to know where they’re located. This is big.
At this point, I’d say all you need is the DRIONE, PHANTOM and TERMIDOR. Use a CRUSADER to get the Drione applied to any nest you see. This will kill the nest within minutes. The benefits of Drione are explained in our article and in this case should be able to handle 90% of the problem.
Next, spray the foundation with the Termidor. This slow acting active will get the ants by surprise. It’s non repellent and insects can’t detect it which makes it lethal. As they come to the home and start foraging over treated areas, they’ll be picking up the Termidor and ultimately bringing some back to the nests you’ve missed. Once the Termidor kicks in (which will take 3-5 days), these hidden nests will be shut down. This should take care of the 10% you miss with the Drione.
Lastly, keep the Phantom Aerosol for use inside the home. Phantom is like Termidor in that it’s slow acting and non repellent. Use it sparingly inside the home where you see ants. Phantom is unique in that it goes on dry and when applied properly, can’t be seen. I use it in my home which has nothing but hardwood floors. Even with all the shiny surfaces you can’t see anything has been sprayed.
Follow this process and you should have the problem resolved in a week. Here are direct products to the products and information listed above:
