Phantom II Aerosol would be a good choice for you. Phantom should be applied around baseboards, door frames, window frames and places where utilities (cables, pipes and wires) enter through the wall as these are the most likely places for the ants to enter/exit. Phantom is a non-repellent insecticide that has a delayed reaction which allows ants time to get back to the colony and spread the product. In essence, the ants will not be able to tell that the product is in place and they will pick it up on the fine hairs all over their body and inadvertently carry it back to the colony where over a course of a few days it will knock out the entire colony. Phantom works really well because you don't have to worry about whether the ants will all take the bait, they just need to walk over the treated areas. Please see our Ant Treatment Guide for more tips and information.
You can use Phantom Aerosol spray in the same area as other products like MotherEarth D. Phantom Aerosol Spray is ideal for cracks and crevices and has been proven to be very effective against bed bugs.
It can take several months to get rid of a large infestation. Infestations do not get large quickly and unfortunately they do not go away quickly either. Below you will find our best recommendations for eliminating roaches:
The Roach Control Kit #2 is perfect for roach control problems in homes and apartments. This professional kit includes 1 packet of Demon WP Insecticide (which makes 4 gallons of finished solution) for spraying the outside perimeter of the home and inside underneath appliances, behind cabinets, under toilets and sinks, etc. You'll also get 4 x 35 gram tubes of Invict Gold Roach Bait Gel--one of the best roach baits on the market. Invict can be applied up high in the kitchen in the corner of cabinets and in cracks and crevices in kitchens and bathrooms. The bait contains a slow-acting poison that attracts and kills feeding roaches, who also spread the bait to other roaches by contact or by sharing food. Finally, 20 Gentrol Point Source stations provide an IGR (Insect Growth Regulator) that will stop roaches from laying eggs, helping to halt the infestation. The combination of an IGR with roach bait is a highly effective roach control strategy that is widely used by pest control professionals. Demon WP must be applied with a 1 gallon pump sprayer.
Here is a link to a great article that really goes into depth in explaining a roach control program.
Phantom II Aerosol Spray does not list all species of ants which it controls on the product label but will work for carpenter ants. It will work like a bait in that it is taken back to the colony and spread from those ants that contact a treated surface.
