Need Recommendation for exterior & interior perimeter sprays. Have been in my home 14-years. Now persistent small black ant infestation. Continuous battle. Used "Terro" baits followed by electromagnetic-ultrasound repelling devices. Killing many, many ants and 95% of centipedes. But new live ants are seen each day.

Please take a look at the following Extension publication called Ants and Their Control: http://www.extension.umd.edu/sites/default/files/_docs/programs/hgic/HGIC_Pubs/HG7_Ants.pdf
It will help you to figure out where your ants are coming from. You may need to focus on plugging cracks and crevices around your foundation or windows/doors with caulk or extrudable foam.
We do not recommend perimeter sprays, especially indoors for ants, which are a nuisance, but are harmless. Keep up with the terro gel baits, and at this time of year, you could also use a combo bait (looks kind of like a small hockey puck) which has a protein source which they may prefer in the spring.
