So the ants are back in droves this year - any pest control techs out there? Most years they show up when we get some heavy rain or extended dry periods and they are searching the kitchen. Normally my mix of boric acid and simple syrup (sugar water) nips them in the bud in a few days, or in a worst case scenario I sprinkle some food grade DE (Diatomacious Earth) along the window sill and base boards for a day or two and no more ants. This year we are getting hit hard - the typical small black ants (argentine I think) and some that are slightly larger, also they are showing up everywhere - bathrooms, kitchen, living room and bedroom. They seem to be taking the bate and keep on coming this time around. I think my next step is to clean out the gutters again (found an ant colony up there a few years back and they were gone for the season after a clean out), spray around the foundation with some of the home defense stuff and see if that helps. Any suggestions on how to permanently rid ourselves of the ant hordes would be greatly appreciated.
