Hi, I haven't quite followed this line of thought...being new...but do "we" want to get rid of the ants if THEY tell us something may be up...& spraying was mentioned? So far & here on the East Coast, I have a few Magneto Sonic (pest & insect repeller) plugged in around in my house & don't seem to have an ant problem.
I might add, I bought one just for the outside (squirrels in birdfeeders) & the one squirrel that always made it to the feeders must of been deaf...it didn't "stop" him! So now w/this mosquito problem in NY & yesterday read in FL...I have just taken the feeders down. Char in VA
