Hey Guys --
I've posted a thread or two about this over the last few months, but I figured I'd start a new thread since my question is alittle different.
Basically our problem is over 3 months ago we found our house was being invaded by fire ants coming up through the sand trap under one of our bathtubs. Our bug guy, who has already rid the yard of ants and about any other type of insect, used Termidor which seemed to kill them there, but now they're entering through any other opening in the house they can find, like around the toilet, under the second bathroom sink, and even through the pipes feeding our washer in the laundry room. Mind you these locations are all 10-20 feet apart.
He's sprayed the bathroom and laundry room pipes inside the wall with Termidor, and I've sprayed around the toilet with Ortho Home Defense, but given there's obviously a colony of ants under the house and we have a concrete slab what recourse do we have short of drilling holes in the concrete, which even that is a crap shoot since we have no idea where the colony is.
The bug guy said Termidor should in time work, hopefully within 3 weeks to 3 months, which it's been alittle over a month since he sprayed the first time, but I'm afraid that might not be enough. There are literally zero ants in the yard, so they are sustaining themselves on whatever's under the house, which it's only 7 months old so there can't be much.
So are we just destined to have ants from now on? Am I not giving Termidor enough time to work? I've not read one case where it didn't work, but with a baby and toddler I really can't afford to wait too long. The bug guy has done a great job trying to fight back, but he said he's even dumbfounded as to why they're being so aggressive since it seems that we're doing a great job cutting off their food source. Is our case just that unique?
Anyway, thanks for any advice anyone has.
