yeah, this is what i was worried about: i've seen a few baby roaches (a few mm in length) this morning. the eggs must have been underneath the counter or something - somewhere i can't get to. but they're all dead. the residues seem to have got 'em.
they usually hatch in the fall, so this is actually a bit early. maybe it's the weather. the fucking polar vortex is back and it's getting us some cool nights in the low teens.
the fact that i'm not seeing any adults suggests to me that any oothecae that were left have been stranded, in terms of a nesting population. and the fact that they're coming out for food and getting poisoned suggests that they have to. something i noticed before the centipedes left is that they were moving back to the kitchen, indicating they sensed food (ie roaches) there. a few of them were also killed by the poison (although i've seen several in the back room so the population there is doing fine).
if anything, the early hatch is probably beneficial to me as it gets rid of them while the residues are still there. i think i'm still winning. i was never certain if they were coming in from out of the apartment or coming up from under the floors; i was fairly sure of the former, but it meant i had to stop them before they started leaving eggs under the cabinets. i do think they were mostly coming in from outside, but i didn't get to them before at least a few eggs got laid.
now, i simply don't know how many eggs are under there....and have to hope the poison holds out long enough to get them before they breed another time....
if i start noticing a larger population, the next step will be finding out what hole in the floor they're coming up and steel wooling it.
i can't hope to bait them because the truth is that the whole neighbourhood is infested. they'll come back. i just have to block entry.
i'm not happy about spraying again, either. the pesticide i'm using is supposed to have extremely low mammal toxicity, i did the research and it's supposed to be safe for humans in non-ridiculous direct dosages (meaning don't drink it), but i'm a little concerned that it might have something to do with my sore neck.
