The roaches laid eggs before the sharp sand killed them. Eventually they hatched. If you can kill them all before they get old enough to lay eggs, they will eventually disappear. Is diatomaceous earth very effective against roaches?
Should I reapply the powder and wait it out?
Yeah, if the new ones are little ones and you don't see any big ones, then just reapply the powder. Usually getting rid of roaches takes weeks because you have to get all the eggs you can't reach with cleaning (I would use poison myself, but that won't get into walls either, so you have to wait for the babies to hatch out, either way). If you're still seeing big roaches, then the powder isn't working, or they are coming from someplace else, like a neighbor's apartment.
PB, I can still remember when I had first moved to San Francisco and somehow a woman on the bus and I got onto the topic of roaches.
jkgrandma, that tactic will actually work on rats and sea gulls. Neither of those animals can burp, oddly enough, considering what they eat. If you can trick them into eating an alka-seltzer it's over for them. I'm not sure which meaning you are giving "soda". It could be either a carbonated beverage, or baking soda. I know that spreading borax/boric acid powder around is highly toxic to roaches and fairly benign to people (do you remember Twenty Mule Team Borax?).
I only had them once in Kentucky when I moved into a rental house. It was fairly easy to get rid of them, though it takes weeks to do, but keeping them from coming back from someplace else is the hard part. The whole building has to be cleared of them, inside and outside. They aren't too fussy about where they live or lay their eggs, and I have seen them take up residence in cars in the south.
One of the blessings of winter is that we have very few pests and those are fairly easy to manage if they bother you.
The ideal situation for you here is to use gencore or gentrol. Gentrol keeps the roach from molting into the adult (egg laying) stage. Thus the eggs are never formed and it is now much easier to kill those roaches and eggs are not a concern.
Hope that helps some!
Have a pest free day!
