sorry need to update. just called Truly Care. they say me seeing 1 or 2 might still be normal, as they might have come in from places, but if there is a persistent problem, then I should consider doing a contract based (buy a few times services). coz my one time service last time was not guaranteed.. i was like huh? if I still have problems, and i have to pay for you multiple times to come back, doesn't that mean the pesticides are not working?
we got rid of all the insects last time my provide came one time, at least for a month or 2. ok, I agree 1 or 2 might be a coincidence, but why would I still use them if i keep having persistent problem. so they seem to be priced cheaper, but effect seems to be comparable to the price. I'll hold out for another month or so to see what happens. We don't have a huge cockcroach/insect problem, so it's really difficult to tell what's working and what's not, but one or two here and there is really annoying.
