Don't rely on the Heimish for infestation issues.
We have seen that some Heimish hashgochas has a complete lack of knowledge in infestation. Refusing to accept responsibility for certifying infested product.
Heimish certifiers certify Bodek products even though there is an infestation issue. They will certify product that contains insects even up to & including 1.3 mm in size. Note: the series numbers on a dollar bill are only 1 mm and it's clearly visible.
The heimish hashgochas in Brooklyn, on catering halls, restaurants, takeout, etc also have a lack of properly tested & trained Mashgichim. It's advisable to refrain from consuming any items that require bedika, unless the mashgiach is certified from a reliable agency in bedikas tolay'im.
