From the Wikipedia article on Chametz (leaven):
The Torah has several commandments governing chametz during Passover:
The positive commandment to remove all chametz from one's home (Exodus 12:15).
Not to possess chametz in one's domain. (Exodus 12:19, Deuteronomy 16:4).
Not to eat chametz, or mixtures containing chametz (Exodus 13:3, Exodus ...

Kaf Hachaim, 664:60, tells us what to do with the lulav and esrog after Hoshanah Rabbah (the last time we use the lulav), as well as the aravos used for hosha'anas. I'm translating this from the hebrew, so I may have gotten some of the details wrong. Please correct me if I got something wrong:
After prayer on Hoshana Rabbah take the lulav (with hadasim and ...

Hacham Ovadia Yosef discusses this issue in Yabia Omer Helek 7 Siman 44 in terms of the kinneret, which supplies water for most of israel. Kibbutzim along the coast are KNOWN for dumping hametz into the water. He answers that hametz dumped before pesach is nullified in 60. During pesach, he applies the concept of "tzonen bitzonen". Since the hametz and water ...

Rav Yosef Tzvi Rimon indicates (article) that the forgotten pieces would be nullified by bitul chametz.
the pieces should be smaller than a ke-zayit, so that if one of them is not found, the bittul declaration will suffice to avoid the violation.

Chametz is prohibited to eat or own on Passover, and this includes any flour made of the five grains that has come into contact with water for enough time to halachically ferment, which is a period of at least 18 minutes.
Se'or, which is the heavily-leavened sourdough that was commonly used as a leavening agent, is also prohibitted to eat or own on ...

Strictly speaking, if one has 10 pieces of chametz and finds only 9 of them, one must look for the missing piece.
(If you are sure that you found 9 out of the original 10, you need to look for the missing piece. But if what you found might not be what you set out, you need to look for all 10.)
These laws are detailed in Orach Chayyim 439. For example, ...

R' Shneur Zalman of Liadi writes (Orach Chaim 467:48):
מי שרוצה לשאוב בפסח מבארות של נכרים או
מבארות של ישראל שלא נזהר בהן מחמץ כל
השנה, טוב שיסנן המים בבגד נקי בכל פעם
ששואב. אבל מעיקר הדין אין מחזיקין
איסור מספק.

from wells owned by non-Jews, or by
Jews but with which they weren't

Ultimately the source is from the Talmud:
Rabbis Ami and Asi would make a meal of the bread that was used for an eiruv, stating since it was used for one mitzva, let us use it for another (Talmud Shabbos 117b).
Rema (664:9) we put away aravoth and use them to bake matzo, for the reason aforementioned.
Since matzo baking has been commercialized, the custom ...

The easiest thing to do would be to contact a kashrut supervising agency and they would be able to answer, item by item. They may, though, not want to give rulings on individual products if the overall storefront is not kosher for passover or using their general supervision services. Some groups, like the OU had a hotline available in the days before ...

A few reasons that come to mind:
The taam of chametz may be absorbed in the utensils used to manufacture that product, and likely there will not be shishim to nullify that taam.
There may be minuscule amounts of chametz that need not be listed on the label or are included in the generic "natural/artificial flavors", but which are significant due to their ...

This list from the Star-K has many items that you can feed your cat on Pesach.
Per the CRC-Chicago
Kitniyot ingredients, such as corn and rice, are acceptable in pet
foods for Passover, because while Ashkenazim do not customarily eat
kitniyot, they are permitted to own and benefit from them.

In OC 471 sk 12, the Mishna Berurah mentions that certain types of matza which we are only machmir to treat as chametz (eg matza that folded over itself in the oven) are forbidden to be eaten on Erev Pesach as they are actually kosher matza according to the basic law. The assumption of this point is that had they actually been chametz, they would have been ...

Rabbi Shlomo Zalman Auerbach ruled that while yes, we say "chametz is not nullified even 1/1000", but a few pieces of bread in the ocean are so far past the mark that they become nullified. So somewhere between one-in-a-thousand and one-in-a-quintillion (approximate volume of the Mediterranean in gallons).

The Shulchan Aruch (OC 433:10) rules that synagogues need to be checked for chametz prior to pesach as children sometimes bring in chametz.
The Mishna Berura there implies the obligation to check is on the "shamashim" (sextons) of the synagogues. He further notes that the sextons do not need to recite the nullification over the chametz in the synagogue as ...

My Pardes teacher Zvi Wolf warned us to be very careful when spreading around chametz just to "find" it. Specifically, be careful to not leave any chametz in your nice clean rooms. Eg crumbs from bread, etc.
If you do it, don't overdo it. And think about the crumbs in advance. Eg one slice of bread in a bag--find the bag with chametz in it, not the chametz ...

You wanted to know, why some people might be machmir on this:
From InstituteforDayanim.com
Kashering a microwave for Pesach is impossible since only metal or wood can be kashered for Pesach. Although one can kasher plastic the rest of the year, one should not do so for Pesach. The inside of a microwave is generally not metal and is thus not kasherable.

Chazal obligated each person to search
for Chometz on the night before
Pesach. [If one leaves town before
that time, he is still obligated to
search for Chometz the night before he
leaves, although no blessing is
recited for that search.] In the
opinion of many Poskim, the ...

The Mishna in Pesachim 2:1 records a dispute as to how Biur Chametz is to be done. Rabbi Yehuda, comparing the destruction of Chametz to the destruction of invalid Korbanot, rules that Chametz must be destroyed by burning. The Chachamim there argue and rule that any form of destruction (tossing into the sea, or crumbling it into the wind) is acceptable. The ...

Like any fruit, wheat can have different varieties. Just because it is larger or slightly easier to digest does not make it something else other than wheat. It grows the same way, it is harvested much the same way, it is ground to flour, and it is used for bread. While it's conceivable that the 18-minute rule for Matzah might need to be adjusted because of ...

Obviously, we're not going to find the word "khorasan" anywhere in the classic literature, so the best I can do for a proof that's based on sources more than 25 years old will have to utilize some indirect evidence.
I figure, if these two types of dagan (grain) aren't kilayim with each other:
than certainly these two aren't! I bet you can't even tell ...

The Shulchan Aruch (OC 555:3) rules that if one kneaded his dough with hot water it is forbidden, the assumption being that heat makes something become chametz quicker. This is also seen in the rule (559:1) not to knead the dough in the sun or in a room with a hot oven. Moreover one can leave dough in cold water indefinitely to prevent its becoming chametz ...

Many are stringent regarding various ingredients that go into the pill, and this is a popular and well-established custom.
Nonetheless, the Chicago Rabbinical Council policy still holds:
FOR LAWS OF TAKING MEDICINE ON SHABBOS AND YOMTOV, PLEASE CONSULT YOUR RABBI.
All pill medication -- with or without chametz -- that one swallows is permitted. ...

It's customary to appoint the rabbi your agent to do effect the sale using a belt-and-suspenders approach: a signed contract, an oral authorization, and a sudar. Is it necessary? No, which is why some respectable rabbis accept agency via the Internet. But it's customary. And sudar (and possibly a signed contract, too) is only done in person, not online.

Typically, your rabbi will ask you and remind you to sell Chametz at your workplace.
If, however, this slipped past you and you remembered (before noon on) Erev Pesach but it was too late to find your rabbi to sign a contract, you could gather two male Jewish witnesses and tell them that all of your chametz belongs to John Doe (pick a non-Jew who you know), ...

While the basic law is that the lulav was already used for its mitzva (and isn't otherwise holy) and can be thrown away, people like to use it for some other mitzva. So if you can use it to serve as fuel and help burn chametz, that's a great use. (If you can think of some other mitzva way to dispose of the lulav earlier that would work too, but chametz is ...

True, but at this point the item deposited with you is going to cause you harm (because you'll be violating the mitzvos of בל יראה ובל ימצא). So, logically, you should be allowed to get rid of it.
A possibly analogous case is in Shulchan Aruch, Choshen Mishpat 292:8, where a person who is holding money or valuables for someone else is threatened by thieves, ...
