No, the cutlery is not silver. The numbers 90 and 30 are likely to indicate that the cutlery is made of stainless steel, as these numbers are commonly used to denote the percentage of stainless steel in the alloy. Silver cutlery would typically be marked with a sterling silver hallmark, such as "925" or "sterling." Therefore, the presence of the numbers 90 and 30 suggests that the cutlery is not made of silver. **

The value of a 150-piece silver cutlery set can vary greatly depending on a number of factors, including the quality and purity of the silver, the brand or maker, the age and condition of the set, and current market demand. In general, a high-quality 150-piece silver cutlery set could be worth thousands of dollars, especially if it is an antique or from a prestigious maker. However, a set made from lower-quality silver or in poor condition may be worth significantly less. It is best to have the set appraised by a professional to determine its true value. **

The value of a 12-piece silver cutlery set can vary widely depending on factors such as the quality of the silver, the brand, and the design. However, on average, a 12-piece silver cutlery set can be worth anywhere from $200 to $800 or more. Antique or rare sets may be worth even more, while sets made from lower quality silver may be worth less. It's best to have the set appraised by a professional to get an accurate value. **

A moth is a type of insect that is often referred to as a "night butterfly" due to its similar appearance and behavior to butterflies. Moths are known for being active at night and are attracted to light sources. They have a similar life cycle to butterflies, going through stages of egg, larva (caterpillar), pupa, and adult. Moths come in a wide variety of shapes, sizes, and colors, and can be found in diverse habitats around the world. **

Insect spray is designed to be applied to surfaces to repel insects, so it can stay on cutlery and other items if it is sprayed directly onto them. However, it is not recommended to spray insect spray directly onto items that come into contact with food, as the chemicals in the spray can be harmful if ingested. It is best to wash cutlery and other items that have come into contact with insect spray before using them for food preparation or consumption. **

Insect spray typically does not remain on cutlery or other surfaces after it has been used. Most insect sprays are designed to quickly evaporate after application, leaving no residue behind. However, it is always a good idea to wash any items that may have come into contact with insect spray before using them for food preparation or consumption, just to be safe. **

It is likely that a moth is in the room. Moths are typically more active at night and are attracted to light sources, which may lead them into indoor spaces. Night butterflies, on the other hand, are not a commonly recognized type of insect and are not typically found indoors. Therefore, the insect in the room is more likely to be a moth. **
