Try freezing first. That's completely safe for you and will kill most subjects without altering their colors or structures. Some are freeze resistant and need lower temperatures and/or longer exposure. Condensation will be an issue. Be sure to let your subjects sit long enough to dry off after coming out of the freezer, unless of course you want that appearance of dewdrops.

CO2 (carbon dioxide) will anesthetize some species, but there are wide variations in its effectiveness.

If you want chemical killing agents, there's a wide variety. Ethyl acetate is one that's commonly used, works quickly, and is pretty safe for humans. But you can't buy it at the corner drug or hardware store. Acetone works, as does lighter fluid. There's a tendency for chemical agents to make specimens stiff and hard to work with.

Try freezing first.

The standard for butterflies in the old days, when collecting was respectable, was cyanide. An available source of hydrogen cyanide is by crushing the leaves of cherry laurel inside a glass jar, etc. The moisture also keeps the dead insects "relaxed".

If using ethyl acetate beware of use in a confined space as the fumes are quite intoxicating.
