Doe this oroduct work for bedbugs?

Yes it does, however it's illegal to use indoors. There's scientific evidence that malathion poses virtually no risk to people when used properly. However, due to current laws in the US nobody is going to tell you to use it indoors.

What percent malathion?

50% Malathion and 50% other ingredients

anyone know what the mixture is per gallon?

it really depends upon the target insect and the plants. We use it for Mosquito control and use 10 tsp per gallon around would shrubs and grasses. If we were using in on our roses or other ornamentals we would dilute it to 2 tsp per gallon. It is a powerful insect killer but it can be very damaging to the plants and the environment if over used.

Does this leave a residue that keeps on killing insects?

Malathion IS residual, and will last from 2 to 10 days, depending on weather conditions. It's extremely lethal to honeybees, so take care not to use it where honeybees may feed.
