Have been using Tempo inside and outside of house. Have also used bifen and lambda cy outside of house. After spraying 10 times during the last 18 months, Wife still finds some in the house, but seems to be less of them.

Before living in this house I did not know that there is scorpions in Kansas. Parents live less then 1 mile away and have not seen a scorpion there in 15 years. Last year the sticky traps in the shed at my house caught about 20 scorpions. If you want to find them it is somewhat easy to find them in the pasture under the rocks near my house. I think that sticky traps are about as good as the chemicals in controlling them and also provide a way to monitor the population.
