When DDT binds to a sodium ion channel, the channel remains open all the time. Suggest how DDT kills insects

After an action potential has been generated due to rapid depolarisation the sodium ion channels close and the potassium ion channels open so that the nerve cell can repolarise. However, if the sodium ion channels stay open, the nerve cell can't repolarise and that means it will no longer be able to generate action potentials. This will stop nervous communication in the insect so it will die.
