Spraying tonight

I have various insects that somehow found my garden even though I've never had one before. Some of them make just unsightly holes some have the potential to undo all my work. So, I'm spraying malathion on anything that seems affected. Rule #1 is never spray above 80f because heat+sun+ chemical= ozone gas that damages plants. Malathion- it's been on the market for decades and I've never heard anything bad about it when used as I'm about to (lobster die off 15 years ago is another story when the state was controlling West Nile virus). Now I will have to wash my food before eating but it's better than having everything destroyed.
