Spectracide diazinon is a pesticide that combats ants, grubs, spiders and many other insects. It comes in a concentrate, which means it must be mixed with water before you apply it to your lawn. Another important thing to remember when using spectracide diazinon is that it is poisonous. Always keep children and pets indoors while you prepare and use the spectracide diazinon.
Put on a pair of gloves and a mask before you open your spectracide diazinon.
Pour 5 tbsp. of spectracide diazinon into a garden sprayer.
Add 1 gallon of water. As it pours in, it will naturally mix with the spectracide diazinon. If you feel the need to mix it yourself, use a wooden mixing stick like you would use to mix paint with.
Place the lid on the garden sprayer and use it on your lawn where you are having a problem with insects.
