Does as the posts said

This is super since it us safe around child and animals. Kills right away. Thank God no more ants. If we see one we spray the area again and their going. Also killes crickets and spiders, Besides the nats and fruits flys. I take a disposable container and take a paper towel or babywipe and put a piece of food on it then spray the paper towels or wipes with the bug spray then throw it away. Works amazing and doesn't stink as bad as other sprays. Prayer and God's blessings to everyone and your families

spray nozzle doesn't clog

Switched from the other well known spider spray because the nozzle would clog and I would end up throwing the spray can away. Haven't had this problem yet with the dog safe spider spray. Will continue to buy this spray because it kills the spider's and smells ok.

I like that I can use this in the house without harm to my animals or myself. One application and no more ants. Do not use on plants. I killed a patch of grass when spraying outside the home and targeted a large mound of ants. Smell fades after two days and no more ants.
