Not impressed
By Trena on 05/03/2019
Bees die on contact but doesn't last on spraying...a few hours and the bees are back at boring. 24 gallons later and still just as many bees. Not overly impressed with this chemical. I can not stand outside and shoot them with this so for a continuous spray it is worthless.

Still have spiders.

I sprayed per label. Killed spiders and fire ants on contact but no residual like the website says. I've sprayed twice in 3 weeks. Once double rate. Whatever insect doesn't get actually sprayed doesn't die. I have as many spiders now as I did before I sprayed. Very disappointed.
not as good as they say

bought this and sprayed a day after receiving it, I think the bugs thought it was food. the next day they were still hanging around, a week later started seeing the same bugs as before-still alive but they must have called their Wolf spider friends--. going to try something else, save your money, dont buy this product
Expert response:
While Demon Max can have some knock down properties, it is not considered a contact kill product. It is a residual insecticide that once dry will last on the surface 3-6 months indoors (although you would respray more frequently for an active infestation) and 30-60 days outdoors depending on how the elements effect it over time. Spiders are harder to kill as they do not groom themselves and have long legs that keep their bodies off the ground but as long as they contact a treated area long enough they will die it does just take time.
