Only has a 2 week residual and I had to re-apply every 2 weeks for my customer. Not near as effective as bifienthrin. Oil based and ruined my rubber gaskets in my Stihl sr 450. Chemical tank and hose had a thick oil coating on it and took me hours to clean. Bought 2 bottles and will be sending the unopened one back.
used EcoVia on my lake house for spiders. Used hose-end sprayer set for 4oz per gallon. Didn't seem to kill spiders and definitely did not repel spiders after the fact. I noticed a big juicy spider while I was spraying - 5 hours later it was very much alive. We have a lot of windows and this stuff made cleaning the windows more difficult.
Sprayed outside the house and some trees. Ants came back in droves after three days using the same ant routes they used before. Not impressed at all with this product. Not only expensive but ineffective to use as far as I am concerned.
Have tried EcoVia MT and have had good results 5 Stars however Tried the EC because it offers protection against other insects not listed on MT and found many complaints about the lack of effectiveness especially concerning mosquitoes and ticks going by all the negative feedback I give EC a Minus 5 very disappointing not in business to lose money or get negative feedback .
