insecticide

We use Ammo sometimes on the farm and I think it is 30% active ingredient compared to 25% for Viper. Just according to what pyrethroids you can get cheapest but be sure to look at active ingredient percentage.

this is good info. im only replying so i can find it later

Tempo is great too. Long residual. Not only spiders, etc. but dirt daubers will not build nest where it's sprayed.

I thought that only came in granular. Or is it something else?

I live in the sticks. For years I sprayed outside around the house. All I was doing was killing off the lizards and frogs and kept fighting spiders. After talking to a few people, they told me to give it a year or two without spraying and let things happen. After the first year, I saw less bugs around the house. By the second year, I had a shite load of lizards and frogs around the house and no bugs. Only problem is that they get into the house at times.
