Bonide Propane Insect Fogger – Outdoor Pest Control for Mosquitoes, Flies & Bugs – Ideal for Backyards, Gardens & Camping

This is the 2nd time purchasing this same item. I left the first one out in the yard, under the covered patio but that still allowed it to get too dusty and it stopped working.The second one, I had to leave it "soaking" in the insecticide liquid for at least 24-48 hours before it started working. But once it gets going, it's a powerful fogger and it works great.
