Good morning y'all,

I have a greenhouse that is sat on some concrete tiles, with no water inside. I use it in the winters, but it is summer here now so no plants/trees are housed inside.

But I have a little infestation.

I was thinking of going to Home Depot and buying one of those insect pest smoke grenade thingamajigs. My only concern is if one of those will leave residue inside my greenhouse.

Also want to know so I can prevent future outbreaks.
