Great photography. Congrats on finding something that worked too.

I love those old ones, I always feel for the Japanese guy in the hot rubber suit. The wires were awesome for King Ghidorah!

Gerardo, I am a little concerned about Deltamethrin, the label says DO NOT APPLY TO PLANTS USED AS FOOD SOURCES. I saw something similar on every brand that showed when I googled it. The warning also said not safe for human consumption.

I suspect it's related to differing restrictions on pyrethroid use in US vs MX. The main usage is principally cotton, but also coffee, corn, tobacco, rice, wheat, fava, soy, fruits/vegetables (cabbage, tomato, cucurbits/melons).

I read a WHO report on deltamethrin where they reported 90% degradation in a greenhouse setting by week 4. With my sun conditions, degradation will be much faster. And since I'm not eating anything for at least a month, I figure it'll be safe.

This is verbatim from http://npic.orst.edu/factsheets/Deltatech.pdf
"Plants
• The half-life of deltamethrin on vegetative surfaces ranges from 5.9-17.0 days, depending on the plant species.
• Deltamethrin is not likely to adsorb as strongly to leafy components of vegetation, so volatilization from these surfaces may be higher compared to soil. In one field study, 12-72% of deltamethrin volatilized from plant leaves 24 hours after application, depending on the plant species.
• Deltamethrin is unlikely to be taken up by terrestrial plants due to its tendency to bind to soils and rapid degradation.
Uptake
was not observed through leaves or roots of most plants and therefore it is considered a non-systemic compound."
