High temperatures degrade capsaicin in chilli peppers, right?

Stronger spray

If the first recipe is not strong enough for you then you need to pull out the big guns. Start by getting pure alcohol. Pour crushed chilli peppers (you can also use fresh chillies) into a container and add alcohol and let it infuse for one day at least. We recommend three days . A good idea is to prepare it ahead of time so you have it ready when needed.

Strain and mix with water in a ratio of 1:1. Apply as neededand be careful, as this stuff is really powerful. Do not spray during hot summer days, as you can damage your plants. A cloudy morning or evening is best.
