The deadly spray icon is a bottle with a lid on the top. On the bottle there will be a circle and inside the circle there is a diagonal line to show it should not be used. The top of the cap there are little dots coming out to show that there are particles coming out of the bottle.
This is a Insecticide icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,300 icons, all in the same style and quality.
