Ironman verdict
Red spiders' eggs is a free-to-play item. Other players trade it, but an Ironman cannot use the Grand Exchange or trade, so you get your own. We list 8 monsters and 2 other sources for it.
The lowest-level monster that drops it is Cave bug (level 6), at 2/128, about one in 64 kills. The best rate is from Spidine (level 42): Always, 3–6 at a time. The 8 monsters we list with a combat level range from level 6 to 890. 4 monsters drop it already noted, including Venenatis and Spindel, which saves inventory space on a trip. It also comes from 2 other sources, such as Chest (Rogues' Castle) and Giant egg sac.
Bosses we cover that drop it: Venenatis, Spindel and Araxxor.
It is a material in 4 recipes, for example Strength potion(4), Restore potion(3) (22 Herblore) and Super restore(3) (63 Herblore). High Alchemy (55 Magic) turns one into 4 coins. Each cast uses a nature rune, 180 coins from a rune shop, and five fire runes that a fire staff replaces, so an alch loses about 176 coins; only alch it to clear space.
