How do I get the pheromones?

So I just killed the fire ant queen and she gave me some pheromones and I think she gave me enough for the armor set but I had to make some lint rope so while I was waiting I went down to the oak lab then I came back and I didn't have any pheromones so how do I get more or if yall want yall can just tell me the set bonus for the fire ant queen armor
