Spider Black Brown Widows Southern Cal area

Hi I am a newbie to Parrot Forum
Spiders!!! Brown Widows!!
In my Aviary!!!!!
Found a few in late July, groomed and power washed entire Aviary.
This morning I found two huge nest sacs in Aviary opposite corners, 10 plus in one corner and 8 spiky egg sacs in another.... I know they are brown or black widows because I squished a few live ones after I rolled them around (I water boarded them 1st)

I have an outdoor Aviary for my Cockatoos, Benjie a 21 yr old Umbrella... And his "girlfriend" Cherub, a rescue Monacan... Molls an, darn spell check sorry it's late... Big peachy highlighted cockatoo.
Cherub's owner died... And Benjie has bonded with her.... When I am not there he is happy to preen her and do his mating call behavior...

I am taking them to Bird Farm Tuesday am till I get their Aviary tented or treated by professionals pest control company

Any suggestions for pesticide and company for monthly maintenance is much appreciated.

I use power washer vinegar for cleaning
Chinese chrysanthemum chalk around outside for ants ....

Diatomaceous earth kills anything with an exoskeleton. I have an outdoor aviary with finches so I researched for a good while how best to keep ants away, and this was the best solution. It doesn't work once it gets wet though.
