I have a problem with spiders...
I like Garden spiders, and I don't mind wolf spiders, but they don't come into the house.
My problem is with poisonous ones though... There are brown recluse spiders all over my house... Luckily, I don't have such a bad reaction as most people have...They can't bite through people's skin unless they have pressure put on their fangs, so we haven't had any calamities. My kids haven't been bit, but I try to always do an inspection of their bedrooms before they lay down... We live pretty minimalistic, so it isn't hard to do.
In the Fall, we usually find a couple black widows on our property...
We have had the house sprayed, and they were still an issue...
I have packed away my extensive book collection, eliminated allot of furniture, sealed up any cracks and holes I can find in my walls, floors, and ceilings... But they are still EVERYWHERE!...
I turn my furniture over every week, and vacuum the cushions, crevasses, and undersides of everything... I usually find an egg sack somewhere every week... I have ripped all of the dust barriers off of the back of mirrors and undersides of furniture, and from the bottoms of my box-springs of my beds... When I initially did this, it eliminated the biggest part of my infestation...
Now, I only find them in the very few places I cannot easily get to every week, and as long as I still make it a point to regularly clean those areas, the main living space is safe...
I hope you get it figured out.
