Re: OT - exterminator
If you want an inexpensive DYI, then go to home depot and buy the spray defoggers that make you leave your house for 2 hours. You need one for each room. Cats must leave house. In addition, if it's in the fish tank room, just cover it with a drop cloth. Also open windows for the suggested time frame on package.
This is very cheap. After you are done, places like the the kitchen counters have to be wiped clean and the floors would also have to be done. So there is work to do, however, you will save a fortune.
Sometimes, if the animals bring the stuff in from the yard, you may have to do it again, if the problem re-enters.
Obviously, you also should wash your animals in a bath.
You can also spot spray with stuff in all of the corners of the house. This is good, on pests that are not everywhere. I usually, try this first and only go to the whole house defogger when that does not work.
Hope this helps.
