Here in Florida we have Palmetto bugs -- giant roaches. Does anyone know if bugs can get in through central air conditioners? Everything else seems to be sealed off, including roof vents.
Roaches that's pretty bad. I have a major health issue in my home from my husband and step son smoking in the garage (they are both heavy smokers) The smoke smell is coming I'm to the house through the room vents. So bad that if my 25 year old stepson comes home late (4:00am) and has a cigarette it wakes me up in my bedroom at the opposite side of the house.
They both say I am crazy and we argue about it all the time. They refuse to smoke outside when it is cold out. My son does not smoke and he says he can smell it too. I also worry about the second hand smoke and how it will affect our two parrots as their lungs are very efficient. Can anyone tell me why and how this is getting into the vents?
Usually no----the air currents alone will discourage them but if there is a break in the system it could be possible. Roaches are VERY adept at slipping thru the tinest cracks and into your home--plus many species fly very well so an open door or window is like a super highway--also the large American & Australian roaches can scoot down your bathroom vent pipe and navigate through some water and plumbing and show up in your bathroom..make sure you screen that little pipe. check out my little hint site for more info-I try to update it often
Yes or they could be coming up through shower/sink drains, around where your water lines come into the house, underneath a closed door, etc. We deal with them here in New Mexico also, mainly during Spring and Summer when we start watering our lawn outdoors more regularly. Their appearance is not a sign of unclean conditions like their smaller cousin (food roach), but an attraction to moist or humid conditions.
We use Boric Acid for this type of roach. We live in eastern Ga were we get of these. Be sure to put it around the unit and not were the air flows. Make sure the air is off so it won't blow in your eyes or face. We also put it around the doors as these roaches can come in very small places and they can fly also. Triming bushes around your house will cut down on the roaches also.
I live in Louisiana and we also have the same bugs. They seem to be able to slip in with absolutely minimal space available, so I'm sure they can get in through an AC unit. Spray heavily around your unit (not into it). Be sure it is not about to rain. I would also spray inside and outside of all windows and doors. I've seen them slip under a door. They are hard to erradicate, so good luck.
