what type of pets do you have?
how long have you had this problem?
I am so very sorry you had to wait for an answer. Your question get moved out of "pets" and into the "general" category - which I do not have a profile for - so I could not answer you. Mgmnt has been so kind to send it back to pets so now I am happy to help you.
The reason this is happening is because tiny fly eggs get indoors (perhaps on the dogs feet). These hatch into maggots (fly larva) - very teeny and hard to see. These, in turn become those nasty obnoxious flies.
You can avoid this in the future by wiping the dogs feet with fly wipes (pet supply) when they come in. Aslo if you have an invasion, you can use a one time bomb or diffuser. The only positive thing is that the annoying pests only each live a day or two but of course new ones hatch and begin the cycle over again.
Please let me know if you still have questions. I am happy to help.
First, let me appologize. I do not know why you are ahving so much difficulty in getting through but I do sincerely XXXXX XXXXX this problem.
To answer your question, many people do have simialar issues with flies. All you need is one to have gotten in while the renovations were being done to have an epidemic because they lay thousands of eggs. They can also breed inside walls.
The best way to get rid of that at this point is to have a service come in that removes the switchplates and sprays the spaces in between the walls and distroys the nests. Then you should be rid of them once and for all.
If you have any more questions and cannot get through just send me a private message and I will be more then happy to help you.
