I have a kitten but I went out of town and my parents kept it at their house. When I got home I was swarmed with fleas. I have fogged my house three times and there seems to be less but they are still there. I don't what else to do besides hire a professional but I don't have the money to pay one. I also understand I need to spray outside but it continues to rain.
I bought foggers for fleas from a local vet that solved my infestation in a very old house. They worked great. Sorry it was so long ago I don't know the chemical or brand. But the trick, according to the vet is the timing and to bomb the house twice. It MUST be done between 10 and 12 days apart to be effective. That allows time for all the eggs to hatch and before they can reproduce at 14 days or so. Bomb the second time too soon and eggs will hatch and reinfect. Bomb too late and the hatched fleas will lay more eggs and you are back to where you were. That worked for me. Good Luck PS, that 100 year old house had a spider problem as well and I didn't see a spider for a year after using those bombs.
Who told you outside needed doing? That's wrong. You need to get a household flea spray with IGR (insect growth regulator) this makes all adult fleas unable to lay eggs and makes the eggs that are there infertile so this breaks the cycle and kills them all with no way of return, the cat also needs treating, first with flea powder or Pet flea spray for cats then when that's done, use a flea spot on repellant, this protects from fleas for a month then it's safe to 're apply if needed. I had this problem n that's what I did now we have been flea free for 2 years, I have 3 dogs and 3 cats so I know it defo works. The household flea spray I used is called johnsons veterinary 4 fleas household spray extra guard and it protects for 6 months.
You need to treat the kitten with Frontline or what ever your vet recommends. Use a vet approve spot on treatment every month from now on. This will help resolve your current problem and prevent future infestations. You have to vacuum everyday for several weeks and fog again after a few days as needed. It can take several weeks to resolve a bad flea infestation. There are four stages of fleas in your carpet. Eggs, Larvae, Pupae, and Adult. The foggers only works on eggs, larvae and adult. The pupae is the hardest stage to kill. The fleas are in a protective cocoon and pesticide does not bother them. They will wait inside the cocoon for months until they sense vibration and heat which tells them a food source is near by (you). By vacuuming everyday you create vibration and heat in the room. This causes them to hatch out an be exposed to the pesticide residue left by your fogging. Instead of fogging you might consider just using a can of flea spray that you manually spray on the carpet. You can then target hard to get areas like under the bed or furniture that the fog might not get to. You can also avoid areas like your clothes and dishes that you might not want to get pesticide all over. Just be sure it is labeled as a flea spray that kills fleas and eggs.
