I have to 'fumigate' two houses occupied until recently by elderly people with flea ridden cats. After several weeks of non-occupation I assumed it was safe to enter but I still get bites on my legs and I gather this will continue as my footsteps disturb the fleas and 'activate' the eggs/larvae/pupa. I've done the usual Google and it's all very interesting reading!
Can anyone suggest where I can buy the supplies to fumigate the houses myself please? Whatever I get needs to have a 'residual' effect to eliminate future hatchings. Or am I right in thinking one can no longer get these sort of chemicals and I have no choice but to bring in the pest control experts and pay the bill?
The only thing I can get is a sulphur candle from the garden centres but I doubt that will be very effective. I have face masks, pressurised mask, protection suit, long gloves.
many thanks
