Spray | Ant Killer Indoor & Outdoor 250ml Aerosol | Insect Killer Indoor & Outdoor Use – Insecticide Bug Spray Lacquer - Effective for Ants, Cockroach, Woodlice, & Other Crawling Insects

This is the best stuff. Thank goodness it is back in stock. We have a problem with flies living in the double glazing frames. A good spray of this all round keeps them away for six months or more. Flies just don`t come back. Highly recommended. Would also work for other flying bugs.

Used this product for years now to spray windows and doors to deter Spiders, works a treat! Used to be easy to get hold off on stores like B&Q however it seems to have disappeared from shops now but was rElieved to find it available from this seller on Amazon and although the price has increased from what I used to be able to get it for its still worth it for a house full of arachnophobes and with free delivery I was happy :) of you have white uPVC it will stain it eventually I tend to try and stick to the inside of the frame, but with a bit of elbow grease the stains do come off but obviously y then the product is gone so tend to wait till after spider season to clean off properly. Normal window cleaning does not effect the product it lasts a few months I tend to respray every 2-3 months. Arrived on time with full tracking right up to the knock on the door :)

Arrived very quickly, very good against ants, and value for money.

Brilliant, no further snt problems

I have used Deathlac for many years but recently it doesn't seem as potent as it was. Perhaps a change of formula?It's a lacquer based spray that does keep working for a long time. It can be sprayed on walls or steps to deter ants from entering the property. Much better than the powder alternative.

It started with a couple of ants...Found in my conservatory, a spray outside of a 'similar' product, appeared to do the job...Or so I thought.A few days later there were more ants, so I used caulk to seal the gap between laminate floor and skirting board trim, this appeared to do nothing other than give the ants an excuse to find any possible gap that was left in the vicinity, which they did, including 1 super-ant who appeared to break through caulk (he must have had his weetabix).In tribute to that particular ant, I let him escape outside, a mark of respect for what he had done, with a warning that a re-appearance would not be tolerated, I would assume he heeded the warning, if he did not and was caught in the battle mentioned below, RIP super-ant.Basically, caulking the gaps was not working, so much so, that they ended up coming through under the door between lounge and conservatory, which was a total pain, this was now time for a proper battleplan.Stage 1 = This involved lifting up the carpet in the lounge, and placing small amounts of ant-powder all across the edges, followed by a spray of 'Dethlac' a double solution you could say. Basically any point they were getting in there from, was blocked with powder and spray. Put the carpet back down (gently, so as not to get a cloud of ant powder in your face)That ended their advance into the lounge, and kept them inside the conservatory, where I had deliberately left 1 small hole near the skirting, every so often, I would see an ant poke its head out of there, and have a wander around. That to me, meant, the problem was not solved, merely slowed down.Stage 2 = Find the entry point, given I had not seen any obvious routes into the house, and had placed ant powder outside the entire perimeter of the conservatory, without success, the only place they could realistically be coming from, would be under the patio door (again, this was not visible but seemed the only plausible route in).Out came the Dethlac, sprayed under the outside of the door, including the gaps around it, and the gap between the door opening/sliding part.The result, no more ants.I had been recommended Dethlac, by a family member. and noticed it was not readily available in the usual stores, and whilst I am not saying other products would not work, it would seem Dethlac is the best, certainly in my experience.I will probably re-spray the area every 2 months or so, over the summer, and that should hopefully keep the ants away.

Works well, have been using for years. Read the directions before use.

I have used this stuff before and it seemed to work. I say 'seemed' because one can never be sure whether or not the critters (ants in our case) went of their own accord. However, we had been ant free for two years when we had been pestered every summer for the previous 10 years when nothing seemed to work. I did note that my old canisters had an expiry date on them and the effect didn't seem to be as good when we were well past the expiry date (as we came into this new 2014 season). So, I have bought these new cans and my problem appears to be resolved again for the time being at least. I have seen no more of the ants for nearly a month. We were getting them from the skirting board in our pantry. I applied the spray around the places where they were coming through and they have disappeared. I have had better results when using Dethlac than when using another, different, popular spray. All I would say is 'follow the instructions on the can'. They are simple and easy to follow. If you are wondering how long it takes for the insecticide to stay 'fresh' then the expiry date on my two tins was August 2015. So order enough for the job in hand and order fresh next season if needs be.
