Police said jewellery was taken from two properties in Barrule Park during the day - taking the total to 32 homes in less than a fortnight.
Insp Derek Flint said 120 incident logs were completed on Tuesday compared to 37 for the same period last year.
Isle of Man residents have been warned by police not to attempt vigilante-style attacks on attempted burglars.
The warning follows what police labelled "wild speculation" on social media.
Insp Flint said "circulating untested information on Facebook puts others at risk and people must stop doing this".
He added: "A call to us with information is much more productive than the wild speculation that some individuals are resorting to on social media.
"Police are working flat out to catch those responsible but that, contrary to speculation, we haven't brought in any officers from the UK.
"This is being managed within our own resources."
Break-ins or attempted break-ins have been reported in Douglas, Onchan, Castletown, Port St Mary, Lonan and Ramsey.
Police are again asking for homeowners to remain vigilant.

The 32-year-old capped for both France and Martinique is a free agent after leaving Bordeaux last summer.
Saints boss Tommy Wright has also taken defenders Daniel Adejo and Plamen Krachunov on trial.
Wright said: "All three come with very good pedigrees and quality, but what we'll have to look at is fitness as well as ability."
Adejo joined Kalloni in 2014 from Reggina but left in January, the 26-year-old Nigerian having made 11 appearances for the Greek Superleague club this season.
Krachunov played eight times for Slavia Sofia this season in his homeland's top flight, the 27-year-old having joined from city rivals CSKA in the summer.
The central defender has played all his football in Bulgaria, his previous spells being with Maritsa Plovdiv and Lokomotiv Plovdiv.
Faubert, who began his career with Cannes, had spent three years back with Bordeaux in the French Ligue 1 before his release.
It was his second spell with Les Girondins, who he left to join West Ham in 2007.
During his five years with the English club, he had a short loan spell with Real Madrid before leaving to join Turkish outfit Elazigspor.
Faubert, born in Le Havre but of Martinican descent, made only one appearance for France, scoring on his debut in August 2006 against Bosnia and Herzegovina.
He used a legal loophole - the Martinican Football Association is not a member of world governing body Fifa - to make a second international debut.
Fuabert scored against Curacao and went on to score twice in his next two international games.

The private member's bill comes amid heated debate among government MPs about whether to change the law or put the matter to a plebiscite.
The government's official position is that marriage should only be between a man and a woman.
Prime Minister Tony Abbott has denied government MPs a free vote on any bill legalising same-sex marriage.
The bill allows couples, regardless of "sex, sexual orientation, gender identity or intersex status" to marry.
Australia's Marriage Act limits marriage to a union of a man and a woman.
The bill was introduced by government backbencher Warren Entsch, one of several government backbenchers who plan to defy Mr Abbott by crossing the floor of the parliament to vote in favour of marriage equality.
The ban on a free vote for government MPs means it is likely to fail.
Mr Abbott has said the matter should be "put to the people" in a non-binding plebiscite after the next general election, due in 2016.
Meanwhile, cross bench senators have backed an Australian Greens bill calling for a gay marriage plebiscite before the election.
In an impassioned speech, Mr Entsch spoke of how his bill, which has cross-party support, was designed to promote a more inclusive Australia.
"Being gay is not a lifestyle choice," the Queensland MP told the parliament.
"This bill does not create different classes of marriage," he said.
"A divided nation is what we will be if we continue to allow discrimination in relation to marriage on the basis of a person's sexuality."
An unprecedented spate of burglaries on the Isle of Man continued on Tuesday with the first break-ins in Ramsey.
